  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. camera-wiki dates the first version August 1959 and the second undated; the Canon Camera Museum has November 1957 and August 1959. The museum's dates are used.

What reviewers say

History

Itō Hiroshi’s six-element Planar — a Biotar type in Mechelhoff’s description — marketed in November 1957 at ¥25,000, revised in August 1959 with a dual-unit distance scale, and made until about 1967. It sat below the f/1.2 in the range and above it in reputation: Mechelhoff calls it “a really great everyday lens,” very sharp and contrasty with excellent bokeh.

BastianK, who tested both, found this f/1.4 outperforms the f/1.2 — less soft wide open, sharper stopped down, better value — and calls it “a good and also sensible choice.” Andrew Morang’s copy on a IIIc showed “superb craftsmanship, typical 1960s Japanese optical excellence” for about $110. The one warning is the same for every fast Canon: the big front element can focus the sun onto a cloth shutter. Original US price around $210 in 1963 (Morang).
