Optex 200mm Macro for sale, rehoused version of Pentax-A* 200/4 ED Macro. PL mount
The Pentax-A* 200/4 ED Macro is one of the legendary Pentax lenses, with an almost mythical reputation. It is very difficult to find on the used market and I've even seen several for sale converted to Canon EOS mount.
As usual with Pentax manual focus lenses the Pentax-A* 200/4 ED Macro is very well built, with an all metal construction and a sturdy, removable tripod mount. The lens is provided with a hood of the built-in, sliding type and comes in a leather hard case. It takes 58mm filters.
The lens is a 10 element 9 group construction featuring ED (extra low dispersion) glass. The lens is a true macro lens capable of focusing down to life size (1:1) magnification. Results are razor sharp with best resolution I have ever seen in any 35mm SLR lens. Its not only brilliant when used as a macro lens, but even more so when used as an ordinarily telephoto lens focused at infinity. The lens also work exceptionally well with Pentax converters, giving you a 400mm macro lens with superb optical quality. There's very quality little difference between the apertures.
