Oh those throwing! Take EF-S 17-55 or EF 17-40 L, yellow ring or red, F2.8 or F4, with or without a stabilizer, without or with moisture protection, with or without a trunk. It's simple . when there is still FF, then such a question did not arise. Different pros: - Quality of performance. Maid in Japan and that says it all. Looks solid and good. - Bought for crop 77D, to replace a staffer, got up like a native. - Lighter staff. - Autofocus is just a bullet. Practically does not smear. Although all experts unanimously say that taking an elk for crop is not comme il faut, all this is garbage. Before buying, poyuzayte, drive, try to fit your needs. Take your camera to the store and try the lens for your tasks. I was pleasantly surprised by a 40 mm bokeh, I thought that it was unrealistic to get such a thing on a clean landscape, but it gives out. Cons: - No stabilizer. If there was one, everyone would buy it. - Filters for 77mm are not even very cheap, I bought a strangled toad for 3200.
