I took my M10 this morning, and I used with it a lens that I hardly ever use. The Summitar 50/2 (second version with 6 aperture blades). I set ISO to 100 and the lens to 8~11 as we have lots of sunshine here. There were very few birds present this morning. I usually stay there about 20 minutes total. It was not a difficult task to undertake. I get more used to my M10, and I get the chance to try out some of my lenses.
I noticed that yesterday when I used the Heliar with a ltm-M adapter, the M10 would not let me use Live View with this lens. I would get "there is no lens used".
