SMC Pentax FA J 28-80mm F3.5-5.6 AL, serial number 6594667, in tested working order.
The lens is in excellent condition. The glass is clean and clear, the focus and zoom rings turn smoothly, and the aperture blades are snappy. Front and rear lens caps are included.
This lens does not have an aperture ring, so it can only be used on camera bodies which include off-lens aperture control. Some Pentax film camera bodies can use this lens in program ("P") or shutter-priority ("TV") modes, while other film camera bodies such as the Pentax *ist can use it in all metering modes. The lens can be used in all metering modes on all Pentax digital SLR cameras.
