I have recently bought Canon 80D. OMG talk about getting a payoff. The kit I purchased was the 18-135mm lens kit. Currently I have the following lenses: *Canon EF 50mm f/1.8 II *Canon EF-S 18-135mm f/3.5-5.6 IS USM (Kit lens) *Canon EF 70-200mm f2.5 USM L Canon EF-S 18-55mm f/3.5-5.6 (Kit lens from the 20D) *Are the lenses I pretty much use. The others are just left overs and not used due to crossover by better lenses. Which will be best for Canon 80D?
