  1. Canon's own thread before 1951 was 39 mm at 24 threads per inch (1.058 mm pitch), against Leica's 26 tpi — close enough that the lenses interchange in practice, and the difference is why an early Serenar can feel tight on a Leica. The Serenar 50mm f/1.8 of late 1951 was the first Canon lens cut to the Leica pitch (Leica Copies Japan).
  2. Serenar became Canon Lens in December 1952, accessory lenses following in January 1953 (Leica Copies Japan). A lens engraved Serenar is therefore earlier than 1953; the same glass in a Canon-engraved barrel is not a different lens, and this catalog keeps both on one page as variants.

What reviewers say

History

Itō Hiroshi’s five-element 100mm, marketed in January 1953 at ¥22,000 (Leica Copies Japan has the Serenar version from October 1952), then in black-and-silver in April 1958 at 184 grams — a record for Canon and, Mechelhoff says, “very sharp” — and in a third barrel from March 1960. It replaced the three-element f/4 and became the lens the Canon rangefinder crowd calls their secret.

Dante Stella: a tiny long-focus lens that excels across the frame at every aperture, “sharp, and highly coveted,” the alternative to a heavy 85/2.
