The Spiratone Auxiliar.v Fish-F,,ve is sup-
plied rvith an interchangeable rear custom
fitting rvhich matches the front threads or
ba.r'onet of a specific camera lens of -r'<lur
choice. These fittings are available  in
most popular siire threads including  3.tr,
35.5, {0.5, ;1.3, 46, .18, .X9, 52, 55, 5fi,
60, 62, and 67mm, plus various ba.r'onet
and series size fittinss.

Simplv screw the appropriate custom
rear fitting onto the back of the Fish-
E.ve. Thread or bayonet the Fish- E1'e
into the front of the camera lens.

Avoid mounting the F'ish- Eye with slip-
on or set screw adaptors, since these
tend to be precarious and shift the attach-
ment off the optical axis.

ORIENTING THE FISH-EYE
If the aperture scale of the Fish- Eve is
not centered in the upright position,
loosen the three set- sc rervs in the base
ring (Fig.1-@Jof the Fish-Eye,rotate  the
lens to the desired position and retighten
the set- screws.

OPERATING INSTRUCTIONS FOR THE SPIRATONE AUXILIARY
 FISH - EYE LENS.

 The Spiratone 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 18q' coverage. The afocal auxiliary design of the
 Spiratone Fish-Eye has many distinct and unique advantages over "prime" Fish-Eye len5g5. Among
 them:
 * An almo:.rt universal adaptability to a wide variety of cameras and prime lenses.
 * The ability to function with various focal length lenses, yielding, in each particular combination, a
    resultant focal length of .16X the prime focal length. Example: 50mm fo":rl length is converted
    to 8mm, 135mm is converted to 21.5mm and so on.
 * The normal camera viewing system is used, so that with SLR cameras, the mirror need not be
    locked up, out of the way, and focusing and composing is done normally on the groudglass in the
   usual manner.
 * In conjunction with the focusing mount of

 The Auxiliary Fish- Eye lens is suitable for
 virtually all types of cameras including 8mm.
 Super 8mm and 16mm, as well as 35mm
 movie cameras; T.V.' cameras; subminia-
 ture cameras; half size and regular size

The Auxiliary Fish- Eye lens is not recom  -
 mended for use with wideangle lenses (result-
ing diameter of circular image too small),
for lenses longer than 200mm (resulting
speed too slow), some zoom lenses (both dia-
meter of circular image and image quality
may be unsatisfactory), prime lenses into
which Fish- Eye cannot be screwed or bay -
oneted (slip-on fittings are not suitable).
lenses with a greatly recessed front element
(may cause vignetting due to increased dis-
tance between prime and auxiliary lens).

On SLR and other cameras with groundglass viewing screens, viewing is direct. With non- groundglass
cameras, the approximate field coverage can be estimated by holding the Auxiliary Fish- Eye in front of
one's eye-it will indicate the approximate field covered by the camera with the Fish- Eye attached.
An accessory viewfinder can also be used for this purpose.
On twin lens reflex cameras, the Fish- Eye can be shifted from the top lens for viewing and focusing to
the lower lens for actual shooting.
It is difficult to visualize the extreme angle of coverage of the Fish-Eye,even when using a reflex view-
ing system. The usual position of tripod legs, your hat, or even your own feet may show in the Fish-
Eye picture unless you take special care to avoid this.
FOCUSING.
While the Auxiliary Fish-Eye has no focusing mount of its own, with SLR and view camerasthe
focusing mount of the prime lens is effective in varying focus to objects from infinity to only l"  from
the lens. With the prime lens set to infinity, the depth of field of the Fish-Eye extends from about
3 feet to infinity. At smaller openings, depth of field at the infinity setting may extend to as close as
llfeet.  With non-reflex cameras, the infinity setting should be used at all times.
OPERATING THE DIAPHRAGM.
Always set the diaphragm of the camera lens to its maximum aperture (wide open). Rotate the dia-
phragm control ring of the Fish-Eye to the desired f stop- the f stop shown on the Fish-Eye dia-
phragm scale is accurate for that focal length setting, and no further compensation is required.
For optimum definition, an aperture setting of 2 or 3 stops below the maximum opening is recommen-
ded.

EXPOSURE.
 Exposure is determined in the usual manner, depending on the opening at which the diaphragm of the
 Fish- Eye is set. On cameras on which the Fish- Eye covers all or part of the built- in electric eye, the
 exposure mechanism must be operated manually. When measuring exposure by means of a separate
 meter, it is important to keep in mind that the average meter covers an angle considerably narrower
 than that covered by the Fish- Eye, and that the subject may include areas of greatly varying bright  -
 ness which should be measured separatly, with such exposure selected to best record the most signifi-
 cant part of the subject within the total field.
On cameras with through- the- lens metering system, car:e should be taken that the meter reading
 area is within the picture field. Meters that integrate the entire groundglass image will give a false      l'
 reading unless the Auxiliary Fish- Eye is used with 135mm or longer lenses to yield an image cover'     inI
 ing the entire film format.                                                                                                                                                                                                        Il'
 When the Fish- Eye is used with shorter focal length lenses on 35mm through- the- lens meter reading
 cameras, a separate exposure meter should be used to establish correct exposure.           l

F ILTERS.
Custom 22.5mm screw-in filters may be attached to the rear mount of the Fish-Eye. Standard custom
screw- in filters for the front of the prime lens may also be used but the added extension created by
such use of a filter may at times cause vignetting.

CARE OF THE FISH- EYE LENS.
The extreme curvature and exposed position of the front element requires'dpecial care in handling and
 storing to avoid touching and damaging the glass surface. Keep the special cap on the Fish-Eye at all
times. except when actually shooting. Brush gently to remove dust and, if necessary, wipe the lens
with as light a touch as possible.
