Does IS perform poorly in vertical position?

I recently had a chance to test out the Canon 17-55 f2.8 IS lens. I notice that when shooting in vertical position, the IS doesn't seem to work well, that is, the photo turn out to be soft. All the landscape shots are very sharp, without even paying attention on holding the camera still.

For both photos, the focus is in the middle of the green door:

Do you consistently get these results? That's the first thing to determine.

IS on a 17-55 should account for both axies of rotation... if it was mode 2 on older L lenses, then there would be problems... might just be a lack of a protrait grip


I don't hate macs or OSX, I hate people and statements that portray them as better than anything else. Macs are A solution, not THE solution. Get a good desktop i7 with Windows 7 and come tell me that sucks for photo or video editing.

I've heard of this problem with that new 75-300 IS or whatever it is.

the problem was with the 70-300 IS lens and Canon will fix the issue for you. I know if it has to do with IS or not, but I know they replace glass inside the lens. Mine has been fixed and its wonderful to use now!
