I have been into wildlife photography, mainly birds, for around a year now and have had great fun learning the ropes with my panasonic "bridge" camera. I am starting to get a serious itch to get a DSLR now, and hope to scratch that itch if funds permit sometime early in the new year. As far as the body goes i would probably get the Canon 500d, or if i'm feeling affluent the 50d.
My main question is about lenses, in an ideal world i would like the Canon 100-400 USM L lens, however this lens costs around £1300.
The more realistic option is the sigma 150-500 IS HSM lens, and at £698 it offers seemibly great VFM and a longer focal length, i could buy this lens plus the canon 500d +kit lens for less then the price of the canon 100-400 lens alone!
So my question is this, If a buy the Sigma lens am i constantly going to be wishing i'd saved the extra for the Canon? Is it significantly better then the Sigma?
Many thanks, James
