Q: 1. How's the corner to corner sharpness?

A: It's not too bad when it's stopped down, but it's not as good as a prime (obviuosly). For stills I use a manual focus voitlander with adapter. I got the 21 converter for video---the autofocus is nice. I'd use it for stills in a pinch. If you are into landscapes or architectural photography, this isn't what you want.
