Sigma 50mm f/2.8 EX DG Macro Autofocus Lens for Sigma SLR Camera USA
To maintain high optical performance from infinity to close-up 1:1 macro photos without accessories, the Sigma 50mm f/2.8 EX DG incorporates a "Floating Internal Focusing" (FIF) system. As a result, the lens also features a non-rotating front lens group which makes it easier to work with polarizing filters, and has a focus limiter to narrow down the broad focus range. And the improved minimum aperture of f/45 now provides improved depth of field.
This lens is designed as a high-quality primary macro lens, good for film or digital SLR cameras. The improved DG lens design corrects for various aberrations. This macro lens is specially coated to get the best color balance whilst cutting down on ghosting caused by reflections from the digital image sensor. The lens provides the utmost correction against lateral chromatic aberration which is a serious problem for digital SLR cameras.
- Close focus capability of 7.4"
- Super Multi Layer (SML) coating reduces ghosting caused by reflections from the surface of digital image sensors
- Screw-in hood also accepts a 72mm filter in the front of the lens hood

Comments about 50mm f/2.8 EX DG Macro Autofocus Lens for Sigma SLR Camera:
I purchased this lens to photograph a natural phenomenom knows as "frost flowers" and after using it to photograph similar sized objects in my home I realized I would need to be far too close to my intended subject in the field. However I did try it to copy some slides using my Sigma SD9 camera and found it to be very useful for this. I use the light head from my old dichoric head color enlarger and it works very nicely as a copy lens.
