I just switched a bad copy of a 24-105mm F/4L lens for a new 70-200mm f/4 L lens in the last couple of days. I also bought a new 7D. I was getting much sharper pictures with the new lens, but there were times when even the pictures from the new lens looked soft.
Tonight I was shooting pictures of a bag with text on it.
Approximately 15 feet away.
Shutter Speed used was 1/60 and 1/250 @ f/4
In all shots taken the pictures are very sharp with no image stabaliztion and very soft (comparably speaking) when I turn it on.
So my quesion is, is there ever a situation where the image stabalization is more detrimintal than helpful? I have never heard of a case except on lenses that cannot be tripod mounted with IS on. I am hand holding in this case for all pictures.
Any information / knowledge would be very helpful. I'm going back to the dealer again tomorrow but this has gotton completely out of hand. One bad camera and two bad lenses. Maybe I'm not suppose to take pictures. lol
