The Minolta Maxxum 4 (Dynax 4 in Europe and Dynax 3 in "in Asia Pacific countries") 35 SLR camera was introduced in 2002. Konica Minolta has discontinued production of this model but maintains information on it in its website.
Capable of automatic focus, the Maxxum 4 has through-the-lens metering, a built-in pop-up flash and a hot shoe for flash. The shutter is an "electronically-controlled, vertical-traverse, focal-plane type." It uses infrared sensors to focus, so for this reason the camera's manual advises against using it for infrared photography.
