This is a APS-C prime lens for Micro Four Thirds, covering 300 mm (450 mm equivalent on APS-C) and a maximum aperture of f/6.3. It weighs 260 g, and was released in 2014. That combination suits wildlife and sports photography.

It is a compact and lightweight mirror telephoto lens designed for APS-C mirrorless cameras. Utilizing a catadioptric (mirror) design, it achieves a 450 mm equivalent focal length in a portable form factor. The fixed f/6.3 aperture and manual focus operation make it suitable for daylight shooting conditions. The optical design includes an extra-low dispersion element and Ultra Multi-Coating (UMC) to minimize chromatic aberrations and enhance image clarity and contrast. Its compact size and lightweight build make it an excellent choice for photographers seeking a portable telephoto solution.
