This video is for both Beginners and Intermediate Canon Users.For Beginners (we advise you to take notes):We are going to make sense of the 5 types of Canon
Lens adapters come in two forms: those that fit between the rear of the lens and the camera body, and those that attach to the front of the lens. The ones that go on the front are concerned with enabling a lens to focus closer than usual, but there’s a greater variety of adapters that attach to the back of the lens. Read more: Best CanonFocus. Can focus to infinity. Canon EF 75-300mm F/4-5.6 III. Canon EF-S 18-55mm F/3.5-5.6 IS II. Many lenses allow you to focus to infinity. This is essential when you wish to take photos including far off objects, such as when shooting landscapes, in order to make sure everything is sharp and in focus.
This won't change with the speed booster. The 32mm is a better quality lens. That said, if you want to get more EF lenses, then in the long run the adapter may be better. The 18-150 should be of similar use to the EF-S 18-135mm, which is already a pretty good lens ( not compatible with the speed booster, only normal adapter).
All EF-M lenses to date, including the EF-M 32mm f/1.4, utilize a stepping autofocus motor (STM). The 32 f/1.4 uses a lead screw-driven (vs. gear-driven) STM system that is very quiet, producing a light "zzzzzz" with some clicks that can be heard in a quiet environment. Autofocusing is smooth, ideal for shooting video.
