Minolta X700

The X-700, born in 1982, can be said to have integrated two of the most advanced technologies in camera manufacturing at that time: Program (P) auto exposure and TTL auto flash. The X-700 program first applied a 4:7 shutter aperture program ratio, which, when paired with a 50mm standard lens, matches the maximum aperture at a speed of 1/30 second or lower in low light environments; In high light environments, the aperture sharply decreases with the increase of shutter speed. TTL flash is a system that can directly measure the reflection of film plane and achieve automatic control of flash exposure, and it was also the most advanced at that time.
