The NX10’s performance is good, but . In single shot mode it has a shot-to-shot time of 1.2 seconds, while in continuous shooting mode it can maintain a shooting speed of 2.5 frames a second for about 15 shots with a standard class- 6 SD card, or up to 28 shots with a faster class 10 card. It also has a burst mode which can shoot at 30fps but only at a resolution of 1.4 megapixels.
The NX10, like its rival s from Olympus and Panasonic, uses a contrast detection autofocus system, but it is a particularly good one. It has several modes, with 15-zone multi-point or single selectable point. It focuses very quickly and accurately in good light, with performance comparable to a standard DSLR, and is also pretty good in low light, performing approximately as well as the more expensive Panasonic G2 in similar circumstances. It has an AF assist lamp, but the effective range is only about two metres.
Where the NX10 really scores is its overall image quality, which is absolutely superb. The standard zoom kit lens is particularly good, with flawless edge-to-edge sharpness and no trace of chromatic aberration. The 30mm pancake lens is even better, and even the relatively cheap 50-200mm telephoto zoom produces good results, with no image distortion even at maximum zoom. Shooting in Raw mode and converting the images using either the supplied software or Adobe DNG converter produces a level of detail comparable to a good full-sized DSLR of similar resolution. Colour rendition is excellent, and dynamic range is also better than average. Automatic metering is very reliable, and copes well with unusual lighting.
Image noise control is also very good, producing reliably noise-free images at 400 ISO and usable images at 800 ISO in quite low light, although performance at 1600 ISO leaves something to be desired. It’s not going to convince anyone to trade in their EOS 7D just yet, but for a sub-£500 camera it produces excellent results. As for the crucial question of whether or not it produces better image quality than a comparable Four-Thirds camera, I would have to say that yes it does. The margin isn’t wide, but detail, colour depth and dynamic range are visibly superior.
In the NX10 Samsung has achieved something remarkable, a real alternative to a full-sized APS-C DSLR with all the features, performance and picture quality in a lightweight and compact package smaller than some super-zoom cameras. For a surprisingly low the price the NX10 is a great little camera, and a very serious competitor to the Micro Four Thirds systems.
