Reviews Word on the street for the Samsung NX20

The NX20 has a wide range of manual controls plus a Smart Auto function which automatically selects the best shooting mode, while the Smart Range feature captures detail in both the bright and dark areas of the picture.

The NX20 offers a good range of semi- and fully manual exposure modes including the standard quartet of Program, Aperture-priority, Shutter-priority and Manual (PASM) exposure modes seen on DSLRs.

The camera is ruggedly built with some great features, including the articulated AMOLED screen, Wi-Fi connectivity features, GPS, built-in EVF and Full HD video recording.

What People Are Saying Give it to me straight


Plus, when you consider that Samsung's kit lens really isn't very good, you're going to quickly increase your outlay as you buy more optics for the camera.

Better still, the i-Function button can be customised to your own preferences, so you can use it for anything from cycling through the camera's built in Smart Filters to activating the intelligent zoom (i-Zoom).
by TrustedReviews (Jul, 2012)
Advanced users may find the lack of ultra-wide angle, super-telephoto and lenses with a maximum aperture faster than f/2.8 a little limiting.
by TechRadar (Jul, 2012)


The 20.3 megapixel APS-C CMOS megapixel sensor used in the NX20 produces noise-free JPEG images at ISO 100-800, with ISO 1600 also looking very good.
by Photography Blog (Jun, 2012)
At 20.3 million effective pixels, the CMOS sensor found in the Samsung NX20 isn't the highest resolution APS-C sensor currently available, so it will be interesting to see if this compromise results in a gain in quality when shooting at high ISOs.
by TechRadar (Jul, 2012)
Note that the RAW files are massive, weighing in at 37Mb each, which is almost as large as those from the 36 megapixel Nikon D800.
by Photography Blog (Jun, 2012)


It's filled with 614,000 dots, which isn't as sharp as the 921,000-dot displays on some other cameras, but it's still a very good display, with great contrast and color reproduction.
by David-Pierce (Jul, 2012)
It has a 0.68x magnification and offers 100% field of view and the resolution is an impressive 1.44K dots, resulting in a detailed and bright display that should persuade most non-believers to use it.
by Photography Blog (Jun, 2012)
The NX20's 3-inch, 614,000-dot rear LCD screen is very impressive, incorporating AMOLED (Active Matrix Organic Light Emitting Diode) technology that provides a number of key advantages over traditional LCD screens.
by Photography Blog (Jun, 2012)


There's a remote viewfinder app for iOS and Android that connects via an ad-hoc Wi-Fi network to your camera and lets you use your phone as a viewfinder for your camera and even take pictures, control the flash, or set a timer.
by David-Pierce (Jul, 2012)
This is a particularly good model, but many of the same advantages apply to all EVFs: you can see a lot of information on the display, and even review your photos without taking your eye away from the viewfinder.
by David-Pierce (Jul, 2012)
Its EVF is a vast improvement over Samsung's previous efforts, the vari-angle LCD monitor is immensely useful, and overall image quality is excellent.

Image quality

Default settings can result in quite muted colours, so it's well worth playing with colour settings in-camera to improve saturation and contrast.
by TechRadar (Jul, 2012)
Low light AF performance is pretty good for a compact system camera, only hunting in very dark conditions.
by TechRadar (Jul, 2012)
Colors looked great, as do details in the shot — though as with still images, you might run into trouble with dynamic range.
