"Berlin - 31 March 2001.
A Russian company, Zenitoptikpak, has just released a new zoom lens for
the more popular SLR's.
The ZK-16-600 f/1.2 Apo SVCW Apo Macro
Zoom range is 16 to 600mm all at a blistering fast f/1.2 with no
rotating front element. This is possibe due to advanced high
refraction/lo absorption glass developed for Cold War laser applications
(for which the Russians have always been highly advanced).
Weight of the lens is a reasonable 21 ounces with a fixed length of 9.5
inches.
AF is said to be crisp, fast and quiet due to the new subsonic variable
crest wave (SVCW) drive (a by product of military R&D in Russia during
the Cold War for an unspecified weapon system suspected to be part of
submarine propulsion systems)

What?????
No mention of a rectilinear/fisheye switch for use in the 16mm position of
the zoom?
According to the advance info leaked out about this lens, there is supposed
to be a rotating ring near the mounting flange that can be turned about a
quarter-turn with the zoom in the 16mm position. This would switch the
lens from rectilinear to fisheye. In the fisheye position it locks the
zoom ring. Before zooming out from 16mm position, the ring has to be
rotated back to the rectilinear position. With the zoom ring in any
position other than 16mm, the rectilinear/fisheye ring is locked in the
rectilinear position.
Darn! I was really counting on this feature . . . a unique ability to go
fisheye with a super-wide zoom. Hopefully it was just left out of the
rec.photo posting by accident!
