I recently acquired this lens, a Sigma 400/5.6 non-APO and would like to know a couple of things about the camera settings.
I realize this is a "manual" lens (the camera is requesting focal length input) and I did go over (this happens to me all the time with such lenses) the Sticky Thread on using manual lenses, I am still perplexed.
Edit: Is this really a "manual" lens in the sense that there is an "A" setting on it???
1. The camera is set at M (manual) mode. K20D or K7.
2. The proper focal length is input.
Each picture taken shows that it is at f 5.6, no matter what I try.
Is there any way that this lens can be stopped down?
Thanks in advance for any tips.
JP
