Overview
The Takumar 50mm f/1.4 (8-element) is the earlier version of Pentax's legendary fifty — often called the 'radioactive Takumar' due to its thorium-containing elements. Made before SMC coating, it has a different character: warmer colors, more flare, and a distinct vintage rendering that many photographers prefer to the later SMC version.
Verdict: For photographers who want character over clinical perfection. The 8-element Takumar has a look that's distinct and beautiful. Choose this for the warmth, choose SMC for sharpness.
Optical Character
