Canon S-II (Seiki Kogaku)

{"overview":"The Canon S-II is a 35mm screw-mount rangefinder produced by Seiki Kogaku, the company that later became Canon. 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.","buying_guide":"Inspect the rangefinder for clarity and accurate vertical\/horizontal alignment, check the cloth shutter curtains for pinholes and capping at high speeds, and confirm the slow-speed escapement runs cleanly. Originality is critical on early Seiki Kogaku bodies: look closely at engravings and top-plate markings, since refinished or re-engraved examples are known and sharply reduce value.
