Good points, P.J. People seem to like the 14mm f2.8 on all brands (and they have to focus also). I'd be using it 99% of the time at infinity (although I realize that with most lenses today, infinity isn't a stop at the end of the focusing range, so it requires focusing also). Regarding distortion,

Normally, I dislike seeking opinions on This vs That, because I figure one should do their own research and not "outsource their brain" on such matters. However, on this one I've done my research and I'm still torn. I would be using this lens for night sky stuff (aurora, meteors, mostly). I live at
