where's the sweet spot for a 24-70L?

I've been taking majority of my pictures indoor/home (moderate lighting) and find my XTI mated with my 24-70L to be excellent/tack sharp at f/5.6 to 6.3 with my 580EXII. I just find at f4 the images to be good but not tack sharp. No doubt all the pictures would be phenominal with a 5x7 print. The price of this glass makes me so concerned. I still have plenty of time to send it back to canon if this is an issue. My camera has been back to Canon already and has been calibrated so the camera is probably not a variable "if this is a focussing issue." or is this simply a sweet spot issue of my particular lens?

Is this due to my pixel peeping behaviour or am I just being unrealistic. My 70-200L truly appears to be tack sharp even at f/2.8 to 3.2 indoors with the same lighting. I'm just wondering if the small sensor in my XTI just cannot take advantage of the 24-70L.

The 24-70L has never disappointed me when outdoors. Perhaps this is just the fact that the quality of light is my issue for indoors.

TIA I appreciate any input.

when i go out to shoot with it, i primarily keep it within the f/3.2-f/5.6 range. i don't like shooting wide open unless i really need to, and i've found that stopping it down even slightly gives it a major sharpness edge. f/5.6 is sharp enough to cut your finger on, and i've never really found a need to go higher than that on a day to day basis unless i'm looking for really vast DOF or i'm shooting out in bright daylight. with the 580exii indoors, f/5.6 is probably what i'd offer as the closest the 24-70mm has to a sweet spot. i think if you find f/3.2 too soft, you're probably a pixel peeper that needs to seek some professional help. good luck! ;)

Sweet spot on my 24-70 is at 50mm @f5.6
But i'm using it mostly at f2.8 (that's why we pay a lot of money on 2.8 lenses, cause we need to use them wide open, don't we ? :) )

I find it to be fully usable at any aperture or focal length. Like any lens, it gets sharper as you stop it down to f/5.6-8.0, but still very usable outside that range.

unrealistic. the longer zoom is a sharper lens.

Most lens's are sharpest at one stop above there rated stop.

^ Actually, it's closer to two. So for an f/2.8 lens... f/5.6 would be sharpest.

Actually, it varies from lens to lens, so you'll have to figure it out for each one. :)

Yeah. The 70-200 f/4 is razor sharp at f/4
