Electronically controlled stepless shutter speeds from 1/1000 to 1 second for automatic modes plus stepped speeds from 1/1000 to 1 second plus “B” in metered manual mode. “X” sync setting for 1/100 sec, plus fully mechanical operation at “O” (1/100 sec) and “B”. Completely electronic automatic aperture control in shutter priority mode. Final check metering system (after stopping the lens down the camera performs a final check to ensure that the exposure will be correct). This was later also used in the Minolta X-700. Very bright acute-matte viewfinder screen with details of selected aperture and shutter speed, so no need to take the eye from the viewfinder, even in metered manual mode. A range of interchangeable screens was available (see here). Vertical traverse metal blade focus plane shutter for quiet operation, and also enabling a fast 1/100 sec flash sync speed. This sync was the fastest of the Minolta Manual focus bodies, and was nearly twice as fast as the later X-700. Silicon photocell TTL centre weighted meter, measuring at full aperture for display then at taking aperture for exposure. Automatic exposure range EV1 to EV18. Can be used without batteries in fully mechanical mode at B for long exposures, or at “O” for 1/100 sec. This feature was included because photographers had traditionally been used to mechanical cameras, and there was still some hesitation at relying on a battery. What it means now is that for extremely long exposures the battery can be removed, resulting in zero current drain. Later models, such as the X-700 had a maximum long exposure time of about 2 hours, due to the fact that battery power was required to keep the mirror up. Remote shutter release that will accept both electronic and manual shutter releases. Unlike later cameras like the X-700, the XD7 uses a full metal body construction. Can be used with the Autowinder D for motor driven sequences of up to 2 frames per second. Exposure adjustment lever for up to two stops over or under exposure from the metered setting. Depth of field preview button. Built-in eyepiece shutter for tripod use (won't mess up your metering). PC connection for studio flash use. Film “safe-load” indicator. Self timer (adjustable from 2 to 10 seconds).
