In this focal range, none of the black ones I am afraid....not even
sure about the smaller white ones like 300/4 and 400/5.6....the (-I
think necessary-) fluorite elements are only included in the class of
200/1.8, 300/2.8, 400/2.8, 500/4 and 600/4....
Which is one more reason for me to desire a 200/2.8 with image
stabilisation....:))
(the zoom-IS'es are no good for me, they are too large to store
upright in my PhotoTrekker, while the 200/2.8 does fit that way
(barely))
I once even considered a Leitz 180/3.4 or 180/2.8 APO, with a
Leica->EOS adapter, for this reason only.
Anyone have a confirmed list of high end EOS lenses which, per
manual, state that no IR-correction is needed?
Not sure whether Canon service will like me if I order manual-copies
for all these lenses....:))
