The Pentax MZ-10, sold as ZX-10 in the USA, is an autofocus SLR-camera for 35mm film introduced in 1996. It is an early and lower priced model of the MZ/ZX series [1]. It was available in all black or silver/black, with or without data back or panorama function (switching to 13×36 frame format by a mask). Though the bayonet mount of the MZ-10 is made of plastic, it features the full KAF2-mount.

Besides the usual exposure modes like metered manual mode, shutter-priority AE mode and aperture-priority AE mode, the MZ-10 offers 5 picture modes which are optimized program modes for certain situations: green operation mode, portrait program mode, landscape program mode, close-up program mode and action program mode. These modes can be selected manually or automatically by the camera depending on the focal length and focus distance, this function is called smart picture mode. The selected mode is indicated in the viewfinder and on the LCD-panel beside the shutter button.

Lens compatibility:[2] Generally the MZ-10 is intended to use with SMC-F and SMC-FA-lenses. Manual focus K- and SMC-M-lenses and even adapted M42 screwmount lenses (M42 lenses with stopped-down metering, therefore they must be capable to stop down by itself) can be used in manual mode and aperture-priority AE mode, thus no picture modes are available; furthermore the camera switches from six-segment exposure metering to center-weighted metering. Lenses without aperture ring (equal to lenses with aperture ring set to "A") like SMC-FAJ or some SMC-DFA-lenses can be used in aperture-priority AE mode or a picture mode only; it is not possible to set a certain f-stop manually. The MZ-10 offers limited power zoom functions with appropriate SMC-FA zoom lenses, e.g. motorized zooming, but no advanced facilites like image size tracking.

The MZ-10 is intended for amateur photographers, so it shows some deficiencies. It lacks in a DOF-preview, there is no multi exposure function, mirror lock-up, spot metering or dioptric adjustment. The non-interchangeable viewer-screen has no focussing aids like a split-image spot.
