I currently use a 40D with a 300mm F4 IS and 1.4 TC and am very happy with the results that I get. However I would like more reach while retaining autofocus.
There seem to be three possibilities:
1) 500mm F4 - I've tried it, fantastic results but expensive and heavy (although manageable).
2) 300mm F2.8 + 2X TC - not tried, but this forum has lots of enthusiastic recommendations. Not so expensive or so heavy, but I already have a 300mm lens and it seems a bit of a duplication.
3) Buy a 1 series body and 2x converter and continue with the 300mm F4 - not as expensive as the 500mm and much more portable, but I suspect that the results will not be so good (Does anyone use this combination?).
All views / votes welcome.
Thanks
Tony
