Nikon fx1/20/2024 If not obvious by now, I would add to the above that I would consider using DX lenses on an FX camera as a temporary solution only, until you save up enough to buy some dedicated FX lenses to go with your camera, otherwise the drawbacks almost outweigh the benefits. They use similar (but not identical) sensors. Incidentally, both the Nikon D850 DSLR and the Z7 mirrorless camera are 47MP. Plenty of people have tried to override that restriction, and I am not aware of any way to do so. The Z6 and Z7 will not capture the entire FX frame when you mount a DX lens. On the FX Z6 and Z7, they will force the DX crop if you mount a DX lens. On Nikon Z mirrorless bodies, the Z50 is DX to begin with. Auto switch between capture FX or DX, depending on the type of lens mounted, FX or DX.Always capture the entire FX frame and let it vignet and the quality degrade toward the edges.On Nikon FX DSLRs, there are photographer selectable options on how to treat FX and DX lenses. In certain focal lengths, some of the DX lenses may appear to cover the entire FX, 24x36mm, frame, but image quality outside of the 16x24mm area may be fairly poor, and it gets worse farther away from the center of the frame. Nikon DX lenses are designed to cover the DX, i.e. You are not getting the use of the entire FX sensor, which to me is the reason for going from DX to FX. If you run a FX camera in DX mode, why even upgrade to FX? THIS is one of the major concerns of upgrading from DX to FX that you likely have to replace ALL your DX lenses with FX lenses. This seems to be lens specific, some do, some don't, some will have vignetting at one end of the range and less/none at the other end, some will wide open and less as you close down. This means that on a FX camera, the image will be vignetted in the corners, so your usable image rectangle will be smaller. #3 The DX lens will generally (but not always) have a smaller image circle than the FX lens. That depends on WHICH FX camera you select.Ī D750 at 24MP has essentially the same resolution as your D7500, but a D850 at 36MP has more resolution, and a Z7 at 47MP even more resolution. Same lens on a FX camera will give you less magnification and a wider view. If I used a DX lens like a Samyang 8mm, Tokina 11-16mm, Nikon 35mm, Nikon 18-140, or Nikon 70-300mm on a Nikon mirrorless with converter:įull frame is full frame, it does not matter dSLR or mirrorless, it is still a 24x36mm sensor.ġ00mm lens / 35mm DX normal lens = 2.9x magnificationġ00mm / 50mm FX normal lens = 2x magnification. Would vignetting occur on all DX lenses, or just certain lenses at certain focal lengths?.Would the megapixel quality be the same, less, or greater than on my Nikon 7500?.Would I get the same photo view as I would on my Nikon 7500? (i.e.If I used a DX lens like a Samyang 8mm, Tokina 11-16mm, Nikon 35mm, Nikon 18-140, or Nikon 70-300mm on a Nikon full frame: I'm a little confused about what I'm reading (and have read some contradictory claims). ![]() I've been thinking about upgrading to full-frame or mirrorless at some point, so I've been reading up on lens compatibility. I have a Nikon 7500 and a bunch of specialty DX lenses.
