+ | The **Olympus E-M10 Mark II** is a mirrorless camera introduced in september 2015; it features a **4/3 sensor** (17.3 x 13.0 mm) capable of 4608 x 3456 pixels, an **OLED electronic viewfinder** with 2.36 Mpixels and a 3.5 inches touch screen. 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/ | ||
+ | |||
+ | The camera, in combination with the **M.ZUIKO 12-42 mm pancake lens** (28-84 mm equiv.), is extremely compact and portable. | ||

===== AEL/AFL and Back Button Focus ===== | ===== AEL/AFL and Back Button Focus ===== | ||
+ | |||
+ | The **normal behavior** for autofocus and automatic exposure is to **press the shutter button halfway**: the camera performs AF/AE and generally keeps the values locked while you keep the button pressed halfway. Then you can **change framing** and **shoot** by pressing the button completely. | ||
+ | |||
+ | This behavior can be changed, for example by **separating the AF and AE functions**. Only one of them will be associate to pressing the **shutter button halfway**, the other will be associated to another button, usually a **Fn key**. In general **the Fn button will be used first** (to activate AF or AE), the other //auto// function will be activated by pressing the shutter button halfway, just before completing the shot. | ||

+ | ===== 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: | ||
