I have the lens, and I believe the noise is normal- it means the IS is on and working. And the jumping in the viewfinder is the IS in action, (if you wave the camera from side to side while focusing it should do that) I'd say no worries. It's truly an AMAZING lens. -Matt

So basically what canon is telling me is to, upgrade. Thanks A LOT GUYS

Does anybody know for sure if this lens won't mount to a 10D? AND, if Canon has any wide lenses of this mm coming out in the future that are compatible for the 10D? Thanks

Yea the contacts are PERFECT, it's BRAND NEW not used many times at all. I have tried it on other cameras, rebel, rebel g. I just don't understand about the IS, whether a screw is lose?

Thanks for contributing! -Matt

My 70-200 2.8 IS lens won't get on the proper aperture, it says 00

and sometimes starts at 2.5 and the image stabilization always

flickers. When my Elan 7e is off and i press down the shutter release

button the image stabilization just moves from side to side. I dont

understand why it wont work and I have never dropped it or anything

and now it just wont work.

I bought the lens from B&H and have had it for about 2 months now.

If you have any ideas to what the problem is or if if you think I

should take it to a local camera shop and have them check it out?

Thanks, -Matt
