The '''[[Minolta]] 7000 AF''' is a historically significant camera, as the first popular [[autofocus]] [[SLR]] camera.  
Known as the '''Maxxum 7000''' in North America and '''a-7000''' (Alpha 7000) in Japan.  
This camera heraleded the era autofocus camera, and was followed by the professional [[Minolta 9000]] and the entry-level [[Minolta 5000]] shortly.  Minolta took the bold decision to introduce a whole new mount lens to accomodate for the needs of AF (&alpha; - Mount), this mount had a larger diameters and electronic contacts.  This mount lens is used up to the Sony-&alpha; DSLR cameras.

Autofocus had been tried for a while before the Minolta 7000, the ''[[Konica C35AF]]'' and the ''[[Polaroid SX-70]] Sonnar '' introduced in 1977 and 1978 respectively were the first practical cameras with autofocus.  Other companies such as [[Bolex]], [[Nikon]], [[Canon]], [[Pentax]] and [[Olympus]] had experimented with self-contained auto-focusing lenses that worked with their existing cameras and used their existing lens mounts. In 1983 the Minolta 7000 was preceded by Nikon's professional [[35mm]] SLR Nikon F3AF with built-in through-the-lens contrast focus detection<REF>Nikon F3AF, presented in 1983 together with a portrait AF Nikkor lens and a tele AF Nikkor lens, see [http://www.mir.com.my/rb/photography/hardwares/classics/nikonf3ver2/f3afbasic/index.htm Modern Classic SLRs: Nikon F3AF]</REF>. Minolta burst onto the scene in 1985 with their own in-body auto-focus camera system and changed the SLR camera market forever by having made the technology affordable for [[photography]] amateurs. 

Minolta took the decision to make a new lens mount, replacing the venerable SR/MC/MD mount.  This mount called Minolta A (Alpha) needed a larger diameter bayonet, and electrical connectors on the side to achieve full control of the lens.  Minolta also decided to put the electrical motor for focus in the camera using a physycal coupling to the lens.  This kept the cost of lenses low, and helped minimize noise.
This was not just a manual focus camera with autofocus added.  It was truly a revolutionary camera in that it redefined what an SLR was with the addition of computer chips in the camera body, lenses, and accessories.  These controlled the camera functions for optimal results.  For example, when a lens was mounted, its ROM chip would access the camera's CPU to optimize the program for that lens, and on-camera flash heads zoomed automatically with changes in focal length.  This level of sophistication had not previously been brought to market.  A built in motor drive and other automated features set the standard for other manufacturers.

The success of the AF innovation was such that and in rapid succession the company released three cameras: the entry-level [[Minolta 5000|5000]], the 7000 and the professional [[Minolta 9000|9000]]) and dozens of lenses, flashes, and accessories to make a completely new fully featured AF system. For the next couple of years Minolta autofocus film cameras dominated the market.

In addition to autofocus, the Maxxum 7000 had manual, aperture priority, shutter priority, and program modes. Knobs and dials were replaced with pushbuttons and internal and external liquid crystal displays (LCD's).  Popular with many new buyers, the LCD displays were disliked by some photographers used to the older controls, which lead to the pro version of the camera, the 9000, relying on more mechanical controls.  The new camera body utilized a large amount of plastic composites which also came in for both praise and criticism.  Minolta had a history of not disguising its plastic construction as had other manufacturers (for example the popular [[Minolta X-700|x-700]]).  7000's were durable cameras.

The camera was sold either with a Minolta AF 50/1.7 ($329.95) or a  Minolta AF 35-70mm/4 zooom with macro switch ($399.95).<REF>Bob Schalberg. Minolta Maxxum - A full autofocus SLR system that really works. Popular Photography March 1985, page70 </REF> Its zoom setting ring served in macro mode as manual focusing ring.

Early Maxxum 7000 cameras were inscribed "MAXXUM 7000" with a crossed 'XX'. The oil company Exxon considered this a violation of their trademark, as the XX in their logo was linked in a similar fashion. As a result, Minolta was allowed to distribute cameras already produced, but was forced to change the stylistic XX in Maxxum and implement this as a change in new production. All Maxxum cameras to this day have had regularly scripted 'X'.

Unfortunately for Minolta, its autofocus design was found to infringe on the patents of [[Honeywell]], a U.S. corporation. After protracted litigation, Minolta in 1991 was ordered to pay Honeywell damages, penalties, trial costs, and other expenses in a final amount of 127.6 million dollars.<REF>Article, "Minolta Credit Rating Downgraded by Moody's", July 11, 1992, NY Times</REF>

When Pentax and Nikon entered the autofocus segment, both utilized a similar passive array AF system as Minolta, but decided to retain compatibility with their existing manual-focus K and F mounts respectively. Canon, like Minolta, chose to change their mount completely, introducing the EOS 600-series a few years later, breaking the compatibility with the former FL and FD lens mounts. Like Canon, Minolta's decision to orphan its manual-focus mount cost it the support of some loyal customers, but in so doing, it also gained some new customers.

In 1987 Minolta presented another pioneering product, the video [[CCD]] camera back '''SB-70''' to convert the camera into a 307.000 [[Pixel]] still camera based on analog video electronics. The camera back wrote its image data onto special 2" floppy disks. The camera back worked with a VHS-like analog imaging and recording technology, with a small crop factor 2 video CCD chip. One disk could store 25 or 50 images, depending on the chosen image quality.<REF>[http://www.mhohner.de/sony-minolta/onebody.php?id=sb-90 SB-70/SB-90 camera back data] at M. Hohner's</REF>
