SO dont get confused..Its easy to mistake this for the version with IS (image stabilization) because they can often be close in price, at least when it comes to used ones... This is actually a great lens and is probably killer for the Sony A7III and other cameras with IBIS, but NOT so great for Canon users, unless you are going to follow the 1/focal length rule and use this outside or indoors with strobes/flash.... Would be perfect to use for head shots, etc. where you want a fast shutter speed to avoid seeing pics of your subject with their eyes closed... Also good for say air shows, where you are going to naturally have a very fast shutter speed anyway.. Its super light and the focus and zoom rings are nice and smooth and focus is really quick.... Also, despite it "only" being F/4 its easy to get BOKEH...Have your subject as far away/close to you as possible to get the framing you want at 200mm (320mm on Canon APS-C) and make sure the background behind them/it is as far away as possible...Maybe your subject is 8 from you, but the nearest object behind them is 20-30 or more away... Color/contrast is nice, although not quite as nice as a 2.8 version, but those are at least twice as heavy and as much as 4 times as expensive! All in all, the cheapest (generally, check the 24-105 F/4 also) intro to Canon L lenses you can find..
