Big difference 70-200 IS f4 or f2.8 II ?
Jun 18, 2010

Hello,

I am agonising about the question which telezoom to buy for my 7d:
70-200 IS 4.0
or
70-200 IS 2.8 II

I know according to the reviews the 2.8 is much better than the older version. But how does it compare to the 4.0 IS on a 7d?

Is there anybody who can coment on this?

I am thinking to use one of them with the TC 1.4. Will there be a big difference in focusing speed?

Thanks
Franz
