That's quite unusual: these lenses are a bit later than some of the other Schneider LTM offerings, generally dating from the middle 1950's, by which time JSK was coating all their lenses, to my knowledge. This lens and the 3.5/135 Tele-Xenar were praised by the professionals of the day for their fine colour saturation. Today, the rarity of all these JSK LTM lenses makes them highly sought after; you could swap you lens even, I warrant, for a 2.8 Summaron if not for a good user Summicron. I'm not certain of the design and my Kingslake is ALWAYS at my other site. But the Biogon patent expired in 1952 or thereabouts -- just about the time the Xenogon appeared -- and Jos Schneider was never above a bit of pilfering Carl Z's better concepts, as they did the Xenotar from the Planar. So your guess might be right, and the Xenogon MAY have a formula similar to that of the Biogon. Marc msmall@roanoke.infi.net FAX: +540/343-7315 Cha robh bas fir gun ghras fir!
