Sony 50mm f/2.8 Macro A-Mount Autofocus Lens [55]

Manufacturer's Description: 

Photographers who are attracted to details need a lens that lets them 
get in close when necessary, filling the frame with their diminutive but 
fascinating subjects. A lens like the SAL50M28, with a minimum focusing 
distance of just 20 centimeters and up to 1:1 magnification, can open 
up a world of creative possibilities. But there’s no need to change 
lenses when you want to go back to shooting at normal distances. 
The SAL50M28 offers outstanding optical performance for general 
photography as well, and its 50mm focal length is a very versatile choice 
for 35mm full frame format cameras. On APS-C format cameras you get a 
little more reach, which can be advantageous for some normal subjects 
as well as macro shooting.
