Your new Catadioptric or Reꢀex mirror lens is a highly developed, computer designed product which uses  
the merits of both reꢀex optics and refraction optics. This gives you very sharp picture quality with less color  
aberration, which is considered the most harmful factor in the ꢁeld of telephoto photography.  
1. Required T-Mount  
A proper T-Mount adapter should be threaded onto the back of your lens in order to attach your lens to your  
camera.  
2. Mounting Your Lens to Your Camera  
The T-Mount is similar in design to the mount of standard lenses designed for your camera, and is coupled  
and removed in the same manner. To mount the lens, attach the T-mount adapter to your camera and then  
simply attach the lens to the adapter.  
3. Focusing the Lens  
Focusing is accomplished while viewing the subject through the viewꢁnder of your camera and rotating the  
focusing ring. Since the aperture is preset, you will ꢁnd under certain light conditions a shadow appearance  
on the split-image section of your focusing screen. In this case, simply focus on the edges of your subject  
with the outer center of your prism.  
-5-  
 
NOTE: In order to compensate focusing when normal positioning may be altered due to extreme  
temperature change, the focusing ring has been designed to allow rotation beyond the ꢀxed  
marks of the distance scale. To avoid mistakes, always focus while looking through the viewꢀnder.  
NOTE: No adjustments in focusing are necessary when taking infrared photography as required  
with normal lenses.  
4. Light and Contrast Control  
Since the reꢁex lens is not equipped with a diaphragm system, the use of ꢀlters plays an important factor in  
the control of light and contrast.  
5. Filters  
Normal (IA Skylight): This ꢀlter should be used when no other ꢀlters are necessary.  
ND 2X & ND 4X (Neutral Density): These ꢀlters control the passage of light since no diaphragm  
is provided in the lens. Exposure factor is 4X with a ND4X, so that the light intake through the  
lens is decreased as if a similar lens were stopped-down by 2 stops. Note that ND ꢀlters reduce  
light passage only, while the depth of ꢀeld is not changed.  
-6-  
 
Y52 (Yellow): This ꢀlter is used when taking black and white pictures. It also makes a blue  
background darker. It is quite eꢁective when taking shots of clouds on a blue horizon.  
056 (Orange): This ꢀlter makes blue or green color lines darker and yellow or red color lines  
lighter than they seem to the human eye. It is most eꢁective when stronger contrasts are desired.  
R60 (Red): This ꢀlter is used to make daytime scenery appear as night time scenery, or to  
emphasize and strengthen contrast. It is also necessary when taking infrared black and white  
exposures.  
NOTE: If the subject being photographed shows too much light or seems overexposed when  
measured by a meter or as indicated by an LED warning signal of the camera, then adjustment  
of the light intake can be controlled by using one of the ND ꢀlters. When using an R60 ꢀlter  
with an aperture preferred camera, an aperture adjustment of +0.5 to +1.0 is required.

6. Exposure or Aperture Adjustments with TTL Cameras  
Since the aperture of the reꢀex lens cannot be changed, the exposure is controlled entirely by the  
shutter speed being used. The speed dial is set according to your TTL reading. Cameras with  
automatic aperture and shutter priority will automatically set the right speed with their auto  
exposure mechanisms, with the exception of a few models which require manual function.  
With aperture priority or manual operation of your camera, the apropriate shutter speed must be  
adjusted using three neutral density ꢁlters in case of over exposure readings or if the camera’s  
LED warning light is activated. If your camera has a manual TTL system, then simply follow the exposure  
indicator in the viewꢁnder by compensating with the shutter speed. If there is excessive light beyond the  
shutter speed capability, then attach a Neutral Density ꢁlter to reduce the overall passage of light.  
7. Exposure or Aperture Adjustments on Cameras Without a TTL System  
When using a camera with no TTL system and only a normal ꢁlter, the exposure must be stopped  
down as indicated by the table on the following page to the shutter speed adusted as indicated  
by an exposure meter reading. So, for example, with a 300mm f5.6 reꢀex lens, the setting would  
be f5.6. If a Y52 ꢁlter is used in daylight, the stop down would be 1. Also, if the appropriate  
shutter speed is metered as 1/1000 seconds using a single exposure meter with an f stop of 5.6,  
then the shutter speed setting would be 1/500 seconds.

NOTE: Generally, if a 1/2 shutter speed adjustment is indicated to negative ꢀlm, a full stop should be taken.  
When a reversal ꢀlm is being used, disregard the half-stop setting and use a normal shutter speed.  
8. Depth of Field  
The area in acceptable sharpness in front of, and behind the subject in focus is called the depth of ꢀeld. The  
aperture selected and the distance of the subject as well as the focal length of a lens determines the depth of  
ꢀeld. Because of the long focal length of your lens, the depth of ꢀeld is narrow. For example, with a 800mm  
f8.0 lens, at a distance of 6 feet, the depth of ꢀeld is only 1/2 inch wide. It is recommended that you practice  
focusing with your lens before taking any serious pictures, especially in close up photography. Also, we  
recommend using a focus magniꢀer to help determine the depth of ꢀeld sharpness under extreme  
conditions.

9. Cleaning and Maintenance Tips  
A. The lens should always be capped when not in use. Only wipe with cleaning papers or  
cloth speciꢀcally made for optics.  
B. Accumulated dust should be blown oꢁ with a syringe or blower brush speciꢀcally designed  
for this purpose. To remove ꢀngerprints or smears, shred the end of a lens tissue and roll it to  
make a swab: dampen it with a lens cleanerspecially made for photographic optics and gently  
wipe the surface without applying too much pressure. If necessary, repeat using a new swab.  
To clean, start at the center of the lens using a circular motion and working to the edge of the  
lens for best results.  
C. When the lens is not in use, it should be stored in a cool dry place, or if not possible, then in  
a leather case with a silica gel packet, or aluminum case with polyfoam liner.  
YOUR LENS IS A HIGHLY COMPLEX PRECISION OPTICAL INSTRUMENT. IT IS INDIVIDUALLY ASSEMBLED  
BY SKILLED CRAFTSMEN. WITH PROPER CARE AND MAINTENANCE IT SHOULD GIVE YOU YEARS OF  
SATISFYING AND ENJOYABLE PHOTOGRAPHIC RESULTS.
