Sigma 50mm f28 EX DG Macro Lens

Product Description

Style: Nikon SLR Cameras 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 Nikon 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/32 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.

This review is from: Sigma 50mm f/2.8 EX DG Macro Lens for Canon SLR Cameras (Electronics)
I have a Canon EOS 30D that I've owned for about 2 years. I've been wanting a macro lens for a while, but have had a hard time justifying the cost... especially since I originally had my eye on Canon's 100mm macro. Then someone suggested this Sigma lens to me, and I noticed that all the reviews were incredible. I was nervous about going with a 3rd party lens, but the price was right and the reviews gave me confidence. And also, I preferred the 50mm focal point vs Canon's 100mm (makes it a more versatile lens, in my opinion).

So then this christmas my dad gave me money to buy the lens, and I've only had it a few days now but I am already in love! This lens is wonderful-- the look and feel are good, and it takes GORGEOUS photos both close-up and otherwise. I've simply been using manual focus for close-up shots, but I've been very surprised at how fast the AF is (with the limitor switch on). It really is almost instantaneous, which is awesome. I think even faster than my other lenses (Canon 50mm f/1,8, Canon 17-85mm).

I borrowed my friend's 100mm macro lens last year, and honestly I don't see a significant quality difference between the two (though I am also not a pro, so may not have a critical enough eye for that sort of thing). Basically, I am VERY happy with this lens, right out of the box. The photos are gorgeous, razor sharp at the focus points, beautiful bokeh elsewhere, colors are very pretty, etc etc etc. This is a great alternative to more expensive macros. I actually wonder if this will replace my "nifty fifty" as my favorite lens... we'll see. ; ) Get More Full Detail>>
