Pentax Super-Multi-Coated Macro-Takumar 100mm f/4 - M42 Mount

The Super-Multi-Coated Macro-Takumar 100mm f/4 is a dedicated macro lens for the M42 screw mount, capable of 1:2 magnification without accessories. It is praised for its exceptional sharpness and flat field of focus, making it ideal for document copying as well as nature photography. The lens features the refined SMC coatings of the later Takumar era, significantly reducing flare and improving contrast when compared to earlier versions. When purchasing this model, it is vital to check the helicoid for smooth movement, as the long throw required for macro focusing can become heavy if the grease has dried. SDS inspects the aperture blades for snappy operation and checks for the presence of 'Takumar yellowing'—though this is less common in the 100mm f/4 than the 50mm f/1.4. The multi-coating should be inspected for any signs of fungal etching, which can be difficult to remove.
