in summer I´m going to Spitsbergen to shoot
polar bears. I use the new Canon 1ds II - and
am thinking of buying a super tele for it -
I just have a 100-400 and 70-200 (both IS and L)
and the two extenders (1.4 / 2.0).
So can anyone with close experience recommend
me a lens? I am considering the three lenses
(but of course only one can be bought!) -
the 2.8/300, the 2.8/400 and the 4/500.
I am tending towards the 400 but its very heavy
and the most expensive one.
Thank you very much,
