24-70 2.8 L lens
Is there a sweet spot when it comes to aperture on this lens? I know for zoom, its around 40-45mm

The 70-200 f/4L is considered by many to be the sharpest lens in the L series lineup and I can say that I don't disagree. It is tack sharp throughout the entire focal length with no exceptions that I can see. That is if you do get a good copy I know quality control has been in flux throughout the years...

I have been hearing the same exact thing. re the quality. I would only use the 70-200 outside, so I think I would be OK with F/4 - and I have also heard that the quality is not as great - been hearing whispers about the 50D as well, with noise issues. Have you had that problem...

You have the 50D...aren't you happy with it? Big step up from a XTi.

Digital Picture 24-70 Review
Hope that helps. I'm kind of dissappointed to hear that you guys are having problems with soft L lenses. Being a minigearhead I kind of had my list of wants planned out. And next was either the 24-70 or more likely the 70-200 2.8. =(Canon XTi: 50/1.8, Sigma 18-50/2.8, Canon 24-70/2.8L

my 24-70 could be sharper IMO. The 50D gets noisey in the shadows at ISO 400, it might just be my exposure settings tho...
but if the light is really good, I hardly get any noise. I am gonna have the camera look at in JAn after the busy season...and same with the lens. But I will say that my nift fifty is pretty dang sharp, and it fell down a mountin and I had to "pop"it back in place so it would focus...so I am sure my 24-70 needs some owrk also...

The 50D has micro adjustment...have you tested to see if the 24-70 is front or back focusing?
