Pre-Owned - Asahi Pentax Takumar 500mm f/4.5 (Non-SMC) M42 Mount

The "Takumar" 500mm f/4.5: The earliest version, simply labeled Takumar. It features single-layer or minimal anti-reflective coatings typical of the 1960s.

The Asahi Pentax Takumar 500mm f/4.5 (Non-SMC) is a vintage, manual-focus super-telephoto lens featuring an M42 screw mount, produced in the early 1970s before the introduction of Pentax's Super-Multi-Coated (SMC) technology.

Key Specifications

  • Focal Length: 500mm
  • Maximum Aperture: f/4.5
  • Aperture Range: f/4.5 to f/45
  • Optical Design: 4 elements in 4 groups
  • Mount Type: M42 screw mount
  • Minimum Focus Distance: 10 meters (approx. 33 feet)
  • Filter Size: 49mm rear-drop-in filters
  • Weight: Approx. 3,500 grams (7.7 lbs)

Performance & Characteristics

  • Coatings: Unlike the later Super-Multi-Coated (SMC) Takumar, this non-SMC variant features standard or single-layer coating, making it more prone to ghosting and flare when shooting toward bright light sources.
  • Image Quality: Sharp for a vintage long-focus design, though chromatic aberration (purple fringing) and lower contrast can appear in high-brightness situations.
  • Handling: Heavy and robustly built, requiring a sturdy tripod and patience with manual focusing. Because it uses an M42 screw mount, it adapts easily to modern mirrorless digital cameras using simple mechanical adapters.
