  1. Hi there, thanks for all this advice. Just a quick response to your questions, yes - I shot in manual. The light was constant and was just natural light from the window. I sat my bottom on the same spot, camera same distance to subject with same focal lengths on both lenses, so the variables pretty much didn't change. I think good advice is a series of test shots, especially at different apertures, I will do that as I had not thought of it. Hopefully I can close this thread with some good news that the issue has been discovered. Thank you!
  2. Thanks, however, it's my prime 50mm that's giving me the underexposure, so using my 70-200mm wouldn't make it a fair comparison. Am going to borrow another 50mm and see how this exposes...
  3. Basically the same as what I did in my test shot (images attached) - I had my D800 with me, took a shot of something in their repair room with my 1.8, they then gave me their 1.4, same camera and settings, and same image, and the exposure was the same as my lens... that's the bit I don't understand. And the exposure was fine, btw. whereas in my sample images it's underexposed.
  4. Was thinking the same - I only have a 70-200mm which won't work for this exercise, but I can borrow a more suitable one from the place I hire kit from that I don't have. Will do the whole round of experiments on both cameras... Thanks Mary.
  5. Well, that we know, right? :) I'm thinking maybe my 24-70 overexposes?? But I always felt the images look correctly exposed with that lens... the mystery continues...
  6. Many thanks for that. I have two cameras though, and this happens on both my D800 and D600! So couldn't be the camera, right?
  7. I have a Nikon 24-70mm and Nikon 50mm 1.8 lens; when I shoot with these lenses on the same camera (D800) same settings on the camera for both lenses (e.g. f2.8, shot at 50mm, 1/100th/s, 500 iso) the exposure is vastly different (50mm prime underexposed, 24-70 exposes brighter. Took this to Nikon repair store here and they compared my 50mm to one of their prime 1.4 50mm, and the exposure was the same, so doesn't seem my prime 50mm is damaged... why does it do that? Is that actually normal?
