The Type SK Primes are a remarkable reinvention of Canon rangefinder optics from the 1960s, wildly tuned and enhanced with new glass elements for modern filmmaking. These lenses maintain their vintage character with coatings that produce beautiful, low-contrast images and signature golden flares. Despite their roots in older optics, they deliver exceptional sharpness, even wide open, and exhibit surprisingly low chromatic aberration—an impressive feat for vintage-inspired high-speed lenses. Their distinctive painterly bokeh brings a richness and depth to images that is difficult to replicate with modern lens designs.
