Ultra-compact fully mechanical Pentax SLR from 1976 with SMC 50mm f/1.7, one of the smallest serious film cameras.
The Pentax MX paired with the SMC Pentax 50mm f/1.7 is a fully mechanical compact SLR kit from 1976 that represents the pinnacle of Pentax's miniaturisation philosophy. The MX is one of the smallest full-featured mechanical SLRs ever produced, with an all-metal body barely larger than some compact cameras.
The camera features a fully mechanical horizontal-travel Seiko shutter with speeds from 1 second to 1/1000s plus Bulb, operating without any batteries. The viewfinder provides 95% coverage with a bright Microprism focusing screen, and the built-in centre-weighted meter uses LED indicators rather than a match-needle for clear visibility in low light.
The SMC Pentax 50mm f/1.7 is a compact, sharp standard lens with Super Multi Coating for excellent contrast and flare resistance. The seven-element optical design delivers pleasing rendering with smooth bokeh, and the fast f/1.7 aperture provides a bright viewfinder and useful low-light capability.
The Pentax MX with 50mm f/1.7 is a highly prized kit on the used market, loved by photographers who appreciate the combination of full mechanical reliability, compact size, and excellent Pentax optics. The MX's diminutive dimensions make it one of the most portable serious film SLRs ever made.
