Introduced in 1985, the Maxxum 9000 (otherwise known as the Alpha 9000) was the first professional auto-focus 35mm SLR made by Minolta. It was actually finished before the Maxxum 7000, but its launch was delayed in order to allow the 7000 to go first. Otherwise, the 9000 would also hold the distinction of being the world's first auto-focus capable SLR.
The Maxxum 9000 was aimed at the professional market and features a variety of high-end capabilities. It is capable of both center weighted and spot metering that can compensate for highlights and shadows. It also has off-the-film flash metering, as well as metered fill-flash. The Maxxum 9000 has four exposure modes: program, shutter priority, aperture priority, and full manual. It boasts a shutter speed range from 30 seconds up to 1/4000 that is stepless in the automatic exposure modes. It has a flash sync of 1/250th.
Several components on the 9000 interchangealbe, allowing a high degree of customization to the camera. The user can change focusing screens and film backs. Minolta even made a CCD film back that was capable of recording a 0.38 megapixel digital file. The accessory motor drive is capable of a respectable 5 FPS.
The camera uses the Minolta A-mount auto-focus lenses, a line of lenses that continued into the digital market.

Minolta Maxxum 9000 - Iron Man
When introduced in 1985, the Minolta Maxxum 9000 was Minolta's first professional auto-focus SLR. This camera influenced the design of succeeding cameras for decades to come. Curiously enough, it may be the only auto-focus SLR with manual film advance. Weird, but okay.
Let's talk about all the metal in this camera as a means of demonstrating just how well it was built. The body of the Maxxum 9000 is made from die-cast aluminum alloy; it's light and strong. This includes the mirror box and front plate as well. The camera's base is stamped brass. Tack on a stainless steel lens mount secured at six different points... The camera is filled with gold as well. Yes, gold. Minolta eliminated as much internal wiring as possible, replacing wires with gold-plated pressure contact points. There are also nine gold-plated switches. The film advance mechanism is also steel, with bronze bushes. The shutter is aluminum alloy. To top it all off, the actuating arms connected to those aluminum shutter blades are titanium.
If you have been looking for a great AF 35mm SLR, particularly one in the Minolta A-mount, you'll have a hard time finding a better candidate.
