be attached to the lens to prevent draining the K1000's battery when it is not in use. The K1000 comes with its own simple, black camera strap out of the box. Conventional for the time, there is a film advance lever on the right and a rewind crank on the left on the top plate. There is a basic hot shoe for an electronic flash unit, and also a PC flash lead socket, of X type synchronisation. There are no flash dedication features. The viewfinder has a focusing screen with a microprism spot focusing aid. The Pentax K1000 SE substituted a split image rangefinder plus microprism collar focusing screen. Later (non-Asahi) SE models had top and bottom plates made from plastic, painted to look like metal. The K1000 SE is otherwise identical to the regular K1000, except that the SE's from the first two years of production in late 1977 to 1978 used a Black Diamond patterned leatherette (Pre 780XXX serial number) for approximately 2500 units and then a brown leather instead of black after that on the later early SE models. The K1000 has a Pentax K bayonet mount, a type introduced with the K Series. Originally it was usually sold with the budget SMC Pentax 50mm f/2 lens, and it accepts any other manual focus lens with the K mount. This includes the SMC Pentax, SMC Pentax-M and SMC Pentax-A types. In addition, almost all lenses with the Pentax K-AF and K-AF2 autofocus lens mounts (introduced 1987 and 1991, respectively) also work in manual focus mode. The exceptions are Pentax's newest SMC-Pentax FA J (1997) and SMC-Pentax DA (2004) types which lack an aperture control ring, and K mount lenses designed for APS-C cameras; these can be mounted but with restricted functionality. There are also adaptors to allow older screw mount lenses to be used on K mount cameras (with limitations). In all, there are vast numbers of Pentax and third party lenses that can be used with the K1000 and other K mount camera bodies. As a budget camera, the K1000 has fewer features than other mid-1970s SLRs. In particular it lacks a self timer, which can limit its appeal to family users. The sparse information in the viewfinder can make taking photos a little ponderous, as the camera might need to be removed from the eye to check settings, on top of which the meter is
