Hmmm, now I seem to think the problem is with something I'm doing... took this picture today and it came out nicely in terms of the problems I was having before:

I am using the lens on my Canon Digital Rebel XT. My Canon 70-200mm L lens works fine, as does the kit lens (well, as good as that one works). I don't have another camera to test it on, but i tried it again right now and it's doing the same thing. The pictures look GREAT when I look through the viewfinder, but when they are previewed, they are blurry and out of focus as the flower picture I posted up there, and the edges of all contrasting colors are blurry.
Picture Info:
Shutter Speed: 1/100
Aperature: 2.8
iso: 100
Metering: Pattern

And yes, I tried the lens with both the UV filter on and off. The quality was the same.

Are you using the lens at the 75mm end, if so at a shutter speed of 1/100 its possible that you are moving, when pressing the shutter.

I would personally mount the camera on a tripod, if you have one and fire off some test shots and/or shoot some shots at a higher shutter speed, raising the iso if necesarry. Hopefully then you will find out then if you have a bad copy or whether it may be your technique with this lens.
Dont trust the preview screen on the camera too much.

Thanks, everyone! I tried everything to no avail... the lens ended up being faulty. I exchanged it for a new one that is simply WONDERFUL. Now, time to get cookin'! ;)

I previously posted this.. but still like it.. .so a repeat!

My parent's dog geting her moment of fame.

This picture was extracted from the RAW file by Canon EOS Viewer. ISO 100, f3.5 at 1/100 sec, Exif lists the focal length as 59mm

I've cropped out part of the picture, and "blushed over" the phone number on her tag using photoshop elements. No other post processing at all.

I've resized this 50% to display in the post, but 100% scale crop is available here (external link)
