Pentax is back! While users patiently waited through 2019 for any news, work was ongoing behind the scenes to perfect works on a new K-mount lens. Some days ago, Pentax’s parent brand, Ricoh, announced the launch of a new K-mount lens — the first since the last DSLR K-1 Mark II was launched in 2018.

The new Pentax 70-210mm f/4 ED SDM WR is a lightweight versatile telephoto zoom lens that was developed for Pentax DSLR cameras. This new Pentax 70-210mm f/4 ED SDM WR is a compact high-performance telephoto zoom lens with a weather-resistant construction that makes suitable for various outdoor applications.

In addition to its high portability, this new high-performance zoom K-Mount lens covers a 35mm full-frame image circle. It offers users the ability to take high-quality shots of various subjects, be it landscapes, sports events, portraits or close-ups. 

Its high-grade, multi-layer HD Coating ensures edge-to-edge sharpness and cuts down on flaring and ghosting in backlit situations to the barest minimum. Due to its large focusing distance and impressive magnification, the Pentax 70-210mm f/4 ED SDM WR offers much better photographic coverage than that of previous models.

Ricoh says that the new 70-210mm f/4 K-Mount lens offers a more compact, lightweight option for use in outdoor photography, be it sports, wildlife, and even scenic shots.

In September last year, the company had teased a new flagship crop sensor camera still under development, that was supposed to debut sometime in 2020. There’s no information about its name, pricing or more precise launch date at the moment.

Its focal length range further extends to the equivalent of 107mm to 322mm (in the 35mm format) when mounted on an APS-C-format camera.

The new lens HD Pentax-D FA 70-210mm f/4 ED SDM WR (its full name) touts an optical construction comprising 20 elements arranged in 14 groups. Among these elements are three extra-low dispersion (ED) glass elements and “two anomalous dispersion glass elements.” These elements ensure that it provides or high-contrast, high-res photographs with edge-to-edge sharpness and compensates for distortion and chromatic/coma aberrations.

This new K-Mount lens boasts a short minimum focusing distance of 0.95m and a max magnification of 0.32x. Additionally, the lens barrel design makes it extension-free during AF operation to ensure that the length of the lens doesn’t change while focusing.
