Hey everyone. I'm pretty new to SLR Photography and so far, I only have 3 lens kits and I'm trying add another one. I'm looking for a lens that has some good zoom capabilities. So far, I've come down to only a few options. Lens 1: http://www.amazon.com/Tamron-28-300...ON8I/ref=sr_1_8?ie=UTF8&qid=1333918279&sr=8-8 Lens 2: http://www.amazon.com/Canon-55-250m...1?s=electronics&ie=UTF8&qid=1333920166&sr=1-1 If anyone has any other suggestions please feel free to list them. My current Lens kits I have: Canon 18-55mm Canon 50mm EF f/1.8 Canon 28-135mm USM Thanks for the answers in advance.
