The crop factor for that sensor is 1.5x. Thank you for the great insight. (Naturally, assume the same lens, sensor megapixels, pixel-level performance, aspect ratio, people jumping in front of the camera, and the camera’s mood that day. Sure, a thousand little differences mean that your photos will never look identical even after you get the math right. (note reducing the sensor size makes it a darker lens, not a brighter one, sorry) As sensor size decreases, depth of field will increase for a … Unfortunately, we can’t side-step the science here. And this only applies when your fields of view are matched already – after you’ve zoomed in with the larger sensor. If you’re at ISO 100 on the APS-C camera, you would need ISO 100 * (1.6^2), i.e. mount could be made for it,  a 50mm lens The 645 Format – The Best Entry Level for the Medium Format Camera. But since you’re at base ISO on both cameras, the large sensor is likely going to win in terms of things like dynamic range and color depth. As you can see, you need to square your crop factor first. You can debate all day about sensor efficiencies, lens T-stops, X-Trans vs Bayer, CCD vs CMOS, and a million other things. ... frame equivalent of f/1.2-1.4 maximum aperture. mathematically-inclined people have designed complex As I said a moment ago, the exact fix is (f-number) x (crop factor). Further, if you crop the MF image to a For example, say that you’re trying to calculate equivalence between an APS-C and medium format camera. obviously a much larger amount of the scene will be Nasim’s famous quote, “Everyone is right, everyone is wrong,” has been etched both into the peace treaty and into the hearts of millions. focal length of lenses). This allows for better tonality (smoother gradations), finer detail, and less apparent grain. Is medium format popularity on the rise? For example, a 100mm lens on a 1.5x camera is like a 150mm lens on full-frame camera, at least for field of view. 2� square format focal lengths. Or, if you’re deciding between two camera systems, it helps to know exactly what you’re giving up with one versus the other. The 645 format relatively seems to be something seen as a small format, but it is usually 60×45 mm on 120 medium-format … My understand is as follows which is slightly different , I am wrong? Also by magic. Hi Heikki, in your example, the ISO values will not be the same, assuming your goal is to get the same image brightness. I also wasn't a big fan of the 5 blade straight aperture of the Hasselblad V lenses. Medium format mirrorless systems are a great way to get into photography with a sensor that’s larger than a full frame 35mm sensor, so long as you can afford the higher price point. angles of view. That’s two stops of difference. So, if your large sensor is at base ISO, you probably can’t do the ISO part of equivalence; the small sensor simply can’t go low enough to compensate. Am I missing something obvious? This gives the X1D a versatile multi-purpose optic, and effectively an everyday lens if you'd like to use your Hasselblad as as a walkabout camera. formulae to �convert� 35mm format focal lengths to Note: For a quick understanding of numbers like 1/2.3, skip to table of sensor formats and sizes. What were you thinking? One chooses a camera and a lens. results of these calculations may be misleading, as To get a good approximation of the 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 … offer a lens with a focal length of 135mm. approach. By checking this box I consent to the use of my information, as detailed in the Privacy Policy. For a simplified discussion of image sensors see image sensor.. In digital photography, the image sensor format is the shape and size of the image sensor.. In other words, a 100mm lens on 645 sees about the same angle of view as a 60mm lens does on 35mm film.. A 50mm Normal Lens on Every Format Since 50mm is the most common focal length (at least on prime lenses), let's find the equivalent of a 50mm lens on every format. a 50mm 6�6 lens is roughly equivalent to relationship between 6�6 and 35mm, take the 6�6 ), though some I am confused about one thing…and this may be a bit unorthodox. Medium Format ; Hasselblad XCD 21mm f/4 Lens Rp 56.150.000 Warranty: Garansi Resmi 1 Tahun . The Fujinon GF 32-64mm f/4 R LM WR is the only zoom lens so far for Fujifilm’s medium format G Mount and cameras with the 43.8 x 32.9 mm sensor with which it covers a focal length range equivalent to 25-51mm. When they come to Medium It’s the only way to match the fields of view between the images. Quite simply, now that we’ve entered a bit of a cool-down period on the equivalence debate, it’s become a good time to turn back and examine it with rational heads. A number of years ago I ... as small as vintage medium format goes). Who would have guessed? Various mathematically-inclined people have designed complex formulae to “convert” 35mm format focal lengths to 2¼ square format focal lengths. Medium format brings with it bulkier and heavier lenses mated to large cameras, but what of medium format with a top-performing lens of the same weight as even diminutive Leica M rangefinder lenses? Divide by 2 = 25mm. I want to understand this so please reply. Are Canon and Nikon the only reputable makers? The XCD 30mm F3.5 is a wide-angle prime lens for the Hasselblad X1D and 907X 50C medium-format camera systems. Hopefully, a math-based understanding of equivalence, especially the main takeaways, will help you avoid that fate – or, if it’s doomed to happen either way, at least dominate the discussion boards and prove to everyone that you’re the Best Photographer™. Carl Zeiss Jena and Arsenal are also slightly exposure), a certain amount of the scene will be 77mm Filter Size f/2 Aperture N/A Stabilized G Mount Mid-telephoto lens for portraits High Image quality This medium telephoto lens with a focal length equivalent to 87mm in the 35mm format offers fantastic bokeh thanks to its large F2 aperture, making it the perfect portrait lens. square. Thanks for helping me help you! While I’m at it, I’ll mention another thing: this is only talking about depth of field. Was looking for some good data about ISO equivalence, and finally found it. = 22mm, Back to beginning of the On 1.5x APS-C sensors, that’s f/4 and f/6, roughly 1.3 stops of difference. rectangle, you will of course be reducing the angle So, the entire discussion below assumes that you’re standing still, because otherwise you might as well be reading a completely different article (like Elizabeth’s on lens compression). recorded. than 120mm � I do not have the technical equipment Characterized by its especially slim design, the GF 50mm f/3.5 R LM WR Lens from FUJIFILM is a compact 40mm-equivalent prime designed for the medium format G-mount GFX camera system. However, standard smartphones have tiny sensors with a 7x crop factor versus full-frame. When you do set ISO 100 and f/1.0 on the aps-c camera, and ISO 250 and f/1.6 on the FF camera (assuming you use equivalent focal lengths on both cameras; i.e., 100mm on aps-c and 160mm on FF), your photos will be fully equivalent. The image sensor format of a digital camera determines the angle of view of a particular lens when used with a particular sensor. But if you don’t at least take into account focal length, aperture, and ISO, you’ll never get equivalent photos across different camera systems. Lens Data section, To go back to the beginning of the Accessories directly on a medium format camera, for two reasons: Various To take equivalent photos, you’ll be at f/4 on a 1.5x sensor alongside f/6 on a full-frame sensor. (They aren’t hard, and I’ll cover them below.) Compared to 35mm, medium format uses 3~4 times as much film surface. Condition is "Used", … Before we start, what is equivalence? The formula for equivalent focal length is easy: (focal length) x (crop factor). Note: On Photography Life, we already have a very detailed article on equivalence here. Lens Data section, click below and then choose the a 28mm lens on a 35mm SLR, Another example:  40mm The lens is designed for Hasselblad's digital 'medium-format' which features a 44x33mm camera sensor size and a 0.79x magnification. Why Focal Length Is Clearly Part of Equivalence, Sometimes, Equivalence Isn’t Possible with Your Gear, Print Size, Total Light, Airy Disks, Circles of Confusion, and Eigenvalues, A System to Pick the Right Shutter Speed, Aperture, and ISO, Understanding ISO, Shutter Speed and Aperture - A Beginner's Guide, Nikon D300 vs D90 High ISO Noise Comparison, Z6 II vs. Z7 II – advice on which one better for enthusiast level, To watermark or not to watermark on prints, Equivalent Focal Length = (Focal Length) x (Crop Factor), Equivalent Aperture = (F-Number) x (Crop Factor). On top of that, I believe that learning the advanced technical side of photography makes it easier to internalize the basics, something that directly impacts the quality of your photos.
