Summary: I like the lens a lot, it does what I wanted it to do, more or less for the price. The focus ring is really loose, which I like as I do a lot of handheld and need quick easy adjustments as I move or the wind blows.
Summary: Overall, it will improve my photography. My main purpose is for wedding jewelry, and close-ups on newborn feet, hands, ears, noses, etc. I played around with it after I received it last night, and as many mentioned the automatic focus was very loud, and seemed clunky.
Outstanding value for a tack sharp lens across a wide range of stops.

Summary: used every day in our professional studio for commercial photography. Price is excellent. Image quality is tack sharp across a wider stop range than the Sigma 50mm macro. The Sigma goes 1:1 and is also tack sharp but not across as wide a stop range.
Summary: This is an ideal lens for my need and by my standards. My need is for a walk-around lens with macro capability and excellent optics. My standards are impeccable handling characteristics, obvious structural strength, proven durability and absolute precision.
Excerpt: I love this lens because its short and compact. Theres no image stabilization, but for me IS is only needed when going less than a 1: 2 lifesize ratio. I can tell no difference in picture quality between this lens and the 100mm macro L lens at 1: 2 lifesize ratio.
Excerpt: I bought this lens for use in my still life studio, intending to use it for subjects that fit within an area of between 2 and 5 square inches. I've been using an older Canon 100mm macro lens that has given excellent results.
Pros: Consistent Output, Lightweight, Low Cost, Very good Image Quality
Summary: Beautiful pictures with my Canon Rebel T3i. The only issue I have with it is that it creates a lot of noise with auto-focus, and often takes a long time to focus. It has a lot of difficulty with focusing at sharp angles and at close distances.
