I purchased the Samsung NX10 which is mirror-less APS-C

The DC Watch in Japan posted a review about Samsung NX10 mirrorless APS-C camera.

The editor of this review is a Japanes reporter. He purchased the NX10 and the three interchangeable lenses in a famouse electronic shop in Seoul, Korea when NX10 was released in Feb. 2010. The total price was 116,270 Yen including 10% tax.

The review was quite positive about the camera.

The main features are:
* Absolutely slim body
- It was similar to the impact of the Micro Four Thirds LUMIX DMG-G1, but the impact of the slim body of the NX10 was stronger.

- The surface of the body is made of resin, but it felt very strong. The rough surface is also well made, so it felt more elegant after really touching it.

* Fast AF. Cool mirror-less camera
- the AF speed was similar to the DMC-GH1 + LUMIX G VARIO 14-45mm F3.5-5.6 ASPH. MEGA O.I.S or little less. Considering the contrast AF, it’s practical enough. However, it’s not enough to catch fast moving subjects like other Micro Four Third cameras.
