As the title implies, im looking at swapping my beloved 70-200 f/4L IS for its f/2.8 non IS cousin. How many of you have done similar? Did you find yourself missing the IS heaps or was it ok? I have turned the IS off to try get a feel and think i'd be ok, but with the added weight im not so sure.
I am keeping my eyes out for a 2.8 IS mk I, however, the mk II is way out of my budget so please dont suggest it.
Any thoughts on this?
