Re: Canon 70-200mm F/4L USM with or without IS?

I have the non-IS version and I am going to move to either the IS f\4 or IS F\2.8.

You have a APS-C camera, so at 200mm you are at a 320mm equivalent FL. For off tripod shots at 200mm indicated on the lens, you will probably want your shutter speed to be at 1/500 or faster. So, take a look at your shooting conditions, what ISO do you need for f\4 and 1/500? is that going to work for you? If you have the IS version you can go 3-4 stops slower - three stops would give you 1/125 shutter speed, or you could back your ISO down.

Both lenses will give you great IQ and sharpness, it just depends on how much light you have to work with and what look you are trying to get. The IS version gives you some more options, but costs more.
