The Olympus OM-707 was released by Olympus in 1986, and was their first attempt to make a fully autofocus SLR body. On some markets, it was called OM-77.

In 1985 the Minolta 7000 had shown the way to a usable AF SLR, after various unsuccessful attempts like the Pentax ME-F, the Olympus OM-30, the Canon T-80 and the more serious Nikon F3AF. The other makers would follow, with the Nikon F-501, the Canon EOS 650, the Olympus OM-707 and the Pentax SF-X. The OM-707 was the least successful of all. It maintained the OM bayonet mount and could mount all the Olympus OM lenses, but the new lenses specially designed for the autofocus did not have any manual focusing ring. This was not acceptable because the first autofocus systems were not so satisfying and there were many cases when manual override was necessary; Olympus' solution to this was to include a 'Power Focus' feature; a sliding 'shift knob' on the rear of the camera controls the focus with relatively good accuracy - though not to the same accuracy as a manually focused lens offers. This feature outlived Olympus' autofocus, to reappear on the OM-101. The OM-707 also dropped compatibility with nearly all the accessories that made so much for the success of the OM system. The OM-707 generally lacked all the features of a top range camera, and was aimed at the middle range market, like the OM-10.


The OM-707 had one other claim to fame: it was released as a partner to the F280 stroboscopic flash, syncing with this up to 1/2000 of a second. This flash/camera combination was reportedly the first in the world to offer such high speed syncing. The F280 also features a high-power AF illuminator lamp to aid low light focussing.


Another 'accessory' released for the OM-707 was the option of two grips with which to hold the camera. The Power Flash Grip 300 is powered by 4x AAA batteries and features a built-in pop-up flash, the alternative Power Grip 100 is again powered by 4x AAA, features no flash, but is far less bulky to operate. Both grips feature the shutter release switch; without a grip attached the camera is unusable and un-powered.


The market failure of the OM-707 led Olympus to take the problem in another way. They made one last camera using the autofocus/powerfocus lenses, the OM-101 and then began to develop the IS series bridge cameras. Today Olympus continues this strategy of producing cameras somewhat different from the other makers with the Four-Thirds and 'E' systems.
