i have a canon 550d with stock 18-55mm lens. sometimes i would like a bit extra zoom.
i dont need one of the super duper quality lenses but i would like to upgrade my stock lens to a slighly better overall walk around lens.
the two i though i would go for is the 18-85mm or 18-135mm.
i have found a second hand 18-135mm for $300. is this a good price and is it worth upgrading to?
