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.

Features:
– Focal length: 135mm
– Maximum aperture: f/2.8
– Lens mount: Pentax K mount
– Focusing: manual
– Aperture control: manual aperture ring

Victoria V. ★★★★★

Sharp as a tack wide open at f/2.8, and the bokeh has that lovely old-school swirl. Sure, the aperture blades are stuck, but I only shoot it wide open anyway so it's a non-issue for me.

Henry ★★★★★

Finally got this mounted on my K-5 and I'm honestly impressed with the image quality for the price. The all-metal construction feels like it'll last forever, just wish the aperture blades weren't stuck wide open.

Abigail ★★★★★

I knew going in that the aperture blades were stuck, but for the price that's exactly what I wanted it for. The 135mm focal length on my Pentax K mount gives me that classic manual telephoto look, and focusing by hand is smooth enough. It's a fun lens to tinker with, and the glass itself is surprisi
