Pentax SMC 100mm F/4 Macro M42-Mount Lens

This Pentax SMC 100mm f/4 Macro is a gem from the Takumar series—designed for the classic M42 screw mount. It’s a beautifully sharp macro lens with true 1:2 reproduction and razor-sharp rendering that holds up even by today’s standards. With a long focus throw and lovely handling, it’s an ideal choice for macro photography of flowers, textures, small objects, and product work. Adapted to digital mirrorless, it becomes a punchy short telephoto for portraits with crisp detail and gentle bokeh.

Pentax's legendary Super-Multi-Coating (SMC) ensures strong flare resistance and rich contrast, making it an excellent tool even in challenging lighting situations. Whether you're mounting it on a Spotmatic or adapting it for use on your modern mirrorless setup, this lens delivers gorgeous analog character.

Condition: Excellent

This lens is in excellent condition with only minimal signs of use. The glass is clean and clear with no haze, fungus, or scratches. Focus and aperture rings turn smoothly, and the aperture blades are clean and snappy. Threads are in great shape and mount securely. A top-tier example of this legendary vintage macro lens.
