4 TROUBLESHOOTING GUIDE
Symptom | Suggested Remedy |
Vignetted | Using 35mm Nikon or Canon film cameras |
Images | 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 |
| 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 | Using SLR type camera, focus normally |
of Focus | using the cameras lenses. Using Sony and |
| other |
| 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 | It is important to understand that all night |
Dark | 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 | The |
Not | use a variance of contrast to focus. In low- |
Operating | light conditions, the contrast level is very |
| low and the |
| operate efficiently. On Nikon camera only, |
| the |
| |
| 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. |
