Summary
The Takumar 50mm f/4 is a series of legendary manual-focus macro lenses for M42 screw-mount cameras, produced by Asahi Optical Co. in three main variants between 1964 and the early 1970s. All versions share the same 4-element/3-group optical design, optimized for flat-field reproduction and exceptional sharpness—hallmarks of classic macro lenses. This macro lens existed in both Macro-, Super- and Super-Multi-Coated variants. The Macro-Takumar was differently constructed compared to the other, later variants and went out to 1x magnification rather than the 0.5x of the later lenses. The optics are the same for all three variants.
