Now its official. Nikon has formally announced the two new compact cameras leaked at the end of last week by a German magazine, the s1100pj and s5100.

Both are additions to its Coolpix range, but they differ radically. The s5100 is a 12.2-megapixel camera with lens-shift type vibration reduction, enhanced motion detection, and a new flash control system, each purportedly improving its night time performance, as well as day.

It also features an improved version of the EXPEED C2 processing system, ramping up the response time to capture fast moving objects with more clarity. And it can shoot 720p HD video with a dedicated button.

Coming in black and blue, the s5100 is yet to have a price ticket slapped on it. Release date is also to be confirmed, but Pocket-lint expects it to come out around mid September.

The s1100pj is a different kettle of fish. As an update to the s1000pj, it too features an built-in projector, designed for sharing pictures and video with your friends or family on a nearby wall.

However, at 14 lumen, this model is 40 per cent brighter than its predecessor, allowing for better images in daylight conditions. It can also be hooked up to a PC or Mac in order to share presentations, pics and video you may have stored on there.

The camera part itself features a 14.1-megapixel sensor, 5x zoom NIKKOR lens, and 3-inch extra high resolution (460K-dot) touch-screen LCD monitor. It can also add picture editing effects directly, including Fisheye effect, selective colour highlighting on an otherwise monochrome picture, and background softening. And there are built-in animations, a paint mode, and the ability to add music files to your slide shows.

Costing £349.99 (414 euros), the s1100pj will be in stores on 16 September.
