The small Samsung serves only as a pocket camera, an RX 100II is also available too.
And the job as bag camera makes the NX Mini quite outstanding.
Handy, small, yet maintain reasonably good, very good to use. I shoot mostly in aperture priority -A- and select aperture and ISO speed and exposure compensation -if required- like yourself, leave not the camera.
And that is even without first-class dedicated dials in NX Mini. Screen Tap adjust any parameter and trigger. Even an AE lock can be placed on a button. Class!
The image results are up to 800 ISO very good, including up to 1600. Still very usable, from 3200 then only for small prints.
The NX Mini is image quality does not lag behind the RX 100II.
The kit lens 9-27 is very good even at full aperture, shows no edge slope.
Emphasized at the small Samsung it's incredibly good price / performance ratio, because that comes with the camera an extra small flash (supplement to the built-in flash) and Photoshop Lightroom 5 (alone PS Lightroom already has a value of more than 100, -).
The camera's battery is for about 600 shots well and -sensationell - costs than original Samsung gereade times 14, -. If you compare with the price of genuine batteries, Canon, Nikon, Sony and Co. expected the joyful grin about this little Samsung even be wider. Great camera with excellent performance for tiny price.
