Pentax (Takumar) Pentax Takumar 55mm f2 Heritage

Overview

The Auto-Takumar, Super-Takumar, and SMC Takumar 55mm f/2 form a family of classic M42-mount standard primes produced by Asahi Optical Co. from the late 1950s through the mid-1970s. According to the reviews, they were often overshadowed by their faster f/1.8 and f/1.4 siblings, yet remained beloved for their compact size, smooth rendering, and vintage character. All versions share a 6-element/5-group optical formula, with coatings and mechanics evolving over time: the Auto-Takumar (1958-1959) used a semi-automatic diaphragm with a 10-blade aperture, the Super-Takumar (1962-1974) moved to a fully automatic diaphragm with 6 blades, and the SMC Takumar (1972-1975) added Super-Multi-Coating for improved flare resistance and contrast. They were typically bundled with Asahi Spotmatic bodies (and cameras like the Pentax Asahi SV) and remain fully compatible with modern digital cameras via M42 adapters. No specific nicknames are established for this lens in the reviews; while jargon exists for other Takumars, none is documented here for the 55mm f/2. People love it for its all-metal build, buttery long-throw focus, and a gentle, classic rendering that flatters portraits and everyday scenes.

Verdict: The Pentax Takumar 55mm f/2 is a compact, beautifully built M42 standard prime for photographers who value tactile handling and gentle, classic rendering over raw speed. Though overshadowed by its faster f/1.8 and f/1.4 siblings, it rewards users with crisp center sharpness, smooth bokeh, and a subtle vintage glow wide open, all at a very affordable price. It's an ideal choice for film shooters learning deliberate photography and for mirrorless users seeking a characterful, distinctive portrait or video lens.

Optical Character

Bokeh

Smooth, rounded, and unobtrusive out-of-focus rendering, pleasant and creamy in a classic, restrained way with no swirl or bubble effects.

Sharpness wide open

Crisp center sharpness wide open, becoming impressively crisp when stopped down; corner details not documented.

Flare resistance

Earlier single-coated versions can lose contrast facing the sun; the SMC version added Super-Multi-Coating for improved flare resistance.

Contrast

Gentle/pleasant contrast wide open; clean and precise stopped down, with the SMC version improving contrast over earlier versions.

Community Insights

What people love

Compact, all-metal, beautifully machined build with engraved distance and depth-of-field scales
Long-throw, buttery-smooth focus rings that preserve their action even on aged copies
Gentle, classic rendering with a subtle vintage glow wide open that flatters portraits
Crisp center sharpness and pleasant contrast, becoming precise and clean stopped down
Smooth, rounded bokeh and a natural field of view with subtle compression
Excellent value on the used market and full compatibility with modern digital cameras via M42 adapters

What people dislike

Struggles with bright light and can lose contrast when facing the sun, especially earlier single-coated versions
M42 screw mount can unscrew when closing the aperture if the mount is not properly locked
Earlier Super-Takumar copies may yellow slightly over time
Slower f/2 aperture gives less subject separation than the f/1.8 and f/1.4 siblings

Pro Tips

Avoid pointing the lens directly at the sun to preserve contrast; use a lens hood in bright conditions
Shoot wide open for that subtle vintage glow on portraits, and stop down to f/2.8 or beyond for crisp landscape and documentary work
Always secure the M42 mount firmly before shooting so it doesn't unscrew when closing the aperture
For yellowed earlier copies, prolonged UV light exposure can reduce the discoloration
Pair with ISO 100-400 film such as Kodak Portra or Ilford HP5+ for the best film results
