55-250 vs 70-200 2.8 at 70mm f/4
The point of my post is that the L lens can do things that the EF-S can not. Like shoot at 200mm in the rain at 2.8. That is one of the main things you pay for in this example.
I know that chart is not a real world example ad it will always very depending on what you shoot. However I know that wildlife photographers rarely have the light they want and that 2.8 comes in handy. Sports shooters need fast SS to stop action and 5.6 ain't gonna cut it at a sports game, IS or not.
I have heard that the 55-250 is a good lens and that it yields sharp results but I am curious as to how large you viewed your comparison pictures.
yeah like fit my cameras . when you get into specialized shooting like sports or wildlife enthusiasts use the best lenses they can afford.
