 ====== Olympus E-M10 Mark II ======
+{{ .:olympus:olympus-e-m10-mark-ii.jpg?320|The Olympus E-M10 Mark II}}
 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/off/flash lever). The dials, like the three Fn buttons, can be **freely assigned** among many functions.
 The camera, in combination with the **M.ZUIKO 12-42 mm pancake lens** (28-84 mm equiv.), is extremely compact and portable.

+^ Pros ad Cons  ^^
+| {{:img:pros_icon.png?nolink&36|}}  | Good **viewfinder** with 2.36M-dot, diopter adjustable.\\ Very **compact size**: 120x83x75 mm, 514 g (with the 12-42mm pancake lens).\\ Two **big dials** easily operated by fingers, while keeping the eye into the eyefinder. Can be configured by the user: e.g. use the **rear dial** to choose the shutter speed and the **front dial** to adjust the exposure.  |
+| {{:img:cons_icon.png?nolink&36|}}  | **Saving** or **loading** of **custom camera settings** is not supported by the OM Workspace software.\\ Starting the **playback** requires full activation of the camera (the M.Zuiko pancake lens extends the zoom).\\ The menu to handle the **Mysets** is sub-optimal: saving (overwriting) of the settings can be activated by mistake instead of loading them.\\ Cannot **delete a range** of photos, must select all of them.  |

 ===== Anti-Shock and Silent Shutter =====

 ===== 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.
+The **default behavior** for auto focus and auto exposure is to **press the shutter button halfway**: the camera performs both **AF** and **AE**, keeping the values locked while the button is 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.
+This behaviour can be **separately changed** for the three focusing modes: **S-AF**, **C-AF** an **MF** (single and continous auto focus, manual focus); the relevant menu is **Custom Menu** => **A. AF/MF** => **AEL/AFL**.
 {{.:olympus:menu-af-mf.png?200|AEL/AFL Modes Menu}}
-{{.:olympus:menu-af-mf-mode1.png?200|S-AF Default Mode for AEL Button}}
+The default is **mode1** for all the three focusing modes. **Automatic exposure** and **focus** are **both** performed when the button is pressed **half way** (only the exposure is performed in manual focus, obviously):
+{{.:olympus-e-m10:ael-afl-menu_s-af_mode1.jpg?200|}}
+{{.:olympus-e-m10:ael-afl-menu_c-af_mode1.jpg?200|}}
+{{.:olympus-e-m10:ael-afl-menu_mf_mode1.jpg?200|}}
+If you want **only** the **auto focus** function when the button is pressed **half way**, you can choose **mode2**. The **exposure is not locked**, it changes as you change the framing until you press the button completely:
+{{.:olympus-e-m10:ael-afl-menu_s-af_mode2.jpg?200|}}
+{{.:olympus-e-m10:ael-afl-menu_c-af_mode2.jpg?200|}}
+**In any case** you can have a **button assigned**  to the **AEL/AFL function** (e.g. **Fn1**); so you can always do an **Auto Exposure Locking** regardless the shutter button half way, using the **Fn1** button.
+Finally there is the **mode3**, which substantially is like mode2, but it **inverts** **exposure** with **focus**. Pressing the shutter button half way performs only the **auto exposure**, the focusing is delayed until the full button press. In this case, the **AEL/AFL** button (e.g. **Fn1** in the example above) performs the **Auto Focus Locking**, not the exposure. This is called **Back Button Focus**.

+Beside the **Scene mode** called **Portrait** (selectable when the mode dial is into the **SCN** position), there is also a **Picture mode** named **Portrait**, selectable from the **Super control panel**. According to the article [[https://www.dpreview.com/forums/thread/2955623|E-5 "Natural" and "Portrait" Mode Comparison]] (wich describes the Olympus E-5) "//it reduces contrast by slightly lifting shadow areas, which has the effect of softening the detail very slightly -- but not too much. It also warms the image slightly which improves skin tones by decreasing the red hue//".
+===== 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:
+^  Full F-Stop  ^  E-M10 F-Stop ^ Note  ^
