I vaguely recall that there are three Russian 500mm's, with the 500/5.6 more known than the 500/6.3. Might be the same basic lens, but one rated in F-stop (measured at 500/overall diameter) and the other rated in T(ransmission)-stop (measured at 500/effective diameter [sans donut]). Note that there is also a nice 300/4.5 Russian mirror available. Probably will buy one some time for infrared photography....no fussing with IR-correction....:-)) Btw Marc, have you successfully mounted one of those on a Leica R body? Since all these lenses are M42-mount, they officially shouldn't fit (R-register is larger than M42-register), but slop beyond infinity and being a tele might compensate for that. Do *thin* M42->Leica-R adaptors exist at all?
