The Minolta 9000 AF is a professional Single-lens reflex autofocus camera, introduced by Minolta in September 1985. It was both Minolta's and the world's first professional autofocus SLR. It was called Minolta Maxxum 9000 in the USA and Minolta α-9000 in Japan.

As the first professional autofocus SLR system ever made, the Minolta 9000 AF sports of number of unique features translating the transition from electro-mechanic cameras to the generation of full electronic cameras. For instance, it is the only autofocus system ever made with a manual film transport rather than automatic electronic winding.

History[edit | edit source]

In the early 1980s, Minolta was developping several ranges of autofocus SLR cameras, with the Minolta 7000 aimed at the advanced amateur market, and the Minolta 9000 aimed at the professional market. Development on the Minolta 9000 was completed before that of the Minolta 7000, but for marketing purposes, the 9000 was held back and the 7000 was launched first in February 1985. For this reason, the 7000 is often considered to be the first ever aufocus-capable SLR (notwithstanding earlier SLRs retrofitted to incorporate autofocus capabilities such as the 1982/1983 Nikon F3AF; the poorly-performing Pentax ME F; and prototypes by Canon and Contax, such as the Yashica Contax 137 AF). In any case, the Minolta 9000 AF was the first professional SLR system featuring a wide range of autofocus-capable accessories.

Characteristics[edit | edit source]

The body of the Minolta 9000 is a robust all-metal construction, with the pentaprism being the only component not to be completely encased in metal. The shutter was capable of the then-extremely short exposure time of 1/4000 seconds, as well as of 1/250 second synchronisation.

The exposure meter provided the user with the usual range of automatic exposure modes: automatic, shutter priority , aperture priority and manual mode. As metering modes, it was capable of center-weighted integral metering and spot metering; spot metering could be further refined with light and shadow corrections, which used an exposure memory to correct exposure by up to 2.3 EV. Furthermore, an optional back "program back super 90" (PBS-90) provided multi-spot measurements, with optional automatic weighting by average (AVERAGE), mean (CENTER), highlight (HIGHLIGHT) and shadow (SHADOW), as well as user-definable program curves.[1]
