Manual Focusing; Film Projection - Canon RE-350 Instruction Manual

Manual Focusing

When trying to focus correctly or focusing on a particular point of three-dimensional objects, you can
achieve focusing by pressing the manual focusing buttons. The manual focusing is valid up to approx. 2-
inch (65mm) above the document table.
■ Undesirable objects for focusing
Although the auto focus function of the RE-350 is very accurate, objects such as those listed below may
present some difficulties. If the system cannot focus automatically, the AUTO FOCUS indicator goes off. If
this happens, focus the lens manually using 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.

Film Projection

Use the backlight to project transparencies, such as OHP films, photographic negative and positive films
and 35mm slides.
