Hello again guys, Im so frustrated maybe u guys can help? I JUST got my EF 28-135 f/3.5-5.6 IS USM. I turned on the camera and started taking pics with IS and it doesnt seem to help. at an f/8 and 1/15th it is still blurry. I am a little depressed about this. the pictures are not that clear even with the IS off and on a tripod. Moreover, im really dissappointed at the noise the IS makes. Im trying to decide whether to take it to canon (practically in my backyard) or return it and pay shipping for return shipping. Am i missing something about IS?
