This is The Digital Story Podcast 1,045, March 31, 2026. Today's theme is, "Why I Revisited Crop Sensor Mode on a Full Frame Camera." I'm Derrick Story. An APS-C sensor isn't exactly chopped liver, right? And it becomes even more alluring when it's extending the reach of your telephoto by 1.5X, and with no light loss! But you do lose a bit of resolution, and that was a speed bump for me. But I'm over it! And I'll explain why, plus industry news, in today's TDS Photography Podcast. I hope you enjoy the show.

Apple Podcasts -- Spotify Podcasts -- Stitcher Podbean Podcasts -- Podbay FM -- Tune In Why I Revisited Crop Sensor Mode on a Full Frame Camera Captured in crop-sensor mode with a Nikon Zf and 28-400mm Z zoom. What is crop sensor mode? Many full frame cameras have a crop sensor setting that provides 1.5X or 1.6X magnification. Essentially, this mode uses the center area of the chip and not the full 35x24mm surface. This allows photographers to use compatible crop-sensor lenses, call DX in Nikon terms, on a full-frame body. But it's also a way to extend the reach of a full frame optic without having to add a physical teleconverter. The catch is, since you're only using part of the sensor, the resolution decreases. In the case of my 24.4 MP Nikon Zf, I co from 6048x4032 pixels in FX mode, to 3984x2656 in DX mode, which is 10.6 MP. Unlike digital magnification that interpolates pixels, these are real pixels right off the sensor. DX mode renders both the JPEGs and the RAWs the same resolution. There is savings in file size too. A DX RAW from my Zf is around 14.6 MBs compared to FX at 30.9 MBs. Why did I revisit DX mode? As I mentioned earlier, dropping down to 10.6 MP was a speed bump for me. Sure, for publishing online, 3984 pixels on the longest side was more than enough. But beyond that, let's say for printing, it's a bit short. Plus, why not just crop the FX version of the shot in post production and call it a day? What changed things for me was the potential of AI resolution enhancement when I needed it. If, for example, I used Photomator's Super Resolution enhancement, I could enlarge that 10.6 MP shot to 6147x4095 pixels, essentially the same size of the FX version, with no noticeable loss of detail. In fact, sometimes the shot looks better. Having this capability in my back pocket allowed me to reconsider DX mode. I could now frame the picture the way that I wanted as I was shooting. And I was recording half as many megabytes in the process. Essentially, I was getting 600mms for the price of 400. For those of use with higher resolution full frame cameras - 40 MP+ - the equation makes even more sense. Examples of cameras with cropped sensor modes Sony full-frame cameras including the A7 III, A7 IV, A7C, A7C II, A7R II, A7R III, A7R IV, A7R V, A7S II, A7S III, A9, A9 II, A9 III, A1, and FX3. Look for the setting called Super 35mm or APS-C mode. For example, the Sony a7R V with a 61 MP sensor yields approximately 26-megapixels (6240x4160) when using APS-C/Super 35mm mode (1.5x crop factor). Nikon full-frame cameras including the Z6III, Z6II, Z7II, Z8, Z9, D850, and D780. The Nikon Z7 II with its 45.7-megapixel FX sensor provides 19.5-megapixel images when using the 1.5x DX (APS-C) crop mode. Canon full-frame EOS R-system cameras including the R1, R3, R5, R5 Mark II, R6, R6 Mark II, and R8 have a 1.6x crop setting. For example, the Canon EOS R5 Mark II offers a 1.6x crop mode that produces approximately 17.5-megapixel images (5088x3392). Panasonic L-Mount cameras such as the Lumix S5II/S5IIX, S1H, and S9. The Lumix S5 II utilizes a 1.5x crop factor in its dedicated APS-C mode, reducing the 24.2MP sensor's active area to an effective resolution of approximately 10.7MP (3984x2656). Cameras with fix-mounted lenses High-resolution fixed lens cameras, such as the Leica Q3 and the Fujifilm GFX100RF use crop-sensor technology to provide additional focal lengths from a single optic. The Leica Q3 with its 60MP sensor allows for cropping to 35mm, 50mm, 75mm, or 90mm. The Fujifilm GFX100RF takes this even further with its 102MP, 44x33mm medium format sensor. The fixed 35mm lens provides a 28mm equivalent field of view. Its high resolution allows for significant cropping, yielding 66MP in 35mm mode, 31MP at 50mm equivalent, and 20MP at 63mm equivalent. Final thoughts Photographers with full-frame sensors who don't always need the highest resolution they provide can extend the reach of their existing telephoto lenses, or travel with lighter optics when switching to crop sensor mode. It's not a choice for everyone, but for those willing to exchange pixels for reach, they can travel with smaller, more flexible lenses. As for me, with my Nikon Zf, I'm going to continue stretching my 28-400mm Nikkor zoom to 600mms when the occasion calls for it.
