Information
z
The charger and AC adapter can be used in most home electrical sources within the range 
of 100 V to 240 V AC (50/60Hz) around the world. However, depending on the country or 
area you are in, the AC wall outlet may be shaped differently and the charger may require 
a plug adapter to match the wall outlet. For details, ask at your local electrical shop or 
travel agent.
z
Do not use commercially available travel adaptors as the charger or AC adapter may 
malfunction.
Select the lens that you want to shoot with.
Use a specified Four Thirds lens (Four Thirds mount). When a non-specified lens is used, 
auto focus and light metering will not function correctly. In some cases, other functions may 
not work either.
Four Thirds mount
Developed by Olympus as the lens mount standard for the Four Thirds system. These all-new 
interchangeable lenses featuring the Four Thirds mount were developed from the ground up 
based on optic engineering exclusively for digital cameras.
ZUIKO DIGITAL interchangeable lens
Four Thirds system interchangeable lens are designed to withstand rigorous professional 
use. The Four Thirds system makes it possible for a fast lens to be compact and lightweight 
as well.
Focal distance and depth of field of Four Thirds system lenses
When compared to 35-mm cameras, Four Thirds system cameras achieve different effects at 
the same focal distance and aperture.
Focal distance
At the same focal distance of a 35-mm camera, a Four Thirds system camera can achieve a 
focal distance equivalent to twice that of a 35-mm camera. This enables the design of 
compact telephoto lenses. A 14-50 mm Four Thirds system lens, for example, is equivalent to 
a 28-100 mm lens for a 35-mm camera. 
• When the image angle of Four Thirds system lens is converted to that of a 35-mm camera, 
the perspective is the same as that of a 35-mm camera.
Depth of Field
A Four Thirds system camera can achieve a depth of field equivalent to two times deeper 
than that of a 35-mm camera. This enables more light to enter through the aperture. A Four 
Thirds system lens with f2.0 brightness, for example, is equivalent to f4.0 when converted to 
the aperture of a 35-mm camera.
• You can achieve the same amount of background blur as if you were using a 35-mm 
camera.

Notes
• When you attach or remove the body cap and lens from the camera, keep the lens mount on 
the camera pointed downward. This helps prevent dust and other foreign matter from getting 
inside the camera.
• Do not remove the body cap or attach the lens in dusty places.
• Do not point the lens attached to the camera toward the sun. This may cause the camera to 
malfunction or even ignite due to the magnifying effect of sunlight focusing through the lens.
• Be careful not to lose the body cap and rear cap.
• Attach the body cap to the camera to prevent dust from getting inside when no lens is 
attached.
