Sigma Lens Autofocus Macro 50 MM F2.8 EX for Minolta / Sony SLR Camera
- Reviews (0)
To maintain high optical performance from infinity to close-up 1:1 (life-size) macro photos without accessories, the Sigma 50mm f/2.8 EX incorporates a floating element focusing system. Designed as a quick-focusing macro lens, the AF speed of 50mm, f/2.8 EX Macro is 1.4 times faster than previous 50mm f/2.8 macros. It features a non-rotating front lens group which makes it easier to work with polarizing filters and has a focus limiter (eg. Full Range infinity – 9.8 /25cm 9.1 – 7.4 /23 – 19cm). The Sigma 50mm f/2.8 EX Macro lens also features the new deluxe EX external finish. A handy screw-type metal sunshade makes it easier to rotate a polarizing filter.
Condition is as new, in original packaging, little or no signs of use.
