I have used this lens for over 2 years now, with both crop frame and full frame DSLR's (T3i/5d,6d) - it is one of the best pieces of Canon glass that I own, if not the best.
If you do a lot of outdoor macro/closeup work, as I do, I would heartily recommend that you have one of these mounted as your first choice.
On the rare occasions where I've done portrait work, it excels at that, too.
The colors are sharp, and the bokeh is amazing!!!!!

This is such a versatile lens. It is sharp to the edges and very bright. I am very happy I purchased it.

My favorite lens!!!
I had wanted to buy a dedicated macro lens, and after debating this versus the non-L version I make the leap and purchased this lens. Within a month, this has become my absolute favorite lens! If I could only keep one lens this would be it. In addition to its macro capabilities, which are great (especially if you add a Canon 25mm extender), the optics and bokeh on this lens are superb!!! The level of detail it captures, even at f/2.8, is simply amazing. Portraits, hummingbirds, dragonflies, you name it. This lens has the clarity and speed to do so much more than just macro. If you are thinking about it, just get it. You won't regret it!

Overall this is an excellent lens. It shows great details and expresses full potential as a macro L lens. Job well done, Canon! Although it's slightly pricey, it's worth every penny. It occasionally focuses on an undesired area of the object on auto mode, but by switching to manual mode will fix the problem. It's also good for portrait shooting as well.
