Hi Everyone, I just started getting serious about photography last month, when I purchased my first DSLR, the Canon Rebel T1i with kit lens(18-55mm). I have been taking a lot of pictures with the it lens and a bunch with my friend's 28-135mm 3.5-5.6 IS USM. I was really shocked by how sharp the 28-135 pictures came out, compared to my kit lens. This prompted me to rent a L series lens (70-200mm 2.8L IS)just to see what the IQ was on it compared to the rest I have used. I was frankly a little shocked, since I read a lot about the 70-200 and how it is one of the most sought after lenses on the market. I honestly didn't see much difference in IQ from the 28-135mm pictures to the 70-200mm pictures and actually, I sort of preferred the contrast I got from the 28-135 lens. I went and read some reviews on the 28-135 lens and it is a decent lens, better than my kit lens but according to the reviews, should be lower than a L series lens. Please help, I don't know if it is me that is not using the lens properly or if I just went into the whole "L-series" testing with extremely high expectations. Set this green photographer straight about L-Series lenses. Thanks in advance everyone!
