It's hard to comment on individual photos because there's just so many, but they look like a nice set overall. I especially like your hollywood sign pic, and the one with the marina with the mountains in the background. What lens did you use for that shot?
Guess I got carried away huh. To anwser the question about the lens.... Most are shot with a Canon EOS Rebel XTI Camera with EF-S 17-55 f/2.8 IS USM lense But the shot your talking about I used a EF 75-300mm f/4-5.6 III lense
