I have had this lens for several months now. I work as a semi pro freelance photographer and use generally L' lenses. I have to say that I have been pleasantly surprised with this macro lens and use it with extension tubes. A brilliant lens with great results

this is a great lense with very clear optics.

good optics

a bit heavy

I use this with my 40D (cropped sensor) and have had excellent results. Sharpness and colour are exceptional. The macro function can be difficult and takes time to learn how to use effectively due to the shallow depth of field and exaggerated camera movement.

I considered this for a long time as it's not cheap. I nearly settled for the 60mm macro lens but online reviews suggested that this was a bit more flexible. I've used it hand held for macro work in my garden so far and am really pleased with the results.

Consistent Output; Easily Interchangeable; Quick Focus; Sharp Focus; Strong Construction

I AM USING THIS MACRO LENS ON A SONY NEX 7 CAMERA WITH A METABONES ADAPTER FOR MACRO AND PORTRAIT PHOTOGRAPHY. I FIND THE LENS TO BE STURDY AND WELL BUILT. BOTH PORTRAIT AND MACRO PHOTOS CAME OUT IN VERY SHARP FOCUS. THE SHALLOW DEPTH OF FIELD FOR MACRO CAN GET VERY SENSITIVE.

Consistent Output; Durable; Nice Bokeh; Rugged; Strong Construction

Slow Focus

I love this lens. Since we got it, it is almost always on my camera, It takes amazing portrait shots and sharp macro shots. Amazing. I strongly suggest that this lens be in everybody's lens kit. I would only replace it with the L series lens if I have oodles of money to spare.

"""So You Want To Major In Macro"" Then this is the Lens for you. I am absolutely in LOVE with this Lens! Crisp, Clear and to the POINT...This lens really promotes the beauty of Macro and affords me the opportunity to truly Explore my Passion for Macro Photography!!! Well Worth The Investment!!"

I chose this lens over several more expensive models based on test reports, user reviews and, above all, price. While it may not have the build quality and weather sealing of those more expensive models, it still feels quite well built.

A big cons is the lack of IS but not for macro work, for portraits. Only for macro is just perfect.

excellent IQ

some focus hunting in low light

This is a great lens for a great value. I added this lens to my newly forming collection and LOVE it. Extremely crisp, clear and vibrant pictures.
