This is my first macro lens. The choice was between the Canon 60mm 2.8 macro or this one. After much research and a sale price drop of $80 from OneCall, I chose this one. The sale price put the new price from OneCall in an acceptable range with an used one. I am glad I chose this one.

Consistent Output; Durable; Easily Interchangeable

The Canon EF 100mm f/2.8 USM Macro Lens is a very good choice for macro photography of butterflies, insects or flowers. It offers excellent optical performance and middle-of-the-road working distance, size and weight.

1; Fast Focusing - Utilizing USM (Ultrasonic Motor), the Canon 100 Macro internally focuses very fast, quietly and very accurately, 2; Non-Extending or Rotating - When focusing at 1x subject distances, the lens does not extend, and the front element does not rotate, 3.

1; Build quality - this USM Macro lens has a reasonable build quality although it's not quite as solid as the L-Series lenses, 2; Image Stabilization - this lens does not feature the image stabilization present with the significantly more expensive Canon EF 100mm f/2.8 L IS USM Macro Lens

I upgraded to IS version of this lens, and its so easier to take pics now, big difference.. Bout this one for 479 one year ego..

Its a nice lens; pretty sharp.

had to use manual focus to get sharp images

I'm in a Master's course and this lens is so good I've been able to put off buying the really high priced version while.Does great in lower lighting which was my main concern.

Easy To Set Up; Easy To Use

I am considering buying this lens and you can buy this lens all day long from other well known retailers for $599.99. I was hoping these people here would be at least the same as these other retailers maybe even cheaper but as we can see they are alot higher not only on this lens but I've noticed...

Yes, I would recommend this to a friend

Fast / accurate auto-focus

If you want to jump into macro photography making compromise in image quality, this lens is the perfect choice, here is why: - Very good image quality, L rated. - Nice build quality. - A joy to use the very large focusing ring. - Pretty good for portrait too.

A bargain; sharp image; build quality; large and nice focusing ring

maybe a bit heavy

The Canon EF 100mm f/2.8 USM Macro is one of two new 100mm macro lenses in Canon's range, the other being the more expensive L-series optic, the CanonEF 100mm f/2.8L Macro IS USM, which has the advantage of a new Hybrid IS system.

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
