Canon A35 Datelux
The A35 Datelux (also named the 'Nighter' in Japan; a reference to night-time baseball matches) is a 35mm rangefinder camera with date imprint, made by Canon in October 1977, several months before the A35F (the same camera without a date-imprint function) was sold in Europe and the Americas. It has a five-element 40mm f/2.8 lens, focusing down to 0.8 metre. The rangefinder is integrated into the viewfinder, which has frame-lines for parallax-error correction at close focus, and also shows the aperture scale with the meter needle, over- and under-exposure warnings, and a battery check. The camera is one of the last Canon made with manual rangefinder focusing (the A35F is the last), but their first with a built-in flash. The flash, with Guide No. 12 (metres, at ISO 100) is in the top housing, on the user's left (pushing the folding film-rewind crank toward the middle of the top plate). The flash is popped up and retracted manually, but exposure (with or without flash) is automatic. Exposure without flash is program AE controlled by a CdS meter between EV 9 and 17 at ISO 100. Flash exposure uses a system named CATS (Canon Auto Tuning System), computing the aperture to be used from the subject distance set on the RF and the film speed (just as manual flash is computed).
The date-imprint function can be switched off, with the switch seen on the front of the camera. The date is set on the lens barrel.
