how to calculate that? Notice I haven't said anything about depth of field. The history behind crop factor is long, but what you need to know is that focal length is described using 35mm film as the reference point. Popular 6 x 8 medium format cameras are pretty much limited to the Fujifilm GX-680, GW680 and GSW680. Nikon and Sony APS-C cameras yield a 1.5x crop factor, while Canon APS-C cameras have a 1.6x crop factor. It is hard to explain why. Popular 645 format lenses and their 35mm equivalents. With the release of the Fujifilm GFX 50R, the Hasselblad X1D II 50C, as well as a burgeoning used market, digital medium format has become more attainable than ever by professional photographers wanting to step up to the next level in image quality. However, "Full Frame Plus" just doesn't have that same ring to it, does it? More importantly, smooth gradation is not only the easiest thing to interpolate digitally, but also cannot really be displayed on our 8-10 bit screens, much less in print. It will be the same as if you put a 75mm Pentax K mount lens on your camera, but you’ll be using only a portion of the image circle. Nowadays, the term applies to film and digital cameras that record images on media larger than 24mm × 36mm, but smaller than 100mm × 130mm, which is considered to be large format photography. The issue of crop factor becomes even more convoluted when taking in to account the smaller formats such as micro four-thirds, one inch and the point-and-shoot formats. Good point. This answer does not make sense. MF – Medium Format Wait. Of course, the author has gone to great lengths to explain that while 35mm film cameras and DSLR’s produce a 6×9 image that is not the case in the medium format world where formats vary, such as cameras that take square pictures (i.e. What do you think? To clear up confusion my opinion manufacturers should use the following definitions: T- Stop – To describe the effective light gathering capacity of a lens regarding to a certain sized sensor (film format)(not just for video). "Tonality" usually refers to a combination of this and resolution, except that nobody knows what it refers to exactly. Why don’t we just express it as an angle of view, calculated for the format and the particular focal length lens in use? You managed to write an entire article about a meaningless buzzword. Simply input your focal length, sensor size, and max aperture and we'll give you what the 35mm equivalent is of that configuration. This was important in the early days of digital photography, when photographers switching from film needed a quick way to know what to expect when using their lenses on digital cameras. You said above that a 50mm full frame lens on a APS-C camera is like an 80mm field of view due to the 1.6 crop factor. Don’t even get me started on their color requirements! Fuji GFX 100 Review After Using It Professionally for Three Months, Part One: Value, Image Quality, Handling, and Comparison to X-T3. Since the focal length has changed, then too has the f-number. In case you don’t know what a medium format camera is, we’ll explain it briefly. Remember, focal length is the distance from the optical center of the lens focused at infinity to the camera sensor / film, measured in millimeters. Of course, most of us understand that this is a misnomer and that the 50mm lens does not change at all to become an 80mm lens when used on a different camera. It has nothing to do with physical distance, as we aren't exactly getting close to the planck length here. This article explains what I think about when I think about focal length. Yes, I was assuming that the light intensity per unit area incident on the sensors was the same. Kudos to your wikiresearch, but you’re not helping anyone. The 200mm focal length of the 645 lens is effectively the same as a 125mm lens on a 35mm camera, and when we crop the image by using the 200mm 645 lens on a 35mm camera, it effectively becomes exa… Anyone that’s shot a DSLR in a remotely serious manner is aware of the crop factor for APS-C format cameras when compared to their full frame cousins. To obtain a sensor that is close to true medium format size, you can expect to pay north of $50,000! In order to have a shot in bringing this new product to market, the cost could not be astronomical. It would be instantly meaningful when considering the scene to be photographed. In order to confirm this, first of all, it is necessary to know in advance the focal length of a lens of medium format digital camera as to which focal length lens is the same as the focal length lens of 35 mm full … So, what is medium format? I feel that large sensors have better tones. It's that simple. F-stop – To describe the DOF a lens is able to produce. That's science. The human eye is only so perceptive, and trying to discern smoother tonal changes on Instagram just ain't gonna happen. Thanks for the laugh dudes . Yes, it is. This is definitely not the best camera for amateur photographer. I can't say I blame you! Wait. The advantages of medium format are greater resolution potential and better, smoother tonality. If you divide 36mm by 25.1mm (36/25.1), you get 1.43. If you mount a 400mm lens on a full frame camera, it gives you shots taken at 400mm. @Brent Daniel Actually that's not necessarily true, let's say the smaller sensor is 1/2 the bigger one, the amount of light reaching each of those 1000 pixels depends uniquely on the lens you are using, if you are using a lens that gives you the same FoV but is 1 stop faster on the smaller sensor you will end up with the same amount of light on each pixel = same shot noise. My apologies for the long explanation but many people seem to be touting misnomers on effective light gathering capacities (referring it to F stop), effective focal lengths (FOV not magnification/crop factor), DOF etc. But did you know that a smaller sensor essentially magnifies focal length? APS-C, or cropped sensors, were born as a compromise between economy and quality. Here, full-frame DSLRs very much have an advantage over relatively new medium-format systems. You're right about the bit depth it does make a difference. film/sensor area) as any other 75mm lens. The 6 x 9 format has the same aspect ratio of 2:3 found in 35mm film and full frame image sensors. The crop factor is also used on the aperture to give us the maximum effective aperture equivalent on a full-frame camera. GFX 50S lens focal length and 35mm full-frame equivalent focal length. I hang my prints, I sell those and no one ever goes to pixel peep anything, even if they would, they wouldn't see the difference between GH4 and A7r III. The videos […] That's why you can easily see the difference in tonality on film. On Food shots I get ADs that insist they live view and approve before we take final shot. The comparison would need to be made between sensors of relatively the same res. That simply isn't true. The advantage of medium format however is the fact that if the surface is bigger first you get more dynamic range, and second the lens you need to use to capture a certain amount of detail works at lower MTF compared to the one you would need for that same detail on a smaller sensor. Which Camera Manufacturer Has the Best Logo? The new GFX and Hasselblad cameras, although amazing, do not have true medium format size sensors. Now, bokeh mania has taken over and medium format has been equated to that shallow look. That’s the crop factor. Thank goodness for the wireless revolution, else Hans might have to learn to photograph in a full body cast. From then on, digital sensor size fever has run rampant. So, a 17mm lens used on such a camera will provide an effective focal length similar to a 34mm lens on a full-frame body. I was looking at some comparisons between 14 and 16 bit both with the GFX-100 and there didn't seem to be much difference. If somebody wants to test this, please take m43-camera with a 25 mm lens and use, lets say, f/2.8. Here that, Hans Rosemond! If you keep the shutter speed same, you will get exactly the same result. The smallest true medium format size, 6x4.5, is a full 2.7x larger than full-frame, while 6x7 has an astounding 4.76x more area! This one is extremely important to understand. I made so, don't care the pixel peeping when I know a 1x1 cm area in a 30x20" print where to look at the difference that would reveal it by comparing two prints side by side multiple times. The 645 format frame is 56mm x 41.5mm. But, as with those crop sensor “equivalencies”, you’ll run into the same re-thinking of focal lengths in reference to film size. That means that a given lens gives you more detail the bigger the sensor is (as long as it can cover it of course), and that's why FF lenses perform better on FF than on APS-C bodies. But you get the idea. In photography, medium format simply refers to a camera that has a larger sensor than a 35mm (24x36mm), or full frame DSLR camera. In the grand scheme, this whole shallow depth thing is a fad. The choice of lens/aperture certainly impacts that. Bigger wells means lower noise means an ability to resolve smaller tonal increments. Everyone:... One question, if I put a 6×7 75mm lens on a 35mm “full frame” dslr (like on a Pentax K-1), what would the accurate field of view be? 52.5mm* equivalent, sorry. Take a shot and compare that to a "full frame" camera with 50 mm lens and f/5.6 and two stops higher ISO. Medium is an open platform where 170 million readers come to find insightful and dynamic thinking. 80-90% shouldn't see any difference, and rest who does, shouldn't care the difference. A lens with a focal length of 50mm mounted on an APS-C camera, for example, has a similar field of view to a 75mm lens on a full frame camera (50 x 1.5 = 75). Damn, I wish you people learn to understand the context before saying completely irrelevant and inaccurate things. Not really. Perhaps the best place to start with this topic is to look back at an earlier technological marvel: APS-C. Why? Nikon was eager to sell bodies, and marketing the new cameras as cropped sensors wouldn't have helped their cause. This is only a problem when there is a common mount shared between cameras with different aperture plates, like Nikon’s F mount, for example when using Nikon DX lenses on Nikon FX/35mm cameras.
