Description:
The PENTAX smc P Bellows 100mm F4.0 lens is designed to be used with the Auto Bellows, which can extend from 38-170mm. This lens is ideal for macro and copy photography. By moving the bellows to change the area of coverage, this lens can be extended from 38 to 170 mm in the normal position. Like all PENTAX lenses, this lens is treated with the acclaimed smc coating for maximum light transmission, sharp definition, and high contrast while minimizing flare and ghost imaging.
