Ok all you pro's. I need some help, I just received my 28-300L and its not as impressive as I expected. In fact I think the clarity and consistency is equal or better with the 100-300 USM. I am trying to justify keeping this thing but now I am very confused. I have taken several test shots and the photos are equal on screen. Where should I be seeing the major differences? Also when I turn on the IS and try to AF it makes a hollow clank inside, normal or not? I don’t hear it on my 28-135 IS as loud.
I will say it focuses faster and I like the fact I can be about a foot away and use the total range of the zoom. But is it really that much better?
Thanks in advance for saving me money or making me feel comfortable with my purchase.
