The

5,.UIOIII

Auxiliary Fish-Eye lens can be used successfully with just about any camera from 8mm
movie to 8X 10" view! In conjunction with normal focal length lenses, the Auxiliary Fish-Eye pro-
duces the typical circular Fish-Eye format with 180· coverage. The afocal auxiliary design of the

.$'IUIOII

Fish-Eye has many distinct and unique advantages over"prime"Fish-Eye lenses. Among

them:

*

An almost universal adaptability to a wide va rietyof cameras and prime lenses.

*

The ability to function with various focal length lenses, yielding, in each particular co mbination, a
resultant focal length of .15X the prime focal length. Example: 50mm focal length is converted
to 7.5mm, 135mm is converted to 20.25mm and so on.

*

The normal camera viewing system is used, so that with SLR c arne r a s , the mirror need not be
locked up, out of the way, and focusing and composing is done normall~'on 'the groundglass in the
usual manner.

*

In conjunction with the focusing mount of
the prime lens, objects as close as

+"

from the front of the Fish-Eye can be
brought into sharp focus.

speed too slow), some zoom lenses (both dia-

may be unsatisfactory). prime lenses into
