To commemorate its 50th anniversary, KMZ issued a special edition of Zenit-122 camera in 1992. Camera comes in titanium grey ABS plastic with gold silkscreened inscriptions. Even a serial numbers has special markings - its prefixed by the anniversary number "50". Camera bottom is signed "Made in Russia".
Following the Bill Parkinson's information, there were 6,541 of these cameras made between 1992 and 1994, but many doubt this as these cameras do not show up in collections or on the marketplace very often and are considered quite rare. Other numbers like "only 300 cameras" are stated by some collectors.
