Auto Sears Tomioka 135mm f/2.8 Telephoto Lens – Pentax K Mount

The Auto Sears 135mm f/2.8 isn’t just a budget telephoto—it’s a hidden gem, made by one of Japan’s most respected optical manufacturers: Tomioka Optical Co., the same legendary lensmaker behind early Yashinon lenses and the ultra-coveted Tomioka 55mm f/1.2. Throughout the 1970s and early 1980s, Tomioka produced high-quality optics for a number of rebranded lenses sold by companies like Sears, Ricoh, and Chinon. While these Sears-branded lenses flew under the radar for decades, they’ve become increasingly sought after by vintage glass enthusiasts who recognize their pedigree.

This 135mm f/2.8 is a classic short telephoto lens, ideal for portraits, nature photography, and creative compression effects. The large maximum aperture allows for beautiful background blur and solid low-light performance, while the manual focus throw is long, smooth, and precise—exactly what you’d expect from a Tomioka-made lens.
