I have two lenses for my 300D. One is the standard 18-55mm and the other is the 75-300 zoom lens. The 75-300 is only ok but I want more long range zoom, Is there a better Canon or compatible 300d lens out there?
The Sigma 120-300mm f/2.8 is good and so is the Canon 24-105mm f/4L IS. The cost to upgrade from your current lens arsenal is about $3000 USD. With regards to camera lenses, you really do get what you pay for, and you don't get much for $150.
