Operation Precautions

Shooting Precautions

1. Focus first using the controls on the scope you are using, then make fine adjustments with 

the camera's AF function.

2. If you cannot focus on the subject, lock the AF by pressing the shutter release button 

halfway, then set the focus while viewing the LCD monitor.

3. With high-magnification shooting, focal depth is low. Be sure to focus carefully.
4. With high-magnification shooting, you can prevent vibration by using a cable release, self-

timer or remote switch.

5. If you notice external light on the monitor or image (picture), use a shield such as a black 

cloth to prevent light entering between the mount and lens of the camera.

6. Set in either "P" (Programmed) or "A" (Aperture-Priority) mode.
7. Camera position may become misaligned during camera operation. Before releasing the 

shutter, adjust the camera if necessary.

Shooting position:

Screw the camera block fixing fixing 
screw

 tightly.

Viewing position:

Release the camera block fixing screw ④ 
to open the camera block by 90 degrees. 
The camera block is prevented from being 
opened wider than 90 degrees by a spring 
stopper.
When moving the camera block, please 
hold the camera block handle

. Holding 

the camera may result in misalignment of 
the camera's position.

CAUTION: Depending on the type of camera, its position, or zoom setting, vignetting may occur. If vignetting does occur, carefully adjust the bracket 

position. Vignetting may not completely disappear.

CAUTION: When replacing batteries or recording media, please remove the camera from the connected equipment. Then re-attach the camera and confirm

6. Adjust the camera's position horizontally and fix it so that the lens aligns with the center of the camera mount. (Camera fixing screw ⑪ ) (Fig.6)
7. Adjust the camera mount ⑩ vertically (Camera mount height adjustment screw ⑬ ):
  By rotating the camera mount height fixing screw ⑭ in a counterclockwise direction, the camera mount ⑩ can be adjusted. Position so that the lens aligns 

with the center of the camera mount. Fix its position with the camera mount height fixing screw ⑭ . (Fig.7)

8. While watching the monitor display, adjust the horizontal level of the image by rotating the bracket. (Bracket fixing screw ② )
9. Check if vignetting occurs, across the entire zoom range: 
  While watching the monitor display, check if vignetting or shadow is visible at the four corners. If vignetting occurs, re-adjust the camera position (back 

and forth/horizontally/vertically) (Camera fixing screw ⑪ ) (Camera mount fixing screw ⑫ ) (Camera mount height adjustment screw ⑬ ) (Camera mount 
height fixing screw ⑭ ) so that;

  ・Vignetting and/or shadow are reduced or disappear.
  ・Vignetting and/or shadow are evened out at the four corners. Depending on the conditions, they may not be completely evened out.
  ・The closer the end of the lens moves to the eyepieces of the scope or lens of DS mount, the lesser vignetting and/or shadow will appear.
  Make sure the end of the zoom lens does not hit against the eyepiece of the scope or lens of the DS mount during zoom adjustment.
10. Place the cable release over the center of the shutter-release button. (Fig.8)
    a) Screw the cable release into the cable release socket ⑨ .
