This lens gets 5 stars from me on all counts - color, saturation, sharpness, contrast, clarity and bokeh. This one sentence should sum up my review.  Just for reference, I own the 135/2L and the 70-200f/4L IS lenses, both incredibly sharp, high quality  lenses and this ranks very much among the two in quality.  I also own the 85/1.8 and 50/1.4 and I would have to say that the 100/2.8 outranks the 85 and the 50 in IQ, color, saturation and contrast.  While the 85 and 50 are both excellent lenses, the 100mm just holds its ground.  I do have to add that the focus hunts quite often, which is more a characteristic of macro, and something that I am ok to put up with.  If slow focusing or hunting is not good enough for you, you may want to consider the other two macro lenses in the canon line up.

This lens has never failed me in any situation.  Even though I have had this for just 3 months, I have been tremendously pleased and very happy with the quality of the images.
This lens has brought out a whole new dimension in my photography and I couldn't be more pleased.  If I have a gripe, it is with Canon - they don't provide a hood for the macro lens, which you can very well debate if that is even necessary for for a macro.  The other gripe I have is that the macro ring lite flash is >$400!  Either ways, it has nothing to do with this lens itself, which is why the 5 stars.
