The results are actually quite surprising.įirstly, the vignetting is definitely an issue, but you can mostly correct for it in Lightroom. I would still use f1/1.8 in certain circumstances, but none of the images in this test were wide open, because I wanted to judge sharpness too. For the simple reason that this lens fringes significantly at F1.8 and is a bit soft wider than f/2. I mostly either went between f/2.8 and f/4. In my shooting tests I kept the Aperture f/4 or wider. I’m guessing it’s probably in a similar place on other FX Nikon cameras. On the D700 the option to turn off the Auto DX Crop is in the shooting menu under “Image Area”. Anyway, I had messed around with it for a bit, and then promptly forgot about the experiment until last week when I saw a post from Jared Polin who was comparing the old DX lens to Nikon’s new 35mm f/1.8 FX lens, and I thought that I’d give it a proper try.įirst of all, you need to turn off the Auto DX Crop. After about f/4 to f5.6 the edge of the image circle starts to come into frame and there’s nothing you can do to compensate. It only works when the lens is kept fairly wide open. ![]() I went home that day and tried a few tests, and sure enough, with the DX Crop mode turned off on the D700, the 35mm DX lens still captures a full frame image, albeit with some pretty harsh vignetting. This piqued my interest because I have the same lens but I’ve never tried it on my D700 because cropped it would only be about 6mp, but It had never occurred to me that it could be used with the crop mode turned off. ![]() In his set, he also had a few pictures that he had taken with the DX crop mode turned off, and they were mostly ok, apart from some severe vignetting. Because of the sensor resolution on the D800, even cropped you’re still getting a fairly large image. About a month ago I was having coffee with a friend and he was showing some pictures he had taken with his 35mm DX lens on his D800.
