Canon S-II (Seiki Kogaku)

The Canon S-II is a 35mm screw-mount rangefinder produced by Seiki Kogaku, the company that later became Canon. It was a postwar Japanese rangefinder built around the Leica thread mount, positioned as a domestic alternative to the Leica II/III pattern when new.

Sales data for the S-II is thin, but the two recorded UK auction hammer results sit at £300 and £800 — wholesale levels achieved in the saleroom rather than dealer asking prices. Today in 2026, condition, completeness of original markings and matching lens combinations heavily influence what a Seiki Kogaku S-II is worth, and clean, original examples sell for a clear premium over rough, reworked bodies.

Frequently asked questions

What is a Canon S-II (Seiki Kogaku) worth today?

Recorded UK auction hammer prices for the S-II range from around £300 to £800, with the price a given example sells for depending heavily on cosmetic condition, originality of engravings and whether a period lens is included.

How much does a Seiki Kogaku S-II sell for at auction?

With only two tracked sales, the value sits in a wide £300–£800 band at hammer; tidy, unmolested bodies tend toward the upper end while well-used examples sell for less.

Is the Canon S-II a good collector's camera?

It is of interest mainly to collectors of early Japanese rangefinders and Canon history, since it carries the Seiki Kogaku name from before the company adopted the Canon Camera Co. branding.
