good point, by then diffraction is already killing away lots of the L advantage although on the other hand f/13 means a lot more diffraction for the 55-250 so it's not fair to that lensm yeah a mess a testIf you are going to show a test of lenses at least have the same settings. One shot is f13 and the other as f10. That way you can compare apples to apples. Second, nobody buys a f4 or f2.8 lens to shoot just at f10. Show a shots of both lenses at f5.6 and report back to us.
taht saidm, I think it's pretty easy to see a ton more crispness and details in the roof tiles with the L shot there, but f/13 to f/10 is a bad place to compare, not fair to the non-L at all to be given more diffraction to deal with. and even if both were f/10 that stopped down will kill off some of the L center sharpness advantage
