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.

The Olympus E-M10 Mark II has two shutter modes called Anti-Shock and Silent. The following picture shows the Anti-Shock/Silent page of the Advanced shooting options menu:
To fully understand the meaning of these modes, you need to be familiar with some concepts.

Once you understand the concepts above, you can understand the Olympus E-M10 settings.
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.
|AEL||Auto Exposure Locking: Press the assigned button once to lock the exposure and display AEL on the monitor. Press the button again to cancel the lock.|
|AFL||Auto Focus Locking.|
|BKT||Bracketing: General technique of taking several shots of the same subject using different camera settings.|
|C-AF||Continuous Auto Focus: The camera repeats focusing while the shutter button remains pressed halfway.|
|EFCS||Electronic Front-Curtain Shutter: also known as Electronic First Shutter Curtain (EFSC). It is a feature to eliminate camera shake originating from the shutter mechanism.|
|ESP||Electro-selective pattern: Digital ESP-metering measures the brightness of the center of the subject and the surrounding area separately.|
|EV||Exposure Value is a number that represents a combination of a camera's shutter speed and f-number. A difference of 1 EV corresponds to a standard power-of-2 exposure step (one stop).|
|EVF||Electronic Viewfinder: The image captured by the lens is projected electronically onto a miniature display.|
|HDR||High Dynamic Range: technique used to reproduce a greater dynamic range of luminosity, see High-dynamic-range imaging.|
|HP||Home Position for Auto Focus Area. You can associate the Home action to a function key, then set the default AF area using the Menu ⇒ Custom menu ⇒ AF/MF ⇒ Set Home.|
|LV||Live View: A mode which allows to view the photographic sensor output in almost realtime on the camera's LCD screen.|
|Live Control||Panel to control shooting options, generally activated by the OK and INFO buttons. It is a simplified version compared to the Super Control Panel.|
|Live Guide||Generally activated by the OK and INFO buttons: make it easy to access a variety of advanced photographic techniques.|
|MF||Manual Focus: Manually focus on any position by operating the focus ring on the lens.|
|ND||Neutral Denisty filter: stops light reaching the camera sensor, allowing a higher aperture and/or a longer exposure time.|
|RC mode||Remote Control Mode for external flash units.|
|S-AF||Single Auto Focus: The camera focuses once when the shutter button is pressed halfway.|
|Scene Menu||Activated with OK and INFO buttons, it is a special control panel for ART e SCN modes.|
|SCP||Super Control Panel: Activated on the monitor or into the viewfinder with the OK button, allows you to set the shooting options.|
|S-OVF||Simulate an Optical Viewfinder: Viewfinder display similar to an optical viewfinder.|
|WB||White Balance: Is used to adjust colors to match the color of the light source so that white objects appear white.|
|L, M, S||Large, Middle, Small: Presets for image size in pixels. From 4608×3456 to 640×480.|
|SF, F, N, B||Super Fine, Fine, Normal, Basic: JPEG compression rate, from about 1/2.7 to 1/12.|
|Portrait||According to manual, it produces beautiful skin tones.|
|e-Portrait||The manual says about this mode that it produces smooth skin textures.|
