How much are you dying to get your hands on a 5D Mark II?

Yes, Canon does need to update their 24-70 f/2.8 to include IS. I think it would be a hugely popular lens. Maybe they're afraid it would be too popular and replace many other lenses in a photographer's gearbag as it would be the ultimate primary lens. Could the reason we don't have a 24-70 f/2.8 L IS lens purely a marketing decision? I doubt there is any technical reason why we don't have it...

It might also have to do with the design of the 24-70 f/2.8, which by many accounts is a stellar lens (I haven't had the opportunity to use one in the field yet). You can't just take an existing lens and plop in an image stabilizer...it requires additional lens elements and the circuitry takes up space. Adding IS to the 24-70 f/2.8 could quite easily have detremental effects on the image quality.

Daniel...that is a super helpfull discription of a full frame advantage that i never thought of. I am a wedding photographer and have been hesitant on upgrading to the 5D mk II, but the low light capabilities with a 24-70 2.8 vs my 50D with the 17-55 2.8 are very convincing.

Thanks, you are very welcome.
