This Lens is awesome and holds up to the hype. It shows a 1 to 1 Macro ratio and provides great Bokeh/background blur for up close and Portrait photos. The IS makes hand holding a breeze...I do almost all my shooting hand-held and definitely need the IS, and with this being an L lens as identified by the red ring, it becomes a must have for your camera bag and you will not regret it. I’ve added 2 photos taken with this lens below...

I love this lens!!!! Tack sharp and IS works great! This lens can be used for more than just macro photography. I've used it for everything from landscapes to portraits. Autofocus may be a bit slower than some of the non-macro lenses with a similar focal length but using the focus limiter switch greatly helps with focus speed. If you are looking for a macro lens and shoot Canon get one.

I love this lens! Very sharp crystal clear images that when blown up gives excellent detail without losing clarity. I use this lens most of all because I can get nice macro shots as well as beautiful portrait shots. Worth every penny!

I wanted to add a macro lens to my kit and decided on the Canon 100mm f/2.8 L lens. What an outstanding lens it is! Incredibly sharp and crisp. As you will read in practically every review you see, it is an excellent choice for macro.

I've had other macro lenses in the past but nothing like this!!! The images are pristine! I can't say enough about this lens. If you want a macro....this is the BEST!
