Hi Forum,
I have a (silly?) question: about two month ago, I bought the Canon Eos XTi with a Sigma 70-300APO DG Marco lens. So far I'm quite happy with this equpment. But now I want to go to an National Park (Banff) and I'd like to capture some animals (if possible moose, chipmunks, maybe bears...). The Sigma lens is really good to take pictures of squirrels from a distance of about 10-15 meters, but I don't really want to come that close to a bear or moose...
I looked around a little bit at ebay, and they sell 650-1300mm lenses for 230US$. This seems a little bit too cheap. Does anybody have experience with such a lens or could recommend a lens, that won't cost more than 500US$?
I also saw some teleconverters (2x, would mean 600mm * factor 1.6), how good are they?
Thanks for your answers,
Anja
