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 lenses
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 length 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 length and aperture.
Focal length
At the same focal length of a 35-mm camera, a Four Thirds system camera can achieve a 
focal length 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. 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.
