I know that Canon lenses fit on Canon, and Nikon on Nikon, but I'm not exactly sure what mounts are and the EF-S etc. I have a T3i Rebel and I've had my 18-55 f/3.5-5.6 for about two years and recently switched the new 50mm 1.8 STM, and I love the switch. I'm considering about purchasing Canon's pancake EF-S 24mm f/2.8 STM to kind of get a wider angle, as well as using my 50mm f/1.8 for it's focal length. By the way, will that specific pancake lens work on my Canon T3i? Thank you so much to the answer who thoroughly explains mounts, EF-S, what lenses fit on which bodies! :)
