You can see all the little, individual hairs on this flower. That's how sharp this lens is.

The above shots were taken at Longwood Gardens in Kennett Square, Pennsylvania. I've owned the Canon 100mm f2.8L for just over a month and I am totally smitten with it. I won't bore you with a long, technical rundown on bokeh and sharpness. For that, you can go to any number of photo review websites. This is not a review website, it's simply my thoughts on the equipment I use.
This lens is a great dual-purpose lens. I had a food photography shoot with it the first day I bought it and it really shined. Then I took it to Longwood Gardens for some macro shots and it showed why this is probably the best macro lens on the market today.
And it is RAZOR sharp. I mean, razor sharp! The above images are 72dpi and reduced down markedly, but you can actually see all the little hairs on the second photograph. When it's enlarged those hairs are incredibly detailed.
If you're not into macro, no worries. This is a brilliant portrait lens as well. Not as fast as the Canon 85mm 1.2L, but half the price and probably as sharp.
I highly recommend it!
