Hi Folks!
I stumbled across this great forum a couple of days ago and wanted to get some pearls of wisdom...
I just got my 20D kit (w/ the 18-55 lens) and want to start seriously buying into the Canon line. I am in the position to spend $1,000-$1,500 for the first purchase (1+ lenses). I will then be able to buy more as I sell off my old system. (Manual Contax 35mm with Zeiss lenses)
My interest from photography stems from a fantastic trip to the Southwest where I took a number of landscape shots that looked good to me. Since then, my interest has been nature, primarily landscapes. I recently rented a 10D for wildlife photography in Glacier Bay and decided to convert to Canon. Eventually, I want to have a line of lenses to cover these subjects.
However, my immediate need revolves around taking pictures of my twins that will be born in the next month.
Considerations:
1. I read that the focus array works best with lenses with a maximum aperture of at least F2.8.
2. I am a stickler for quality.
Any advice you would have on a first (and following) purchase(s) would be greatly appreciated.
