Pentax's entry-level M-series SLR — the MV, aperture-priority auto, K mount, 1979.
The Pentax MV is a 35mm film SLR that Asahi Optical launched in 1979 as a simplified, budget member of the compact M-series that began with the MX and ME. It sat below the ME in the range, aimed at first-time SLR buyers who wanted aperture-priority automation without the cost of the fuller-featured bodies. It uses the Pentax K bayonet mount and was sold under the Pentax name across the UK and Europe.
It is a 35mm single-lens-reflex camera taking Pentax K-mount lenses, built around aperture-priority automatic exposure. The photographer sets the aperture on the lens and the electronically-timed vertical-travel focal-plane shutter selects the speed automatically; there is no full manual speed dial in normal use. The viewfinder omits a numeric speed scale, instead using coloured lamps to indicate under, over or correct exposure, which reflects its beginner focus. Because exposure is electronically controlled, the body depends on its batteries to meter and fire correctly.
The MV suits students and newcomers who want a light, straightforward SLR and are content to work in aperture-priority. Its small M-series body and modest weight make it easy to carry for travel and everyday photography, and the simple lamp readout keeps operation uncluttered. The trade-off is limited manual control, so it appeals less to those who want to set shutter speeds directly.
As a used purchase, check the foam light seals and mirror-damper foam, which perish with age on M-series bodies and cause light leaks or a sticky mirror. Confirm the meter reacts to changing light and that the aperture-priority automation gives sensible speeds, since the shutter is battery-dependent and will not run correctly with weak cells. Inspect the shutter for even exposure across the frame, check the viewfinder lamps light, and work the film advance and rewind to feel for smooth, positive movement. Look through the prism for haze or foam residue.
