This is a full-frame prime lens for Pentax K, covering 100 mm and a maximum aperture of f/2.8. Released in 2022, it weighs 348 g and is weather-sealed. That combination suits macro and portrait photography.

It is a versatile macro prime lens designed for Pentax K-mount full-frame and APS-C DSLR cameras.
