The Pentax M series cameras were noted for their compact size and are among the smallest 35 mm SLRs ever made. The Pentax MX was introduced in 1976 and was designed as a manual-only SLR system. It has a set of accessories that were mostly incompatible with the other M series cameras. It was very compact but had one of the largest and brightest viewfinders of any 35mm SLR. The MX was entirely manual and resembled the earlier KX in features.
