The K1000 is an almost-all metal, mechanically (springs, gears, levers) controlled, manual-focus SLR with manual-exposure control. It is completely operable without batteries. Batteries are only required (one A76 or S76, or LR44 or SR44) for the light metering information system. This consists of a centre-the-needle exposure control system using a galvanometer needle pointer moving between vertically arranged +/- over/underexposure markers at the right side of the viewfinder to indicate the readings of the built-in full-scene averaging, cadmium sulfide (CdS)battery light meter versus the actual camera settings. The meter does not have a true on/off switch and the lens cap must be attached to the lens to prevent draining the K1000\’s battery when it is not in use. The K1000 uses a horizontal travel, rubberized silk cloth focal plane shutter with a speed range of 1/1000 second to 1 second, along with Bulb and a flash X-sync of 1/60 second. It is 91.4 millimetres tall, 143 mm wide, and 48 mm deep, and weighs 620 grams. The body is finished in black leather with chrome trim only, although early production Pentax K1000 SE bodies have brown leather with chrome trim.
