Originally posted by bdery To be fair, a lot of people use the term "zoom" to refer to a tele lens.
Early still "zoom" lenses were correctly and simply called "variable focal length" lenses. Their focus changed when you changed the focal length. The movie industry however needed to be able to zoom without changing focus, for obvious reasons, so the "zoom" lens was evolved and the idea was taken up for still cameras too. It takes some clever optical design to achieve this. Today most zoom lenses still change effective
aperture when you zoom, except for the more expensive ones.
So strictly, "zoom" means the ability to change focal length
and keep focus while doing so.

Originally posted by photolady95 I wanted a K1000 made in Japan, with the Asahi imprinted in the prism housing because that's what I started using when I went on to get my B.A in college. It was just a memorabilia thing to me.
I know that colleges recommended them to students where a camera was needed, and it was good advice. Sadly, Pentax (or their retailers) seemed to exploit this "captive" market and jacked the price up. I still have some price lists from around 1975 which show the K1000 costing more than an MX, even though an MX must have cost significantly more to manufacture.
