The Konica A4 is a 35mm autofocus compact point and shoot camera released in 1989. The design of this camera is the basis for the Big Mini series of cameras.
The camera's main body and hand grip area is a black or silver matte type plastic, while the rest of the front is a shiny black type. A version with date is also available. It features a 35mm f/3.5 lens comprised of 4 elements in 4 groups. The lens has a automatic cover that opens and closes based on the power state. The focusing is infrared type with a distance of 0.6m to inf. with a focus lock activated by half pressing the shutter release. A close-up mode is also available that reduced the focusing from 0.35 to 0.6m. The shutter is electronic with speeds of 1/3 to 1/500-sec. The exposure system is based on center-weighted design using a CdS measuring element with a range of 5 to 17 EV. The viewfinder contains bright lines for framing as well as marks for parallax correction for using the close-up feature. It has LED in the finder for focus/focus lock, close-up and flash state. Automatic flash is built-in with a fast 3 sec. recycle time. Flash can be used in automatic mode but can also be used in fill flash (On) mode or turned off competely. The self-timer is electronic with a blinking indicator and delay of 10 seconds. The film automatically advances the frames and auto rewinds at the end of the roll. The frame counter is LCD based and counted upwards. The camera is compatible with DX encoded film, but with non-encoded films it defaults to using ISO 100. It is powered by a CR123A lithium batteries.
