Since I've made the switch to FF I've lost the ability to use telephoto lenses. :-[ I can't mount my 55-250 on there without some "modifications." I shoot RC car drifting with my 24-105 usually at the 105 end.

I have been looking at the 70-300mm USM as I can get it around $330 used in my area. Are there any good telephoto lenses around the $300-500 price point that I should consider? Thanks you!
