So I was planning on getting the 60D with the Canon 18-135mm f/3.5-5.6 IS kit. However, a friend offered to split the costs if I got the 18-200mm f/3.5-5.6 IS kit instead. He is willing to trade his slightly used 28-135mm f/3.5-5.6 IS USM for the 18-200mm. I've heard so many great things about all of these lenses and I'm torn on what to do.
Since this is the first time I am going to delve into the world of photography, I've decided to turn to the experienced members on the board with a few questions! Is this a fair trade? Should I just stick with the 18-135mm or the 18-200mm?
