So I had to have another session without my DP1. My 28mm and the 70mm made me proud and the quality was as expected. The full size is all available over at flickr.
Once more I used one light, you even see it bright and clear including ME in their eyes. Aperture differs quite a lot in these shots from f3.2 to f8. I did notice that the 28mm sharpens up quite a lot with aperture. Sweet spot around F8 as normal, but this one really becomes VERY sharp at f8. Most of these shots are done with the 28mm. It’s my favorite studio lens. (I wish I had the 20mm and the 24mm as well).
