Canon IIS (1954–1955)
A 35mm rangefinder camera with a back-loading design, produced by Canon for a short period in the mid-1950s.
Overview
The Canon IIS is a 35mm rangefinder camera introduced in early 1954 and produced through 1955. It was part of Canon's early PX series of rangefinders, sharing design traits with models like the IIF, IIIs, and IVs. Unlike later swing-back designs, the IIS uses a back-loading mechanism, which requires removing the baseplate to insert film. It was marketed alongside the Canon IIF and succeeded the Canon IVSB. Despite its brief production run, the IIS gained a reputation for solid build and functional performance, with owners noting a clear, contrasty rangefinder and reliable shutter operation.
