The Minolta 9000 AF (in the USA: Minolta Maxxum 9000 AF , in Japan: Minolta α-9000 ) is a professional autofocus - single lens reflex camera for 35 mm film , which was introduced by Minolta in 1985 . It is the only AF system SLR with manual film transport ever made. The camera holds various records and has a number of unique features.

The development of the Minolta 9000 was already completed before that of the Minolta 7000 . For marketing reasons, however, the 7000 was brought onto the market first and is therefore generally considered to be the very first AF-SLR (which is not entirely correct if you consider the Nikon F3AF (1982/1983), the Pentax ME-F, an early one Canon study or the Yashica Contax prototype 137 AF presented in 1982, the latter even also with passive autofocus based on phase detection of partial images on a CCD (instead of IR AF) and with a housing-based AF drive (instead of motors in the lenses)). The Minolta 9000 AF is certainly the first professional SLR camera that is embedded in an extensive range of AF accessories that has been almost completely redesigned for this camera (and its sister models).

Features and equipment

The camera housing of the 9000 is characterized above all by its robust all-metal construction, only the pentaprism is not completely metal-encapsulated. The shutter offered an exposure time of 1/4000 second, which was extremely short for the time, as well as a synchronization time of 1/250 second. The camera has the usual range of automatic exposure systems ( automatic program (depending on the focal length), automatic shutter , automatic aperture and manual operation), all program parameters are fully shiftable - neither of which can be taken for granted when they appear. Center- weighted integral metering and spot metering are available as exposure metering methods; The latter is supplemented by two special modes, light and shadow measurement , which, in conjunction with the exposure lock button (AEL), correct the exposure by +2.3 EV or -2.7 EV. In connection with the optional control back panel Program Back Super 90 (PBS-90), multi-spot measurements, optionally with automatic weighting according to average (AVERAGE), mean value (CENTER), highlight (HIGHLIGHT) and shadow (SHADOW) are offered, as well as user-definable ones Program curves.

Further features are interchangeable focusing screens, a detachable and disengageable dimming button with continuous aperture measurement until the shutter is released (not identical to the so-called final check system of earlier cameras, which even continues to measure until the shutter is opened), viewfinder illumination and a built-in eyepiece shutter to protect against extraneous light.

The camera is embedded in Minolta's AF camera system, which offers an extensive range of AF lenses (Minolta A-bayonet), system flash units, as well as camera-specific and system accessories, including a motor drive ( MD- 90 ) as well as a winder ( AW-90 ), a long film magazine for up to 100 recordings ( EB-90 ) and an early forerunner of a digital back wall , then still called still video back ( SB-90 / SB-90S ) with one resolution of 380,000 pixels and records the data on mini disks. However, this was only available in Japan.

AF model range

Alongside the Minolta 7000 and Minolta 5000 , the camera belongs to the AF series and thus to the first generation of autofocus cameras . The name Dynax was only introduced in Germany with the i-series ( 1988 ff.); in the USA the AF series was already marketed under the product name Maxxum .
