daacon - I'm glad you like them and that they brought back some fond memories. My husband used to work in the aerospace industry (Boeing) and has always been a huge fan of fighter jets and other planes. I can't help but be awed by them myself.
Steve - I used my K100D with the Sigma 70-300mm F4-5.6 DG Macro lens. As far as I know, it was probably completely wrong for the job, but all of the camera jargon is completely foreign to me. I finally realized the other day just why understanding photography is so difficult for me: It's the numbers! I have always been averse to math of any kind, and the numbers in photography completely confound me!
