Olympus OM-10 manual What batteries should I use?

last for about a half year, and the silver oxide batteries for about one year. When the temperature is extremely low.

Q: I pressed the shutter release button with the selector dial at the "OFF" position. Will the photograph be properly exposed?

A : Even at the "OFF" position, the camera's circuits will be activated for a proper ex- posure. Recommended to develop the film

andsee.

Q: When set at the "AUTO" position, the actual shutter speed is much slower than the one

indicated in the viewfinder. Why does this happen?

A : If film is not loaded or the film surface is not properly positioned behind the shutter, the speed will be slower than that indicated in the viewfinder.

Q : What batteries should I use?

A : Use two 1.5V alkaline-manganese batteries LR44 (A76) or two silver oxide batteries SR44 (Eveready EPX-76 or equivalents). Batteries of a different type (1.3V mercury batteries) cannot be used, though they may

be of the same size.

Q : A shadow appears darkening the central area of the viewfinder. Why does this happen?

A: This is quite usual when a lens with a maxi- mum aperture smaller than F5 is mounted on the camera, and the preview button is pressed with the diaphragm closed down

beyond F5. There is nothing wrong with

the microprism.

Q: If I return the selector lever to the ON posi- tion, while the self-timer in operation, what

will become of the shutter?

A: The shutter will be released. After the use of the self-timer, make it a point to return the selector lever to original position.

Q : While I was operating the Winder 2, the light in the viewfinder went out... why?

A: The light goes out in 90 sec. even the selector lever is ON, in order to save the batteries from unnecessary consumption. Touch the ac- tivator switch lightly, and the light is on again.
