Review: Canon EF 85mm f/1.8 USM Lens


The Canon EF 85mm f/1.8 USM Medium Telephoto Lensis a moderate weight (15 oz), very well built lens. It does not come with the appropriate hood, the Canon ET-65 III. You get both a lens cap and a mount cap, all packed inside tight conformal foam to protect the lens during shipping. There’s also a very brief manual and the usual warranty paperwork.

The lens offers AF and manual focus, and allows manual focus even when AF is set to on, a very useful feature for low-light and other challenging focus situations. This is a USM lens, and as a direct consequence focus is fast and precise, just as you’d expect.

The AF/Manual switch is in a reasonable location, close to the camera body. There is a range indication on the barrel of the lens behind a transparent window which serves to keep dust and debris out of the workings of the lens. Manual focus is controlled with a broad, easy to manage textured ring about mid-body on the lens. During focus, nothing external on the lens body moves or rotates, so there are no complications for using polarizing filters, and no concerns about the lens “pumping” air and so causing dust contamination in either the lens or camera with use.

Once you’ve read and understood this post, you’ll have a perfect understanding of reach.
