The ST701 has a stop-down, match-needle TTL metering system that uses two silicon photo diodes, and was the first camera design to abandon CdS cells in favor of a faster and more sensitive silicon photo-diode. Metering needle indicators are displayed in the viewfinder, which is exceptionally bright. The camera's focal-plane shutter has speeds of 1 to 1/1000 sec. The flash sync speed is 1/60. The camera has two connectors for flash, the top one is for FP and the bottom is for X. The finder screen has a microprism to aid in focusing. The camera's meter is powered by mercury batteries, but unlike many cameras of the time, it simply will not work at all with higher voltage modern batteries.
There were three versions of this camera. The image to the right is the first version and below are of the third version. The second version is similar to the first but the badging has been changed. The third version added a hot shoe and split-image rangefinder focusing spot. The ST701 was one of the first 35mm SLR cameras to feature a hot shoe.
