100-400 or 400 F5.6 or 300 f4 IS

I have heard rumours of those two being upgraded. Possibly weatherproofing and IS for the 400f5.6 maybe better optics, possibly f4.How on earth such lens can get much better is open to debate. The optics of my current "L"'s is fine for me.


I think i will possibly flip a coin. Its the 100-400 versatility against the 400f5.6 image quality. Ive checked out the ISO charts and the differance seems small. I wont really need IS as ill be shooting birds at higher ISO and shutter speeds so wider apetures are more important. I looked at the other options and the 400 F2.8 and 400DO look excellent buys but expensive. The 500 f4 would be my choice if i had the choice, and he money.


Versatility and stabilisation against image quality.

The 400 f2.8 IS. As good as it gets in 400mm. If you got the bucks, go for it!
