I'm already thinking about the next piece of equipment to get for my camera, and my 580EX hasn't even arrived yet. :P
I'm thinking I might save up for 70-200 f/2.8. I want to go for the f/2.8 cause if there's one thing I've learned this year, it's fast lenses rock! However I'm still unsure about the IS vs. non-IS. I own one IS lens already the EF28-135 USM IS. I find that I use the IS everyonce in a while. Though I know that most of the time I just want a faster lens to keep the shutter speed up. Going to a f/2.8 lens will be nice, but will I still need IS on this lens? There's quite the price jump adding the IS, so budget may dictate that I won't get it. However I'm curious how many people out there have the IS version of the lens, and how often do you actually use the IS? I'd likely invest in a monopod with the lens anyways, so that might be the solution to keeping the lens still and getting lower shutter speeds.
If anyone knows of a good thread in the archives regarding this issue you can point me to it as well. I'm sifting through them as I find time.
