Cult Classics in Third Party Lenses
„Vivitar 600m f/8 and 800mm f/11 Solid Cats
Vivitar also marketed a series of solid catadioptic or solid cats of one-piece glass construction. These mirror lenses were actually made by Perkin Elmer (of NASA space telescope fame). The 600mm f/8 and 800mm f/11 solid cats have achieved cult status as very compact (only 3.3 inches long), sharp, and super-rugged lenses. Their ruggedness is partially due to their solid, one-piece construction, unlike most current production mirror lenses. This solid one-piece construction design means the elements remain in the optimal fixed positions relative to each other, despite temperature changes or even professional use and abuse.
Weight was only 3 pounds on the 600mm and 800mm lenses! Yet these lenses could close-focus to 23 feet and 25 feet respectively (circa 1:9.3 and 1:8.5 respectively).
One thing to be wary of when buying these lenses is to be sure you get the oddball series filter size filter set, including the UV filter. The lens design requires a filter in the optical path. Be aware that to replace filters, you have to remove the lens, then remove the T-mount, then replace the filter. More modern mirrors have a rotating filter mount.
Most of the standard filters are for black and white photography. Obviously, a polarizing filter would have to be front-mounted, a rather painful financial proposition for such a large filter size. (Hint: Edmund Scientific sells sheets of polaroid material cheaply)
Today, you would be lucky to find these lenses for sale used, as most owners readily appreciate their technical and optical qualities. Few were sold originally because of the steep price tag ($634 in 1975 dollars translates to $1,971 in today's 1998 dollarettes). They quite literally don't make them like this anymore!“

Ok, eine EL2 - aber was sagt ihr zum Vorbau? Das ist ein wirkliches Trum und wunderbar wertig. Solid cat - alle Spiegel ohne Luft-Zwischenräume in Glas verbaut, heavy duty :-)
Klingt spannend !
Könnte mir vorstellen,daß diese Objektive,heute recht selten sind ?
Suche schon länger das Planfeld-Zoom 90-180 von Vivitar.
Wird aber leider nur selten angeboten.
Glückauf.

Werde lieber weiter auf Börsen ausschau halten :)
Glückauf.
