The first generation body is made of metal. It was launched alongside the Minolta Maxxum 9000 in fall 1985.[1] There is a focus limiter switch to speed up focusing. This lens and the Minolta AF 70-210mm f/4 lens are colloquially known as the "big beercan" and "beercan", respectively, by Minolta camera users because their shape and size closely match the proportions of a typical aluminum drink can used for beer.
The optical construction is changed and the metal body is replaced by a plastic body. Consequently, the lens is much shorter and lighter.
The second generation has a focus hold button. Starting from the third generation, this lens is produced in black or silver color.
The new (D) type supports ADI (Advanced Distance Integration) flash metering function.
After Sony purchased the Minolta Camera Division, this lens was re-released under the Sony brand. The Sony lens retains most of the Minolta design but comes with a new look.
