Product Description

Amazon.com Product Description

Sigma launched its first standard 50mm macro lens in 1990, and followed it up with an improved model in 1998. The advent of digital SLR cameras, however, required updated optical technology and a better imaging performance. Enter the latest incarnation of the 50mm macro lens, with an improved design that corrects for various aberrations. Designed exclusively for Canon SLR cameras, this macro lens is specially coated to get the best possible color balance while cutting down on ghosting caused by reflections from the digital image sensor. The lens also includes a floating focusing system, which allows you to precisely photograph objects throughout the entire focusing range. Most importantly, this standard macro lens makes it possible to enjoy better communication with your subject. When viewing through the camera's finder, you'll be able to move the subject and make precise adjustments. For example, the lens offers a close working distance of 7.4 inches, making it extremely convenient to take close-up pictures of a fossil or other inanimate objects.

Other details include a minimum aperture of f/45 that provides a greater depth of field than most lenses, a screw-in lens hood that makes it easy to attach circular polarizing filters, and a 46.8-degree angle of view. All Sigma lenses carry a one-year warranty.

5.0 out of 5 stars Excellent Lens, July 9, 2006

By	Airlee Owens "Airlee" (Bandon, Oregon) - See all my reviews (REAL NAME)

I recently purchased the Nikon D200 camera. I had several nice zoom lenses but I did not have anything which would take macro close-up photos. I did some research and found good reviews for this lens. So I got it.

The lens is an excellent lens for close-up photos. I am not a professional photographer but I try really hard to get good sharp photos. This lens will do the job.

Since it is also also a 50mm lens I have used it as a normal lens. The only problem with that is that over the years many of us have been spoiled with zoom lenses. With a zoom lens you can stand in one spot and zoom the lens in or out to get closer or father from your subject. With just the 50mm capability of this lens you have to physically move in or out to get a closer shot or a wider shot. This is not necessarily a criticism, just a comment about how we have been spoiled by zoom lenses.

I do not believe you will be disappointed with this lens. The price is great for the quality.

5.0 out of 5 stars Great lens for the price., December 29, 2007

By	B.E. "Deal Seeker" (NJ, USA) - See all my reviews

For the price I am happy with this macro lens. I purchased it for a Nikon D40 DSLR. It will not auto focus with this camera, as a AF-S lens is needed for that; but those are in the range of $700+; so this lens is fine with manual focus, and for $550 or so less than one that will auto focus with my camera. I am happy with the photo quality that it produces.

4.0 out of 5 stars Sigma 50mm EX DG MAcro lens, April 14, 2007

By	T. Livengood "Aplseed" (Central Iowa) - See all my reviews (REAL NAME)

This was my first non canon lens,I was wanting a macro lens that also would be a good low light lens to use in the home to take photos of my pets at play.After reading many reviews I was concerned about the Auto focus being too slow for my needs,but I just couldn't spring for a Canon 60mm Macro at this time.
My lens came today,and I have to say I am fairly pleased.It does not hunt like my 28-135mm always has,and the AF is fairly fast,even in the low light of my living room with no interior lights on and only one window curtain open during daylight.The limitor switch does speed it up noticable as well. The colors is what has impressed me so far,The browns of my chocolate lab's coat were true,and had nice highlights I had never been able to get before.The lens fgocuses very close to an object as well,and I am looking forward to comparing my macro shots to the ones I got with my 28-135 with a macro filter applied.
There have been complaints that the hood doesnt fit the lens cap,but I think a 72mm lens cap would work well on the hood itself and would solve this problem for those who keep the hood on the lens.
