Alright
I've got an old canon 400d body, and I'm off on safari to kenya at the end of the month. I've currently got a 10-20mm, and a 18-200 IS lens, both Sigma.
I'm thinking I could probably do with something a little longer for the trip - maybe in the region of 400mm. I don't think I'll have the option to use a tripod much, which means I probably need something relatively fast - will this completely eliminate the option of using a teleconverter with the 18-200mm lens?
other options (on ebay) appear to be an old 200-400mm tamron, a 400mm sigma (which only works on manual, f5.6), and that's about it without breaking the bank. Has anyone got any experience with these lenses, or have I misses something off the list?
