Just bought a 300D with kit lens. Pretty much total newbie in DSLR world, though had digitals for several years, incl. nice Panny FZ3, and used to have a Sigma SA5 a few years back with a big 400mm lens which worked well. So, keen, but know nowt and need help!! I'd like mto make it a real hobby now I have more time.
Anyway, need a zoom ... budget up to £200/US$400 and happy with new or VGC second hand. Age not an issue. It'll be used for wildlife and birds mainly (95%) and primarily in Africa and Australia. Probably not too big/heavy would be best, if possible.
I am thinking maybe 300mm would do but 400mm would be great if I can find one. I appreciate zooms are 'bigger' with this camera
Needs to be very decent quality, but clearly not top notch due to budget constraints. Decent resale value is an issue as I'll probably get a top notch lens in time.
I am thinking of the Sigma 70-300 APO, Canon EOS EF 75-300mm f4-5.6 AF, 400mm f5.6 SIGMA HSM and Sigma 135-400mm f4.5-5.6 APO, but this list primarily based on what I have found on second hand market so far. Any user experience of these would really be helpful. I guess the Sigma 70-300 APO is a safer bet as would be new.
Any suggestions very welcome 
Nice sugestion for future tho'.
Must be nice having money to burn.
