The Minolta X-300 is a 35mm manual focus SLR based on the MD mount, and which was produced between 1984 and 1990. The X-300 was also marketed as the X-370 in the U.S. and Canada.
The camera has an electronically-controlled cloth-curtain focal plane shutter. The shutter can be manually controlled stepwise from 1 second to 1/1000 via the covered dial on the top of the camera, but in aperture-priority mode, the shutter is capable of stepless speeds and can open for up to four seconds in low light.
The meter is mounted in the pentaprism, and gives a center-weighted average light value.
