The NX10 has an electronic LCD viewfinder which is also exceptionally sharp, with a resolution of 920,000 dots. It replicates the display on the monitor, and a proximity sensor mounted just below the eyepiece automatically switches the display from the monitor to the viewfinder when the camera is held up to the eye. Despite its huge resolution the viewfinder display isn't quite as clear as the monitor, and the individual dots are visible. It's not really sharp enough for manual focusing, and it has no magnification to check focus, surely an easy feature to implement on and EVF. Compared to the flawless field-sequential display viewfinder of the Panasonic G2 it does look a bit weak. The refresh rate isn't as fast as the monitor, and it doesn't handle high-contrast scenes as well either, burning out highlights and losing details in shadow areas. The eyepiece has dioptric adjustment to compensate spectacle wearers, but the adjustment dial is fiddly and difficult to set accurately.
As is usually the case with the first model of an entirely new line of cameras, the NX10 is better equipped with useful features than most entry-level models, and is roughly on a par with a mid-range DSLR. One of the most useful features is the Picture Wizard function, which is more or less identical to Canon's My Colours features, found on nearly all of that company's cameras. Operated by a dedicated button it provides a range of tone pre-sets, each of which can be individually customised with contrast, saturation, sharpness and tone. Similarly the white balance pre-sets can be adjusted using a 2D colour temperature chart, and it also has both manual and dial-in colour temperature settings.
Other useful additions include an adjustable self-timer with a delay from two to 30 seconds, although there is no interval timer or ability to take multiple timer shots. The camera also has several auto-bracketing options, including fully adjustable exposure and white balance bracketing, and also Picture Wizard bracketing, which can take three pictures using different tone presets. Thanks to the superb monitor the visual interface for all of these options is extremely clear, with a combination of menu and graphical control interfaces. There is also an on-screen function menu for the most common shooting options, however it would have been nice if this too could be customised.
The NX10 has the obligatory HD video recording mode, but it is not one of its best features. It records in MP4 format at a maximum resolution of 1280 x 720 at 30 fps with mono audio. There are a number of menu options in video mode including Picture Wizard, exposure, white balance, metering and AF options, and audio options including wind cut and fader, but it has to be said that the audio and video quality are not brilliant, and it does suffer badly from the notorious CMOS “Jello Effect”, in which the video image wobbles if the camera is panned quickly.
