The Yashica Yashinon-DS belongs to Yashica's family of standard M42-era prime lenses, a lineage that the reviews describe across several closely related variants. The evidence covers the DS-M 50mm f/1.7, introduced in the mid-1970s as a multicoated successor to the earlier DS and DX series, and the earlier chrome-barreled Yashinon-DX 50mm f/1.4. According to the reviews, the DS-M was 'designed as a multicoated successor to the earlier DS and DX series' and, though 'often overlooked in favor of Takumars and Zeiss Planars,' is regarded as 'a hidden gem for manual-focus enthusiasts.' The earlier DX line is described as jewelry-like in construction, prized as much for history and looks as for pure performance. One reviewer noted the DX f/1.4's strong flare resistance was 'most likely a result of the inclusion of thorium elements,' hinting at the radioactive-element construction sometimes found in fast vintage glass of this period, though this is only asserted for the DX f/1.4. No established community nickname is evidenced for the DS line. People love these lenses for their combination of solid-to-exquisite build quality, natural rendering, and remarkable value, with the DS-M in particular being a strong, affordable performer.
Verdict: The Yashica Yashinon-DS family is for the manual-focus enthusiast who wants classic double-Gauss rendering — neutral, slightly cool color and strong contrast — at exceptional value. The multicoated DS-M 50mm f/1.7 rewards those who stop down to f/2.8, delivering sharpness and pleasing bokeh that hold their own against better-known Takumars and Planars, while tolerating some softness and fringing wide open. The earlier chrome DX variants add jewelry-grade build and collectible appeal. Choose these lenses for their honest rendering and craftsmanship rather than clinical wide-open perfection.
Neutral to slightly cool color rendition.
Sharp from f/2.8 onward, with softness and fringing wide open.
Decent flare resistance for its age.
Excellent contrast when stopped down, notably better than many contemporaries.
