Manufacturer description #1
The three leaf shutter lenses (A55mm f/2.8N/L, A80mm f/2.8N/L and A150 f/3.8N/L), in Seiko shutters, with speeds of 1/30, 1/60, 1/125, 1/250 and 1/500 sec., are of superb optical quality and are made in the focal lengths which are generally used in synchro-flash photography.
