My 24-105/4 IS arrives tomorrow. I tried a friends lens the other day with my 1d mark III, handheld, relatively stable, static subject/portrait, and I swear without IS the image was much sharper than with IS. Is this me or what, I had a TV a 250th with at 70mm so I should of been ok.
Also any general tips for using IS would be appreciated (other than use it in low light...duh).
The only problems I have heard of are when used on a tripod, but I haven't experienced any problems with my own version of the lens. I use it all the time, and the lens produces sharp images. Maybe it IS your imagination.
I think you'll like it.

One tip is to be sure to half press enough in advance of shot time that the IS system can "stabilize".
I find that if, for example, I just mash the shutter release all the way (there having been no shutter button press for several seconds), I often get a blurred image.
On the EF 24-105 f/4 L IS, it seems as if the IS system only stays alive for about 1.5 sec after release of the shutter button.
Ideally, the camera would automatically detect the eye at the viewfinder and, if IS was enabled, activate it. Having the half-depressed shutter do double duty for activating IS and controlling auto focus/auto exposure is a bit of an overload, and I expect that's why it keeps running for a second or two after you release: so you can choose an alternative focus/exposure point without losing IS.

The IS is a function of the particular lens used and does vary. Older IS lenses could not detect when it was on a tripod and had to be turned off manually or risk blurring the image.
