Beck 135mm F/2.8 Lens Pentax K Mount

The Beck 135mm f/2.8 is a manual focus telephoto prime lens built for Pentax K mount cameras. As a third-party lens, it offers an accessible alternative to first-party telephoto optics while covering a popular focal length for portraits, compressed perspectives, and general telephoto work. The fast f/2.8 maximum aperture allows for effective subject isolation and solid low-light performance for a lens of this era. Focusing and aperture control are both fully manual, in keeping with the classic mechanical SLR lenses of its time. The Pentax K mount allows direct use on K-mount film SLR bodies, with broader compatibility available on later K-mount digital bodies through standard manual lens operation.
