A feature that distinguishes this camera from other mirrorless ones, is the presence of **two adjustment dials** (in addition to the one which selects the mode and the on/ | ||

+ | ===== Quick sleep problem in viewfinder mode ===== | ||
+ | |||
+ | In **live view** mode the camera will show the scene in the viewfinder (when the eye is near the viewfinder) and into the monitor (when the camera is moved away from the eye). Pressing the OK button, the **super control panel** is superimposed over the scene. | ||
+ | |||
+ | Pressing the //display switching// button on the right side of the viewfiner, you activate the **viewfinder** mode: puttin the eye into the viewfinder you can see the scene, moving it away the super control panel is shown into the monitor. With the default settings the super control panel is hidden after just 3 seconds and the camera will enter immediately into the **sleep mode**. This is the **Quick Sleep Mode**. | ||
+ | |||
+ | This setting can be changed from the **Custom menu** => K Utility => **Quick Sleep Mode: Off**. | ||

+ | ===== F-Stop Values ===== | ||
+ | |||
+ | Traditionally the **f-stop scale** is composed of values which distantiate each other by halving the light that is allowed to come in. A value of **f/1.0** means that the lens aperture (the hole diameter) is equal to the focal lenght. Each following stop value is obtained by multiplying the previous one by **the square root of 2**. So the value **f/1.4** means that the aperture is obtained by dividing the focal lenght by 1.4, and so on with **f/2.0**, **f/2.8**, **f/4.0**, **f/5.7**, ... The minimum aperture is usually obtained dividing the focal lenght by 16 or 22, thus the **f/16** or **f/22**. | ||
+ | |||
+ | The Olympus E-M10 have aprture stops at 1/3 of each full stop values: | ||
