The legendary FA* 85mm f/1.4 lens was created by PENTAX approximately 20 years ago, receiving high acclaim worldwide. Now its digital successor is here. The smc PENTAX DA* 55mm is more than equal to its analogue predecessor: tremendous light gathering capabilities, circular diphragm for outstanding bokeh and a fine progressive rate of sharpness depth. Additionly, the lens features a newly developed PENTAX lens coating that further reduces light loss and reflections. For the professional portrait photographer this lens is undoubtedly the finest on the market. It is developed exclusively for the use with SDM compatible cameras.
