I apologize if this topic has been discussed. Search option has given me too many results. I am a beginner in photography. I began shooting when I first purchased my Canon Kiss X2 (450D/XSi). I currently own a 50mm f/1.8 II and 75-300mm lens as a starter. I wanted to expand my shooting so I was wondering if it is better to get the Canon EF 28-105mm or Canon EF 28-135mm? I am working my way up to purchase a lens but I am not sure which one to get. I was wondering everyone's reviews and thoughts between these two lens.
