A few years ago Pentax revived the famous “star” series of optics, which were of very high quality. In the optical scheme of the star series includes lenses made of special varieties of high-quality glass, with a unique multi-layer coating, which provides increased light transmission and minimal light scattering inside the optical unit. The two lenses in today’s review belong to that series and are very reasonably priced.

The focal length for the APS-C format is 460 mm in 35 mm equivalent. This lens is also from the “star” series. Very compact, with a tough, dust- and waterproof body. Thanks to the internal focusing does not change the length when working.
The design of the focus ring allows you to switch to manual focus at any time. The SDM wave motor delivers ultra-fast and precise focusing. The optical properties are also remarkable: high sharpness and complete absence of chromatic aberration allow you to shoot with this lens for over-exposure.
Can you provide more details on the different telephoto lenses offered by Pentax? Are there any specific models that stand out in terms of image quality and performance? How do they compare to other telephoto lenses in the market? Would you recommend investing in a Pentax telephoto lens for wildlife or sports photography?
