In 2013, Nikon's interchangeable-lens camera lineup will grow and shrink at the same time. The company announced two new additions to its Nikon 1 series and two new Nikon 1 lenses Monday at CES 2013, including its smallest mirrorless interchangeable-lens camera to date.

The Nikon 1 J series (above and below) was already pretty small, but the new Nikon 1 S1 has an even smaller body than Nikon's previous interchangeable-lens cameras. The first model in the S series shares the same 10-megapixel, 1-inch-type CMOS sensor as last year's Nikon 1 J2.

Nikon is touting the camera's improved autofocus speeds and 15fps burst-shooting mode at full resolution, which are both new features enabled by the camera's new Expeed 3A processor.

Sharing the same new image processor is the Nikon 1 J3 (below), which also adds a newly designed 14-megapixel 1-inch-type sensor, a 15fps continuous-shooting mode with continuous autofocus enabled, a faster contrast-/phase-detection autofocus system, and a higher-resolution (920,000-dot) LCD screen to its bag of tricks. The Nikon 1 J3 is also the first Nikon 1 J series camera with a physical mode dial.

Both new cameras will offer manual exposure controls for still images and shoot 1080i video at 60fps and 1080p video at 30fps, and they both offer pop-up flashes. Though neither camera has native Wi-Fi sharing capabilities, both are compatible with Nikon's separately sold WU-1b Wi-Fi module (below).

The Nikon 1 S1 is slated for February release at £479.99/$500 as a kit with a 11mm-27.5mm lens, while the Nikon 1 J3 will sell for £579.99/$600 as a kit with a 10-30mm lens. The Nikon 1 series has a focal-length multiplier of 2.7X.

The new Nikon 1 series lenses will take care of both the extreme wide-angle end and the extreme telephoto end. The stabilized 6.7mm to 13mm/F3.5-5.6 lens is a tiny, retractable lens with an 100-degree field of view at the wide-angle end, and it will be priced at $459.99/$500. A new compact stabilized 10mm to 100mm telephoto zoom lens (F4-5.6) will be priced at £479.99/$550.

Rounding out the company's CES announcements is a new Wi-Fi- and GPS-enabled point-and-shoot, the Nikon Coolpix S6500, which has a 12X-optical-zoom lens and a 16-megapixel CMOS sensor – and is available in some shockingly bright colours.
