I've been offered a used Canon Telephoto EF 400mm f/5.6L USM in excellent conditions (don't know the price yet ... ) ... Any opinions on this lens from your experience? With a 2x converter how many stops will it lose? No AF I guess ...
Thank you,
Max

SMC2002 said:Pete is also correct about making sure you are serious before you attach this lens to your camera. Yes, it is that good

now I'm in a hurry, have to go, but ... I'll let you know if next morning will see me wiser than now ...
Should I really dare facing this lens? I'm already trembling (so does my bank account...)

SMC2002 said:I agree with Ian that 400mms is barely acceptable for birding. 300mms is just too short. Now, I have considered the same approach using the F2.8 300mm. A 2X TC does effect image quality, but not all that much on this fine piece of glass. 420mms @ F4 with a 1.4X and 600mms @ F5.6 with a 2X may well be worth the expense.

gmax said:Hi Steve, thanks ...
one more question:
Which budget TC is really compatible with this lens (and, in general, with an L-class lens, e.g. a 300mm f/4) apart from the Canon extenders? I'm not referring to AF limitations ... MF good could be good enough.
I've read a lot about these TCs, but things are not that clear: for example, what's the difference between these two: Kenko 1.5x SHQ DG and Kenko Teleplus Pro 300 DG 1.4x?
Thank you all
