Undesirable objects for focusing
Although the auto focus function of the RE-450X is capable of focusing on most objects, objects such as
those listed below may present some difficulty. If this happens, focus the lens manually by pressing the
FOCUS button first and then the NEAR button or the FAR button.
1. Objects with a low reflection factor (such as a dark cloth, hair, etc.)
2. Intangible objects (such as candle light, smoke, etc.)
3. Objects having a glossy surface (telephone receiver, glassware, etc.)
4. Objects viewed through glass.
5. Objects with low contrast.
Use the backlight to project transparencies, such as OHP film and slides.

Film Projection
• Project the film to full monitor size by using the zoom button. If light from the
backlight appears in the monitor, the picture itself will not appear very sharp.
• If the color tone seems unnatural, adjust the white balance manually (see
page 13). If the auto focus function doesn’t operate accurately, focus the lens
manually.
• The illumination lamps and the backlight cannot be used at the same time.
