Designs #87 and #94, while beautiful designs, lose the simplicity that appealed to me so much in #29. I really like #29 quite a bit, though it reminds me just a little of the Pittsburgh Steelers logo. ;-)
Design #83 is interesting, but I don't like that the outer circle has been broken... it just doesn't work as well. I would love to see some further variations of #29 that might bring 'craft' or other aspects of my photography.
Just in case you missed the note, I'm looking for a fairly minimalist icon that can also be used as a watermark on my photos. Lastly, I'd like the icon to work in very small 16x16 'favicon' format for my web site.
I don't like the lens hammer #141 at all. (Too violent, too much like a judge's gavel.) The others are interesting, and I'll rank them after I look at them some more.
I'm going to reject the 'rolling hills' that you've been playing with. They're beautiful and tempting, but they conjure feelings in me that aren't quite right.
