Like I've said i the other posts, please don't take these images as a real test of this lens capabilities. By that I mean they were taken on a very quick walk through some woodland without much though process behind it. If you like, just call them snaps and have done with it.
The lens does focus very quickly with the G5t, I haven't tried it on any other camera at the time of this post. I might do that at a later date, or I'll just leave it altogether because the older cameras do NOT focus as fast as the G5.
