Olympus OM-System S Zuiko Auto-Zoom 100-200mm f/5 lens Another inexplicable miss for Kadlubeks Objektiv-Katalog, which does not list it. It's another of those 'can't pass up a bargain' stories. On another thread somebody asked for recommendations for lenses for an Olympus OM-1 series body. I made some suggestions but got curious what the lenses I had bought last year were going for now, so over to the KEH site. There it was. A BGN 100-200mm f/5 lens for only $31. Since that was only a "two-pizza" buy, I thought what the heck, and besides I was curious about the BGN rating. Well, it came in only a couple of days (I'm not all that far from GA, where KEH seems to be located) and when I opened it up, it looked close to "new, old stock' in appearance to me. If this one is any indication, KEH really is very. very conservative in their ratings. It was clean, the white lettering un-besmudged, and everything worked smoothly. By the way, Zuiko 瑞光 seems to mean 'auspicious light', and this one lives up to the name. There are good discussions of the lens at the Mir site ( http://www.mir.com.my/rb/photography/hardwares/classics/olympusom1n2/shared/zuiko/htmls/100200mm.htm ) and pictures of its results at other sites like ( http://www.photosig.com/go/photos/browse;jsessionid=aRb7Fgd2Aik4EElkm3?id=36694 ). This was another 'bargain' lens for Olympus. It was introduced sometime in 1981-2 -- B&H in their ad of March 1982 list it as 'new' with a call for price. By June of 1982 they listed its price as $169, less than half the price of the 85-250mm f/5 (at $389).
