<p>Thanks for the responses. Does this happen in traditional film cameras as well? I did not notice it on my old FE2. Maybe I just did not do experiment on film so I missed the effect. Just want to confirm that I can do nothing to avoid this with camera settings. Am I right?</p>

<p>I recently brought the Nikon D600. As a seasonal photographer this camera does good job for me, especially I can use all my AI prime lenses I used for my film camera. Yesterday I tested my old 35mm f/1.4 with the camera. Everything works fine except, when I use aperture f=1.4 I see dark corners, which, become less and less when I lower the aperture. The problem seems not there when I try other lens with longer range, i.e. 85mm f/1.4<br>

<br />Does anyone know the reason? I suppose the fx camera acts (in terms of coupling with lenses) the same way as traditional film camera. Why are there dark corners?</p>
