CANON EOS 850 QD (Quartz Date) film-based 135mm (36 x 24mm) format AF-SLR camera,
Approx. Product Cycle: 1988 ~ 1989
Type: 35mm autofocus, single-lens reflex camera with electronically-controlled automatic exposure, focal plane shutter, built-in motor drive but without built-in flash design as in the case of the Canon EOS-750. The camera was quite short lived, it lasted only a year in the market (shorter than the EOS 750 which lasted a year more).
Canon Autofocus EF Lens Resources
* The EOS 850 (QD), sister model of the EOS 750, does not have a TTL built-in flash, but by using the Speedlite 160E, it is capable of fully auto shooting just like the EOS 750.
* Auto date models are provided with five imprint date items (including OFF).
* Similarly with the EOS-750, a pre-wind film advance mode in which all of the film is wound forward when the camera is loaded and then rewound back into the cassette one frame at a time as the photos are taken. Mid roll rewind is not possible with this model. The film advance speed is approx. 1.5 fps. Replaced by EOS700 in 1990.
Viewfinder Type: Fixed pentaprism SLR. Gives 92% vertical and horizontal coverage of actual picture area. and 0.8X magnification at infinity with a 50mm f/1.8 lens.

1. AF in-focus symbol: Lights up when AF is possible. Blinks at 8Hz when AF is not possible. In Depth-of-Field AE Mode, blinks at first and second in-focus. Blinks at 4Hz when the subject is out of the focus zone.
2. Exposure symbol: Lights up for correct exposure and flash charge completion. Blinks at 2Hz for camera-shake warning. Blinks 8Hz for out-of-coupling range warning. Off when flash is charging. See EOS 750 section for more
Mirror: Quick-return half-mirror.
Focusing Screen: Fixed, full-screen New Laser Matte screen with AF frame

Film Wind: Automatic using a built-in miniature motor. Continuous mode only; Single exposure mode with Depth-of-Field AE mode. Confirmation by frame counter.
Metering System: TTL full aperture metering using SPC 6-zones Evaluative metering only.
Metering Range: EV 0 to +20 (50mm f/1.4 lens @ ISO 100) (EV 3-20 in high temperature and humidity)
Exposure Modes: (1) Intelligent Program AE. (2) depth-of-fleld AE, (3) TTL program flash AE (with built-in flash or the Speedlite 160E), automatic fill-in flash and automatic flash at low-light level, (4) A-TTL program flash AE (with Speedlite 420EZ and 300EZ)
Film Speed: ISO 25-3200 is automatically set by I step according to DX code, For non DX-coded film, set to ISO 25.
AF Control System: TTL-SIR (TTL secondary imaged registration) phase-detection type using BASIS (base-stored image sensor), AF in-focus symbol lights in viewfinder and short beeper tone emits. Beeper tone cannot be turned off. When AF is impossible, in-focus symbol blinks at 8Hz
Focus Mode: 1) ONE SHOT mode: AF operation ends and focus is locked once ranging is completed. Shutter can be released upon completion of ranging; 2. Manual: By rotating the manual focusing ring after focus mode switch is set to "M".
AF Working Range: EV 1-18 at ISO 100.
AF Auxiliary Light: The dedicated flash operates with EOS 850. Both 750 & 850 operate when flash condition detected.
Camera-shake Warning: When automatically-set shutter speed falls 0 to 0.5 steps below focal length of the lens in use, 'P' blinks at 21-12. No camera-shake warning when the built-in flash or dedicated flash is used.
Power Source: One, six-Volt lithium battery pack (2xCR5) supplies power to body and built-in flash (only apply to EOS 750/750QD model)
Battery Checker: Main dial switch at BC; By totaling the selector dial to the battery check position, OK: at 8Hz, have a new battery handy, at 2Hz, no tone: battery exhausted.
