Nikon 1 J3 does not impress the DXO Markers: More 'Boo' than 'Woo' again for Nikon's 1 series.

"Although the new Nikon 1 J3 has been updated over its predecessor with the higher-resolution sensor found in Nikon’s top-of-the-line interchangeable lens model, its overall performance scores haven’t improved over the J2. The camera seems to be hampered by the reduction in overall sensitivity range and most notably scored 2/3 stop lower than the J2 for color depth. Given that cameras such as the Olympus PEN E-PL5 and Pentax K 01 perform significantly better than the J3 despite being priced equivalently or less, the J3 doesn’t seem to provide a good value per dollar for those seeking the best image quality from an interchangeable lens camera. . . . read more

In case you missed something: CES 2013 Digital Cameras roundup at Engadget. (PS @ Engadget: what about Sigma?)

all the cameras of CES 2013

"Samsung also had a mirrorless camera to share, and even though we could have squeezed it into the paragraph up above with Polaroid, the NX300 deserves to stand on its own. The company's latest model packs an APS-C sensor that can snap 20.3-megapixel stills, along with a typical 100-25,600 ISO range and a 3.3-inch AMOLED touchscreen. It also shoots 3D stills when paired with the $500 3D-capable lens. The camera itself (with a 20-50mm kit lens) will set you back a cool $750, so it's clearly a class above the Polaroid -- it's also one of the priciest cameras to debut at CES, which only serves to further validate our claim that this show is targeted at consumers. . . . read more
