I'm impressed with the clarity,even with 2 teles.

Quoting Christian <[EMAIL PROTECTED]>:
Thinking about the latest thread on what lens for bird photography
without breaking the bank, I went out and did a quick field test.
Here is a 300/4 with 1.4x extender AND 2x extender for a total of
840mm f11 equivalent. I used a Sigma flash with Kirk flash x-tender
for a bit of extra light. The bird was about 50 feet away and this
is quite a crop and resized for the web, etc, etc. (It's crappy
composition; I hate the looking-up-perspective, but it's a pretty
bird: a Northern "yellow-shafted" flicker (Colaptes auratus) a type
of woodpecker common around here).

As a test I'm happy with the sharpness, color and lack of any obvious
lens artifacts. The combination of lens and 2 TCs was a bit
difficult to focus due to so much loss of light, but definitely
doable.
