Summary
The Super-Takumar, Super-Multi-Coated (S-M-C), and SMC Takumar 50mm f/1.4 are a celebrated series of fast M42 screw-mount prime lenses produced by Asahi Optical Co. from 1964 to 1975. All later versions share a refined 7-element/6-group optical design, a bright f/1.4 aperture ideal for low-light and portrait photography, and a minimum focus distance of 0.45m. They feature a 49mm filter thread, weigh around 230–252g, and measure approximately 61.5 × 38.5mm. The 8-blade diaphragm (6 blades on early Super-Takumar) produces smooth, creamy bokeh, while the Super-Multi-Coated and SMC versions add improved flare resistance and open-aperture metering support on compatible Spotmatic bodies. These lenses are prized for their sharpness, contrast, and vintage rendering, and remain a favorite for adapting to digital mirrorless systems. Some 7-element versions contain thorium glass, which may yellow over time but can be cleared with UV exposure. They can be adapted to modern DSLRs and mirrorless bodies.
