This one from the FA 31 f1.8 I like a lot. The sun shon through the leaves to where my wife stood illuminating just her face. I hadf to be quick on this one as it didn't last long, just a few seconds. I was quite surprised how the focusing seems to be bang-on. Practice makes perfect.
I'm going to be trying these lenses out on the Sony-5N pretty soon. I think I'm going to like the result.
