Thanks, philber. I appreciate it! I've been lurking for quite a while and trying to learn from the great discussions in this thread. It's a nice, calm, encouraging community and that' so rare online these days.
As for the Rokkor-X: I found it at an antique shop for a mere $20. That's less than the price for the fotodiox adapter! I can definitely see a difference using this lens in comparison to the kit lens.
I'm getting the hang of manual focus on the NEX-5N, and have been fooled a few times already. That's part of the learning, of course. As I learn more and read more in this thread (I'm only half way through) I see I need to try some of the other modes. I'm primarily using A mode, but will try others.
Xbarcelo, love your G 45 and kit zoom pics!
Michael, your flower that is almost "hatching" is a delight!
As is your shot, Bob, so casual and effortless!
And, Jim, without your fine pic, I would have definitely thought Steinheil München to be a fine Bavarian beer
