"Picked up lens just prior to Christmas. With mail in rebate offer and already applied lens sales price, the lens cost was just over $900. After having taken a few hundred photos over the holidays, I've got to say that this is one amazing lens.

This is such an incredibly sharp, hi quality lens. It has such incredible sharpness and great in low light situations. Incredible quality of photos, great for very close up insect shots. I loved this lens since the first time I used it! I would HIGHLY recommend this lens to anybody.

The lens is even better than I expected. Clarity is excellent. Depth of field is exactly as expected. My very first pictures were hand held and the IS worked very well. Others commented that the AF was loud - I found it to be barely audible.

A user friendly lens with astonishing sharpness. Combined with a good ring-flash it opens new micro worlds

Very impressed. I've wanted this lens for a long time. Grays' price was $500 cheaper than retail in Australia. Delivery from Hong Kong took less than a week. Grays give a 12 month replacement/refund warranty. Can't ask for better.

If you're looking for a macro lens, look no further. The canon 100mm macro F2.8L with IS offers 1:1 image replication. This enables you to snap postage stamp sized objects that will fill your entire frame.

Easy to use; Compact; Build quality

This is a superb lens not only for macro work but for general use. It gives you a good working distance with macro objects, and is equally suitable for more distant subjects. Quality holds at all f Stops. When used with my unforgiving Canon DFSr pictures are crystal clear and sharp.

Excellent lens good working distance from macro objects; suitable for all purpose use as well

none really; you may want to use manual focus in some situations for extreme close-ups

I liked the non-L version of this lens quite a bit, & got some wonderful photos with it. I was very hesitant to upgrade to the L IS version because I had read that there wasn't much to be gained by upgrading. I finally bit the bullet, sold my other lens, & ordered this one.

This lens has blown me away. It is my first IS lens from Canon. I own a 85 1.2L and it is slow to focus and forget about hand hold as it has no IS. This 100 2.8L macro is super sharp, fast auto focus and accurate as well.

Consistent Output; Durable; Easily Interchangeable; Fast; Fast / accurate auto-focus; Hand hold with ease; Lightweight; Manual focus feels good; Manual focus override; Nice Bokeh; Rugged; Strong Construction; Very Sharp

NONE

This lense has exceeded my expectations. The macro is great, but I was surprised at how awesome it works as a portrait lens as well. Extremely sharp but beautiful bokeh for macro and portraits.
