Pros: Easily Interchangeable, Nice Bokeh, Lightweight, Fast / accurate auto-focus, Consistent Output Cons: Other thoughts: good product

Awesome lens, awesome price. Will definitely improve your macro pics.

Outstanding lens for macro work, but equally great for portraiture. Superb sharpness. Best to manual focus using a tripod for macro images. Canon is all I use because it's the best !

Canon Macro EF 100 L. fantasic medium tele lens, purpose built for macro, great as a medium portrait lens. This is one of the superior lenes in this class.

I must admit that this is one of the sharpest and most compact tele lenses. It's quite solid, feels well, it's fast, it's crisp. At f2 you can get a really decent result in a low light as well but of course it's a little bit soft at f2.

the 100mm f2 is a great lens, and pocket and wallet friendly

quick af; large apperture; good for sports and portraits

none really; slight purple fringing at f2

This is my favourite astrophotolens. And I use it with success photographing babys in low light situation. You can use in streetphoto without people realising you in fact are zomming in with a 160 mm equivalent mount on a 7D. Recommended!

A true gem! Sharp wide open.

Prone to flares wide open..

Purchased this lens for astrophotography. Color correction is good and stars are sharp to the corners when stopped a little.

Fast; Lightweight; Sharp across field

I've only used this for weddings so far, but LOVE it! It's great for low light ceremonies, and sharp images. This lens exceeded my expectations.

I no longer have this lens, but I really enjoyed it while I did. The quality it produces is really excellent. AF is very quick and responsive and it works great in low light. My only complaint is that the build quality could have been better.

Sharp wide-open; fantastic bokeh; responsive AF; physically a small and compact lens for the focal length

build could be more durable.
