Lomopedia: Minolta Maxxum 7000

1

The title of the world's first autofocus SLR camera belongs to Minolta Maxxum 7000, introduced in 1985. Read on to find out more about this beautiful and revolutionary camera that was among the most advanced of its time!

The Maxxum 7000 — 7000 AF in Europe and Alpha 7000 in Japan — was introduced by Japanese camera maker Minolta, a move that cemented its spot among the so-called Big Five 35mm SLR camera makers in Japan. While its competitors were already experimenting with auto-focus systems prior to the Maxxum 7000, Minolta was the first to offer the first true AF SLR system with a body-integrated AF design. This means that the Maxxum 7000 had its AF sensors and focusing drive inside the camera body, which mechanically drives the aperture and focus from the camera body to the lens mount.

Aside from this revolutionary feature, the Minolta Maxxum 7000 also came with a new lens mount (the A-system), motorized film advance, and a lighter and cheaper plastic body.

    Nice review, Ive got one of these and I really quite like it, the autofocus is a bit off but otherwise its a fairly competant machine (and customised in my case with a vintage style leather grip), only gripe with it is finding cheap lenses as all of the pesky Sony owners nick them for their DSLR's, still I hope to get a good prime for it one day and I cant exactly complain as it was a freecycle find complete with a sigma zoom lens.
