Excerpt: This is a great light weight lens. I'm giving it three instead of five stars because of build quality. Optically this lens is amazing but it doesn't inspire the confidence of a professional lens like the L series does.
Pros: Consistent Output, Fast / accurate auto-focus, Lightweight, Nice Bokeh
Excerpt: The first copy I received from B&H was definitely too soft and called for a replacement. My second copy is much better but I do not agree with many of the reviews I have read on this lens. The lens struggles to focus in low light and under the best circumstances it is not tack sharp.
Summary: I had high expectations for the Canon EF 85mm f/1.8 USM, but it disappoints. I love the distance for portraits and that it's a prime. It's fast and sharp, but it leaves chromatic aberration in almost every photo. I've used it on two camera bodies and always with a hood.
