The question was whether the Fuji was worth it to achieve the OPs goal. I was sent this page by someone at Fotodiox trying to work out the equivalent focal length of a lens designed for a 6×7 camera on the GFX. Crop factor for Fujifilm X-T3 is 1.53 Save my name, email, and website in this browser for the next time I comment. Question… Fujifilm does make a 50mm f2 which looks almost identical (build wise) to the 35mm f2 but after you factor the crop in you get an equivalent focal length of 80mm which is too tight for an all-purpose and versatile lens, at least for me anyway. I.e. If we use the same density ore size of the pixels. So there is the same technology going into FF and MF sensors. It can be deceiving buying a crop sensor lens and thinking you will get the same amount of background blur as the full frame equivalent with the same f‑number. Since I am seeing a narrower FOV, I know that the crop factor must be greater than 1. When shooting handheld, a slow shutter can cause soft or blurry photos. Compared to what most would term full frame medium format, yes the GFX is a crop sensor. Fujifilm is considered by many to be the champion of the APS-C sensor space. Sorry, yes I totally misunderstood you there. This is a slightly complex topic and many long article have been written explaining it – but to keep it simple let me attempt a short explanation. Doesn’t make a lot of sense. DoF is a product of iris opening versus focal range in relation to the distance of a subject. Is this correct? Fujifilm X-Pro2 flagship X-mount camera is on its way and it will feature a bigger sensor with a 1.3x crop factor. Addressing the needs of multimedia image-makers, the black FUJIFILM X-T4 is a versatile mirrorless camera that blends advanced stills and video capabilities along with enhanced workflow and assistive functionality. c2 = a2 + b2 therefore c = √(a2 + b2) Full frame sensor dimensions: 36mm x 24mm therefore diagonal dimension is √(362 + 242) = 43.27mm amzn_assoc_search_bar = "false"; amzn_assoc_region = "US"; I am looking into moving to Medium format Fuji GFX. But 110/220 was good enough and survived, but it is only a common form of “medium format” and not the definitive size. So the rule of thumb for minimum handheld shutter speeds = 1/(focal length). There’s never been a more affordable way to get into digital medium format photography before, and whilst Pentax paved the way over recent years with the Pentax645Z, the new Fujifilm GFX system undercuts its price significantly, whilst also delivering a set of specifications that makes the Pentax camera look quite ancient. But how … Hi Williams. On APS-C you would use a 35mm F2 lens where you would use a 50mm F2 on FF. The 6×7 is just even larger! An 43 camera like the olympus with 16MP shall have 32MP on the area of APS-C and 64MP on a FF camera. Sharpness of the Fuji 35mm f2 If you want to know the equivalent aperture for Fujifilm X-T3, take the aperture of the lens you're using and multiply it with crop factor. Crop factor is the ratio of the diagonal dimension of two camera’s sensors. I’m not the one inventing this terminology, this stuff is used universally in the photography industry. The new mirrorless medium format Fujifilm GFX system has really shaken the camera industry lately, and judging by the initial responses from photographers I know, this is a format and camera system that’s going to be around for some time. If you know the width and height of a sensor, you can calculate the diagonal dimension using Pythagorean theory. The Best Black Friday & Cyber Monday Photography Deals In 2020, Crave PowerPack 2 – 50,000 mAh USB Battery Can Simultaneously Charge Your Camera, Laptop and More. Discussion in ' X-T Series: X-T1 T2 T3 T4 T10 T20 T30 T100 T200 ' started by Jeff Fa-Fa , Jan 7, 2019 . Ahhh! For more info check our privacy policy. Fujifilm X-Pro2 flagship X-mount camera is on its way and it will feature a bigger sensor with a 1.3x crop factor. Crop factor for Fujifilm GFX system = 43.27/54.78 = 0.79 GFX format sensor size: 43.8mm x 32.9mm therefore diagonal dimension is √(43.82 + 32.92) = 54.78mm You're asking for 6x4.5 this in reference to 35mm FF There are charts for 645/6x6 to 35mm out there. Since the GFX sensor is also much larger than full-frame. A 56mm ƒ/1.2 APS‑C (1.5x crop factor) lens is equivalent to an 84mm ƒ/1.8 full frame lens, not an 84mm ƒ/1.2 lens. | All content ©Shutter Muse - As an Amazon Associate this business earns from qualifying purchases. With a crop factor of about 7, it's the equivalent of a 28mm lens at f/13 on a 35mm-based sensor. Example 43 sensors used in the olympus and panasonic are 25% of the 24×36 (FF), APS-C is 50% of the area of FF and the 44×33 is 170% against FF. I have read the crop factor for Fuji cameras is 1.5, 1,53 and some says between 1.5-1.6. So if someone recommends a 200mm focal length, you can rightfully ask whether they mean full frame or crop sensor. Full-Frame or 35mm Diagonal / Crop Sensor Diagonal = Crop Factor So, if you have a camera with an APS-C-sized sensor (circa 15.6 x 23.5mm or 14.8 x 22.2 on Canon), plug in the numbers and you will get a crop factor of 1.5x (or 1.6x for Canon). This Fujifilm X-T4 is a pleasant change from other brands of cameras because it's much better made out of mostly all metal, and it has real, dedicated single-purpose individually marked dials for each of shutter speed, ISO, exposure compensation, advance mode, STILL/MOVIE mode, as well as a dedicated autofocus mode switch and two more general purpose control dials. Undoubtedly a 50 megapixel Canon will be absolutely fine for massive exhibition prints multiple feet across if used correctly. This is a good topic for another post at some point I’ll put it on my to-do list. A Detailed Review of the New Gura Gear Chobe 2.0 Camera Bag – Worth the Wait? We also both agree that the image quality from the Fuji would be better, but better dynamic range, for example, doesn’t translate into an ability to create larger prints. Fujifilm GFX Crop Factor and GF Lens 35mm Full Frame Equivalent Focal Lengths, Tamrac Anvil Super 25 Super Telephoto Backpack Review, Common Digital Sensor Sizes and Crop Factors, A Complete List of Fujifilm GF Lenses and Their Specifications, Review: ShutterCheck - How To Find a Canon Camera's Shutter Count, https://topazlabs.com/gigapixel-ai/ref/54, In-Depth Review of the MindShift Rotation 34L Camera Bag. Or am I doing this all wrong? Dan is also the President of the First Light Image Festival. I see. 6 x 9 Crop Factor = 0.43. Many people are familiar with the two common APS-C crop factors: 1.6x for Canon, and 1.5x for Nikon, Sony and everyone else. This factor determines the equivalent field of view of a lens when used on a camera with a sensor that is either smaller or larger than our reference full frame sensor. Manufacturers often provide the horizontal and vertical dimensions of a sensor, so we can use Pythagorean theory to calculate the diagonal dimension. The Fuji cameras have a sensor that produces a 1,5 crop factor - so a 35 mm lens on a Fuji camera produces 52.5 mm view compared the a Full Frame camera without a crop factor… If you want to calculate relative crop factors, you simply look up sensor sizes and divide the sensor dimensions of … “Medium Format” is anything larger than 35mm but smaller than 4×5. In digital photography, the crop factor, format factor, or focal length multiplier of an image sensor format is the ratio of the dimensions of a camera's imaging area compared to a reference format; most often, this term is applied to digital cameras, relative to 35 mm film format as a reference. I must not have been very clear, or I am misunderstanding you. However, the focal … The sharpness of the images, assuming you are using top end glass on both, would be relatively similar and probably not contribute much to the decision of how large you would print…, So yes, the GFX will give you a better image in terms of dynamic range and tonality, but it doesn’t necessarily mean you could print it much larger as they would be similarly sharp. And a 23mm lens would be the equivalent focal length of 34.5mm on a … You might want to look at this incredible software: https://topazlabs.com/gigapixel-ai/ref/54. Full-Frame or 35mm Diagonal / Crop Sensor Diagonal = Crop Factor So, if you have a camera with an APS-C-sized sensor (circa 15.6 x 23.5mm or 14.8 x 22.2 on Canon), plug in the numbers and you will get a crop factor of 1.5x (or 1.6x for Canon). A 50MP medium format sensor will ALWAYS out perform a FF 50MP sensor/frame. One model was supposed to feature a 24-megapixel APS-C sensor, while the other one was said to come with an APS-X-sized (bigger than APS-C) image sensor with a megapixel count situated between 25 and 27. What printer will be used? Same reason why aps-c digital cameras came to market first before full frame 35mm. If full frame MF becomes financially viable, people will have to buy all new lenses. Everbody can consider what important is for them self. Fuji, Canon and Nikon work exactly the same and had you bought the Fuji 18-55 zoom, it would have given you exactly the same range as the Canon EF-S18-55. This software can definitely enable you to make some larger prints and it might be worth trying that first with your 5Ds before investing in an entire new system. Canon crop sensor cameras have a 1.6x crop factor. indeed medium format is everything larger then 24×36 and smaller then 4×5 inch, the cropfactor range is referenced to the diagonal of 24×36. The 6 x 9 format has the same aspect ratio of 2:3 found in 35mm film and full frame image sensors. In the title of the post, it says “35mm full frame equivalent” so it’s implied that this is our baseline. The Fuji X100V is a handsome all-metal camera with real knobs and dials which makes it very easy to set and control from shot to shot. Your email address will not be published or shared. 110/220 is really a format produced for the Brownie No.2, which was an amateur camera. All current Fujinon lenses will be compatible with the Fujifilm X-Pro2. The crop factor of Fuji cameras with APS-C sensors is 1.5×. Even so important is de square usable size of a sensor in relation to the number of pixels. No, of course not, because the vast majority of people aren’t familiar with the field of view from such a camera so it would create unnecessarily awkward numbers for people to constantly deal with. amzn_assoc_placement = "adunit0"; Built with Divi. Full frame sensor dimensions: 36mm x 24mm therefore diagonal dimension is  √(362 + 242) = 43.27mm, GFX format sensor size: 43.8mm x 32.9mm therefore diagonal dimension is  √(43.82 + 32.92) = 54.78mm, Crop factor for Fujifilm GFX system = 43.27/54.78 = 0.79. With the Fuji, your main advantage is probably going to be the better dynamic range since the pixel count is the same. Math is not my strong suit, so I’m not sure if I’m doing this right, but it seems to me based on the math above the calculation would look something like this: 6×7 size: 56mm x 67mm therefore diagonal dimension is √(56^2 + 67^2) = 87.32mm. The FUJIFILM X-T3 is the world’s first*5 mirrorless digital camera capable of internal SD card recording 4K/60P 4:2:0 10bit. amzn_assoc_tracking_id = "shuttermuse-20"; Same thing. If I multiply the 43mm focal length by .4955 that would imply I should see a wider FOV on the GFX, rather than a narrower one. I’ve seen this before when examining their tech specs, so I think this is a general observation about the X system’s crop factor. The term crop factor refers to the ratio of a specific sensor to a 35mm full frame sensor. I think this was in reply to serge barbeau. There has to be some reference point, and in the photo industry we use the 35mm simply because it is these focal lengths that everyone is most familiar with. The part you got wrong was “I assume then since we’re going the opposite direction, from a larger sensor down to a smaller”. Smaller cuts tend to give higher yields. So your Fuji XF 18mm f/2 lens – and what a beauty it is – would be the equivalent of 27mm. Tri-X pushed in 135 was pretty painful, but OK for half tone pictures. Do you need to crop? Pixel to pixel, dynamic range, color, depth, DOF, shadows and highlights, enlargements, etc. Since the GFX system has a sensor that is larger than full frame, we can expect our crop factor to be less than 1. Please note that if you include a link in your comment, it will have to be moderated first before it appears on the site. By submitting a comment this form also collects your name, email and IP address so that we can prevent spam. In the case of digital cameras, the imaging device would be a digital sensor. It varies by manufacturer (Canon is 1.6x and Nikon is 1.5x), but we’ll use 1.5 as an example here. Before digital, 35mm film was a reference format due to its mass adoption and popularity. Just like crop factor for cameras, a Nikon DX has a crop factor of 1.5 because the ratio of the sensor widths are 1.5, not the areas. amzn_assoc_title = "Related Products"; Fro instance the crop factors are - CSC = 1.5 FF = 1 mu4/3 = 2 it all depends on the size of the sensor! Fro instance the crop factors are - CSC = 1.5 FF = 1 … The fact that you are asking the question suggests your knowledge/skill doesn’t match your gear. Actually we’re going the same way as the GFX calculation. ….wow , anyway thanks for the chart, very usefull. I believe Fujifilm has a real winner on their hands here, so I’ve decided to add some content and resources to the site relating to this interesting system. How far away will they be viewed from? This option delivers two benefits: faster burst shooting rates, and a higher 1.25x crop factor that makes framing distant subjects easier. It measures 101mm diagonally. Has to do with silicon manufacturing yields. OFF: The 1.25× crop is disabled. This would mean a 50mm lens requires a minimum shutter speed of at least 1/50 for a sharper image. It is about as wide as you see before moving into panoramic cameras, which I’m not covering for the purposes of crop factor comparisons. I assume then since we’re going the opposite direction, from a larger sensor down to a smaller, we’d divide 87.32 by 54.78, giving a crop factor of 1.59. All current Fujinon lenses will be compatible with the Fujifilm X-Pro2. Crop factor for Fuji & Sony. Pictures are taken using a 1.25× crop, reducing the picture angle by an amount equivalent to increasing lens focal length by 1.25×; the crop is shown by a frame in the display. Without these pieces of information it is an impossible question. As Rob pointed out below, large format predates medium format, and if you want to really split hairs, should be be basing our factors on the size of daguerrotype film? https://www.dpreview.com/forums/thread/4305965#forum-post-61459143. For practical considerations, it is relevant. We both seem to agree that the Canon is more than enough. It is smaller than true medium format and therefore that crop creates a magnification factor. If you wanted to produce square or 4×5 images it might be different. Hi, thanks for all the GOOD info. Micro Four Thirds cameras have a focal length magnification factor of 2x. It can be deceiving buying a crop sensor lens and thinking you will get the same amount of background blur as the full frame equivalent with the same f‑number. Is it worth it to achieve my goal..? It would make sense, considering “full frame” small format digital takes its size from the frame size of 35mm film. However, the focal … Sensor size is irrelevant to DoF. Wait. Great for portraits though. What you are calling crop factor is really a MAGNIFICATION FACTOR. Current Q-series cameras have a crop factor of 4.55. Since Fuji cameras have the "correct" size of APS-C sensor, the crop factor is 1.5x. Higher ISOs and stopping down just to get a decent depth of focus. Whether you’re using a Canon APS-C camera (crop factor 1.6) a Nikon APS-C camera (crop factor 1.5), an old Nikon 1 with a 1-inch sensor (2.7x crop factor), or … You can find information on the sensor size in your camera in the manual, product information of the manufacturer of on DPReview.com. I wonder in time if Fujifilm will regret designing lenses for the cropped MF format, though? I have a Canon 5d/s , 50 Million pixel sensor. As for calling it crop vs. calling it magnification factor, they are exactly the same thing. Bertrand Yes is Very relevant, try shooting with a GFX kit the shallowness of your DOF is one of the first things you have to adjust to. Aperture is a lens characteristic, so it's calculated only for fixed lens cameras. The crop body I used here was the Fuji X-T2 which has 24MP, and the full frame body was the Sony A7R II with 42MP. No Fujinon FX lenses are for use on X mount cameras only! So if someone recommends a 200mm focal length, you can rightfully ask whether they mean full frame or crop sensor. Yes, but try thinking about it this way: Roughly half of the width of the sensor is used on the 75mm crop, which means also half of the height, which translates to using around a quarter of the resolution. The Fuji X-mount cameras have a crop factor of 1.5x, though this is not an entirely accurate figure, as Fuji actually cites the full frame equivalency of the XF90 as 137mm rather than 135mm (more like 1.52x). Since most people are used to seeing focal lengths in 35mm terms, it’s a bit confusing for many of us to see the focal lengths of the new Fuji GF lenses, and immediately comprehend how wide, or telephoto the lenses are. His editorial work has been featured in publications all over the world, and his commercial clients include brands such as Nike, Apple, Adobe and Red Bull. To state it more succinctly: Small format digital is based around 35mm film as a sizing standard, but medium format is not based around medium format film. Crop factor is the ratio of the diagonal dimension of two camera’s sensors. used to capture the same image for a given lens. Canon crop sensor cameras have a 1.6x crop factor. Sets on top dial: lift shutter speed dial collar and turn — or set the "C" position on the dial to set it in a menu. Comparing the FOV in the GFX viewfinder vs. the viewfinder on the 6×7 camera it is clear that the focal length is effectively longer on the GFX than it is on the 6×7. If you know the width and height of a sensor, you can calculate the diagonal dimension using Pythagorean theory. One model was supposed to feature a 24-megapixel APS-C sensor, while the other one was said to come with an APS-X-sized (bigger than APS-C) image sensor with a megapixel count situated between 25 and 27. I’m glad you got it figured out. In other words, 35mm full frame equivalent fields of view will be larger than the quoted focal length for any given GF lens. One term that you’re certain to come across when researching your next DSLR purchase is ‘Crop Factor’. Example: With a Fuji 23mm lens, minimum shutter speed will be 1/(23×1.5) = 1/34.5. Thanks for joining the conversation, Ricardo! The term “crop” is universally accepted in the industry. Hopefully this makes my question clearer. My goal is to make large prints in 35mm print format and slightly thinner and longer prints. And a 23mm lens would be the equivalent focal length of 34.5mm on a full frame camera. So … the 35mm sensor has a crop factor of 54.78/43.27 ~= 1.27 and an APS-C sensor would have a crop factor of approximately 1.9. The important thing to know is that the crop factor is the ratio of the diagonal dimension of the sensor. So the 43mm Mamiya 7 lens on the GFX gives a FOV that would equal an approx. Wait. Nearly right. There is 2.25 times more space on the full frame sensor, meaning, if it were packed as tightly as the crop, there would be 24MPx2.25 (1.5x1.5 crop factor) = 54MP pixels. Do we know what exact (accurate) crop factor for Fuji? A techical fact in every sense but practically speaking in the context of laymen, it does not tell the whole story. 50mp from the canon is more than enough. So if you're every wondering why the cameras in iPhones and other smartphones have so much depth of field, it's simple -- the sensors are so tiny that when applying the crop factor, you have a … . Crop meant to reduce the size and Blow up meant to increase. Their sensor size equals a 1.6x crop factor, whereas all other APS-C systems have a 1.5x crop factor. So if you're every wondering why the cameras in iPhones and other smartphones have so much depth of field, it's simple -- the sensors are so tiny that when applying the crop factor, you have a … amzn_assoc_asins = "B01MZARM64,B01MR6Z8Z2,B01MS8EWXM,B01MZARLEQ"; Professional photographer based in the Yukon, Canada, and founder of Shutter Muse. Full sized medium format is not yet cost effective in this age but crop medium format already is. But with a Fuji APS-C sensor, you need to factor in (no pun intended) the 1.5× crop factor. You can only compare DoF by looking at aperture if you maintain the same sensor size. The GFX is NOT A crop sensor camera. A crop factor of 1.5 is applied to the engraved focal length to give the equivalent focal length if used with a full frame camera, which they can't! As emulsions improved in the 40’s, 50’s and 60’s 135 and 110/220 overtook the large format press cameras. That means that sensors that are smaller than a full-frame (35mm) sensor will crop out a part of the image that's received by the lens, effectively cropping the image. Like Like Crop factor for Micro Four Thirds. ... 1.52× crop factor. Erm no Crop comes from old school dark room practices. Home » Tutorials » Fujifilm GFX Crop Factor and GF Lens 35mm Full Frame Equivalent Focal Lengths, Posted by Dan Carr | Jan 22, 2017 | Tutorials. | Hosted by Kinsta. Thanks for joining the conversation Roger. While normal film cameras take 35mm film (it … It is also the world’s first*5 mirrorless digital camera with APS-C or larger sensor capable of 4K/60P 4:2:2 10bit HDMI output. Like Nikon, Fuji and Sony APS-C format cameras will produce around a 1.5x crop factor. This Fujifilm X-T4 is a pleasant change from other brands of cameras because it's much better made out of mostly all metal, and it has real, dedicated single-purpose individually marked dials for each of shutter speed, ISO, exposure compensation, advance mode, STILL/MOVIE mode, as well as a dedicated autofocus mode switch and two more general purpose control dials. This should not present a problem, although Canon lenses for APS-C are actually made for 1.6x crop How large is large? You make some good points RE aspect ratio and cropping. Since medium format predates 35mm film, the 35mm is the CROP SENSOR. The crop factor of Fuji cameras with APS-C sensors is 1.5×. When full-frame sensors were first introduced, production costs could exceed twenty times the cost of an APS-C sensor. Nikon, Fuji, and Sony crop sensor cameras have a 1.5x crop factor. HOWEVER you have given bad advice here IMHO. What is the right way to calculate the focal length change moving from a 6×7 lens to the GFX? A crop factor of 1.5 is applied to the engraved focal length to give the equivalent focal length if used with a full frame camera, which they can't! What this means is that a 35mm lens on a Fuji X-T3 is the equivalent focal length of 52.5mm on a full frame camera. I never imagined a Company which has only APS-C sensor would sell lenses with Crop factor. 70mm Mamiya 7 lens. so actually we get more shallow dof from full frame camera with those very large f stop lens. What this means is that a 35mm lens on a Fuji X-T3 is the equivalent focal length of 52.5mm on a full frame camera. The aperture is just a measure of the amount of light that can come in through the lens. Jeff Fa-Fa Premium Member The crop factor of Fuji cameras with APS-C sensors is 1.5×. The calculation above, in your original post, is for determining the effective focal length of a lens intended for a 35mm sensor on the larger GFX sensor. The 35mm lens has more depth of field than the 50mm.QED. amzn_assoc_linkid = "3be6f6084aa5187ba3c6f9775c35902e"; So really its a Blow Camera, which to be honest if you can afford Medium format you can probably afford Blow too . What lenses? And “large format” predates medium format, so I guess we’re all full of crops…. But what I’m after is the calculation for the effective focal length of a lens intended for a larger sensor, the 6×7, on the smaller GFX sensor. Most of us are used to seeing crop factor as a number greater than 1, for example APS-C is typically has a crop factor of 1.5x or 1.6x. Sportfinder mode and crop factor? What does it mean: Bigger pixels means more catching light, higher contrast and more color information and less need to ultra high resolution lenses. Excellent points! You are splitting hairs here for the sake of argument. Wait. amzn_assoc_marketplace = "amazon"; With a crop factor of about 7, it's the equivalent of a 28mm lens at f/13 on a 35mm-based sensor. Why you still shouldn’t bother with 4K in 2020, 5 things you must know before buying a new TV in 2020, Fuji 18-55 vs 16-80 zoom range comparison. If one used a 50mm lens on an SLR film camera, everyone knew exactly what it looked like in terms of field of view and the resulting image, so understanding and discussing different lenses and focal lengths was easy. No Fujinon FX lenses are for use on X mount cameras only! Crop factor for Fujifilm GFX system = 43.27/54.78 = 0.79 GFX format sensor size: 43.8mm x 32.9mm therefore diagonal dimension is √(43.82 + 32.92) = 54.78mm You're asking for 6x4.5 this in reference to 35mm FF There are charts for 645/6x6 to 35mm out there. With this in mind, the rule of thumb for Fuji APS-C cameras becomes shutter speed = 1/(focal length × 1.5). Required fields are marked*. So basically it’s close enough to 0.5 that you could round up and use that. Serge. In digital photography, the crop factor, format factor, or focal length multiplier of an image sensor format is the ratio of the dimensions of a camera's imaging area compared to a reference format; most often, this term is applied to digital cameras, relative to 35 mm film format as a reference. Then you simply divide the diagonal dimension of a full frame sensor, by the diagonal dimension of the sensor for which you want to find the crop factor, GFX system in our case. If you’re just looking at the apertures, you can’t really tell. What’s also interesting to consider, is that Sony is making all these MF sensors anyway. This is a brief video tutorial on sensor formats, explaining sensor size and area, crop factor, focal length and f-stop in both worlds. Silicon manufacture is not a perfect process. Due to technological challenges and high manufacturing costs, making digital camera sensor sizes that matched the size of 35m… Personally, I don’t like shooting under 1/60 on any lens if I don’t have to, but that’s just me. Crop sensor cameras or APS-C cameras have smaller sensors, and the resulting image magnification is called the crop factor – as you can see in action in the images above. It would be 43.27mm/87.32mm = 0.4955. Is the 5D/S not producing prints of high enough quality or have you not even tried yet? More information on the how an why of the Lens Multiplication Factor (also referred to as 'Crop Factor') can be found on WikipediaWikipedia Thanks. A crop factor is the multiplier that needs to be used to compare the full-frame equivalent focal length and maximum aperture of a lens when used on a different-sized sensor. Nikon, Fuji, and Sony crop sensor cameras have a 1.5x crop factor. To be able to compare the field of views from full frame and GF lenses, we need to know what the crop factor is for the GFX system. Using the calculated crop factor of 0.79, we can now see the 35mm equivalent field of views for all the Fuji GF lenses.
