Product Description
The Sigma Corporation is pleased to announce the launch of the new Macro 70mm F2.8 EX DG lens . This medium telephoto macro lens is ideal for both digital SLR cameras and 35mm film SLR cameras. The 70mm focal length gives an equivalent field of view as our popular 105mm macro lens when used on digital SLR cameras with an APS-C size image sensor. The design of this lens makes it suitable for taking pictures in all situations from infinity to 1:1 macro, both with natural light conditions or flash. A Special Low Dispersion (SLD) lens and two high refractive index SLD lenses provide excellent correction for all types of aberrations and produce an exceptional level of optical performance. Sigma?s super multi-layer lens coating reduces flare and ghosting, and helps create a natural color balance. The floating focus system provides extremely high optical performance from infinity to 1:1 Macro. A Focus Limiter Switch is incorporated on the lens, improving the speed and accuracy of autofocus by limiting the focus range. A screw-in lens hood is included for convenient use of circular polarizing filters.

I probably just echo Thomas Summer's comments, but this is a great lens at any price, and in comparison to the cost of the Canon equivalent it is a super value purchase. Even though lens reviews and tests are usually based on just one example, the review in Popular Photography convinced me, and I am glad I made the choice. My only complaint is I don't really like the dull, "sandblast" finish, but I can live with the cosmetics for the build and lens quality. One feature I really like is that I can use it both on my digital and full frame film camera bodies.

I tried the Canon 60 macro for a month and it was okay but ended up buying the 70 mm Sigma macro. The extra reach and, IMO, much sturdier build quality decided my purchase. Three other lenses I own are Canon L lenses, so I am critical about lens quality. The Sigma 70 macro is as sharp as a tack. A superb lens.

i started using this lens only in close up pictures then i found that i can focus to infinity with it. i use it as an all around lens now. it helps of course that it is a 2.8 lens. the only things i can't shoot with it is for detail in far off picture. still need the ole 70-300 or 50-500 lenses for that.
