4 TROUBLESHOOTING GUIDE

Symptom Suggested Remedy

Vignetted

Images

Using 35mm Nikon or Canon film cameras

it is normal for some vignetting to occur on

the left and right side of the image. Using

Nikon or Canon Digital cameras having a

sensor size of 5 Meg or larger can expect

some vignetting. Smaller sensors will

produce full frame imaging. Using Sony

and other non-removable lens cameras will

experience a vignetted image when the

camcorder zoom is at its widest position.

Zoom the camera until the image fills the

screen.

Image is out

of Focus

Using SLR type camera, focus normally

using the cameras lenses. Using Sony and

other non-removable lens camcorders

require the camera to be set in the manual

focus mode. Set the objective lens at a

known distance (5 meters) and turn the

camera lens ring until the image is sharp.

You do NOT need to adjust the camera

focus ring again. Focus only with the

objective lens.

Image is too

Dark

It is important to understand that all night

vision devices amplify the available light. If

the ambient lighting conditions are very

low, it may be difficult to obtain a

satisfactory shutter speed to hand hold the

camera. Make sure the lens aperture is set

to its widest position (ex. F/1.4). In

conditions where the camera wants to shoot

at slower than 1/30 second you should

check the ISO setting. Film cameras require

a film with at least and ISO of 1000 and

digital camera require a minimum ISO of

800. You should increase the ISO on digital

cameras when needed to shoot at 1/30

second.

Auto Focus

Not

Operating

The auto-focus systems on most cameras

use a variance of contrast to focus. In low-

light conditions, the contrast level is very

low and the auto-focus systems may not

operate efficiently. On Nikon camera only,

the Auto-S lenses may auto-focus, non-

Auto-S lenses will not auto-focus under any

condition. Canon EOS lenses may auto-

focus and the Canon XL 16X lens will auto-

focus. It is generally faster to manually

focus these cameras.
