The Minolta 9xi was, when released in 1992, an advanced 35 mm single-lens reflex camera design. According to the company, it incorporated the world's "fastest autofocus system", had a maximum shutter speed of 1/12000 of a second, and had a 14-zone metering system. It has a shooting speed of 4.5 frames per second without the additional motor pack, a shutter speed of 1/12000 of a second due to carbon-reinforced shutter blades, a pentaprism, and it is compatible with xi zoom lenses having a "power zoom function".

Design

The Minolta 9xi has smoothed contours with buttons that were largely hidden or placed directly by the fingers controlling them.

Technology

The Minolta 9xi records at 5 frames per second without an external motor or battery pack, coupled with the four-sensor autofocus system that could continuously track not only horizontally but vertically and diagonally—even when an object came towards the camera. The autofocus system could focus at light levels of −1 eV and up to 19 eV (at ISO 100). It also used a 14-segment light metering system, variations of which have been used for many years in most Minolta cameras. It featured a 1/300 of a second x-sync flash synchronization with stepless shutter speeds from 1/12000 of a second to 30 seconds in Program and Aperture Priority mode. [1]

The camera could, without any external backs, bracket three exposures, each 1/2 a stop different (each way). It could control a wireless flash system. The 9xi was capable of detecting if the photographer had their eye placed against the viewfinder; it was named "eye-start".

Criticism

The 9xi was and is criticized for many design choices. One was that it used the "creative cards" system, with cards adding cost and being "impractical for the camera's intended market". Some functions (the "custom functions" card being the main offender) were already present in the 8000i's camera but only accessible by buying the card—this was seen as an attempt to "milk" the market. The camera lacks a built-in flash, which was seen as an attempt by Minolta to appeal to more professionally inclined photographers.

The camera was also criticized for its heavily "computerized" interface, with few buttons and many functions only accessible behind the card door.

The 9xi used both the older Minolta AF lenses and the xi-series lenses. Some of the new xi lenses had a new "powerzoom" function where the zoom ring electronically zoomed the lens via a motor. Lastly, the 9xi lacked a vertical grip, only having a "battery grip", while adding support for AA batteries.

<span class="mw-page-title-main">History of the single-lens reflex camera</span> Aspect of photography history

The history of the single-lens reflex camera (SLR) begins with the use of a reflex mirror in a camera obscura described in 1676, but it took a long time for the design to succeed for photographic cameras. The first patent was granted in 1861, and the first cameras were produced in 1884, but while elegantly simple in concept, they were very complex in practice. One by one these complexities were overcome as optical and mechanical technology advanced, and in the 1960s the SLR camera became the preferred design for many high-end camera formats.

The Minolta A-mount camera system was a line of photographic equipment from Minolta introduced in 1985 with the world's first integrated autofocus system in the camera body with interchangeable lenses. The system used a lens mount called A-mount, with a flange focal distance 44.50 mm, one millimeter longer, 43.5 mm, than the previous SR mount from 1958. The new mount was wider, 49.7 mm vs. 44.97 mm, than the older SR-mount and due to the longer flange focal distance, old manual lenses were incompatible with the new system. Minolta bought the autofocus technology of Leica Correfot camera which was partly used on the a-mount autofocus technology. The mount is now used by Sony, who bought the SLR camera division from Konica Minolta, Konica and Minolta having merged a few years before.
