Samsung NX200 KIT Compact System Camera - Black 20.3MP,(Inc; 20-50mm Lens & Flash gun) 3.0 inch AMOLED display , 3D Panarama, Full HD, 1080 30P Video,7fps etc

I wanted top IQ in a pocket option without spending a fortune,micro 4/3 lenses are overpriced in my opinion,and the direction of there lenses are not doing it for me.
Samsung have a great expanding lens choice, 16mm,20mm,30mm and soon to be released 55mm f1.8,all pancake lenses,which for me are what small large sensor cameras should be about.
The new sensor is very much better then the older 14.7 sensor and superior to the 4/3 sensor,looking at jpegs and Raw ,i would say the Samsung sensor is about half a stop behind the Sony NEX 16 meg sensor.
The Dynamic range is brilliant,i can bring out shadows with no noise with ease,and the highlights are very well kept in detail,again far superior to 4/3 sensors.
The build of the NX200 is fantasic and the grip makes one handed use really easy as well,screen is OK,but i have seen better and sharper screens,autofocus in good light is fast,not so great in low light,controls are good and in the right place for quick and easy use when out and about.
IQ is much improved over the last gen of NX camera's, the jpegs give great skin tones and colours and can be easily changed in camera,noise reduction seems a lot lighter then the last NX generation which over done it, i would say the new sensor is about 2 stops better hence the ability not to need so much noise reduction,jpegs look very very good from 100-400iso , 800iso and above also very acceptable, you can get a bit more out of the RAW files at higher ISO with Adobe etc.
The single worst thing about the NX200 is the RAW buffer is pathetic, very very slow, hence why i have given 4 and not 5 stars.
Still Jpegs are fine on the NX200 and still respond well to manipulation in Lightroom, shadows and highlights respond well enough and colours can be enhanced nicely,auto white balance is also very good even indoors.
If you want a tiny large sensor camera that can fit in a large pocket with a good choice of dirt cheap, good optical quality pancake lenses,then the NX200 could be your camera.
For zoom lenses i would suggest waiting for the next NX with built in EVF .

I can't give a professional review, but in brief:

Quite small already with the 20-50 kit lens, even more so with 20 or 30mm pancake lenses (like this it will easily fit in many coat pockets). Still larger than most compacts of course, but with a lot lot better controls and lenses.

Good sensor, but I get the impression this isn't the best camera for low-light use. For flash photography I can't comment.

Talking about lenses, there aren't a big range available. The 20 and 30mm pancakes are good, the 20-50mm also seems good. I've heard some of the shorter focal length ones aren't so good. The 50-200mm zoom is moderate, but not great quality at high zoom. It's heavier and much bigger than the camera body, but that shouldn't be surprising.

Fun to use. It has two dials on the body which makes it easy to change the most important settings. I do have a gripe though: manual focus can be done in two ways: zoomed in, or looking at the whole frame. Neither is perfect: the zoom takes the whole screen and makes framing difficult (especially because any touch of the focus ring will activate it), while the whole frame mode isn't always easy to get good focus. I'd prefer just the center of the screen to be zoomed in. Also, forget about the "i-function" thing on the lenses. In practice the dials on the body are always faster and easier to use (if you're holding the camera; tripod use might be a little different).

For the little things like batteries and memory cards I've had no problems. You can get a class 10 16GB card and a second (third party) battery very cheaply, which will certainly keep you going all day.

Summary: I like it and don't regret my purchase. It does seem compromise is necessary to have a highly-functional yet small camera, partly because it's a relatively new market and partly simply because of the size restrictions. Also note that you're not going to see a lot of high-zoom lenses in this category because when you've got a big lens there's less point in worrying about the size of the camera; small interchangable lens cameras are a good form factor but not a universal one.
