Olympus PEN E-PL2: The Olympus PEN E-PL2, was announced in early January 2011 at the CES.

Olympus SP-510 Ultra Zoom: The Olympus SP-510UZ (Ultra Zoom) is a 7.1-megapixel bridge digital camera introduced by Olympus Corporation in 2006.  It replaced the 6 megapixel SP-500UZ model that was launched in 2005.  It was the last model of the SP-series (Special Performance) that used a 10x optical zoom lens.  It was also the last of the larger-sized 10x optical ultra zoom cameras to be made by Olympus, which had been part of the C-series before the SP-series was produced.  The SP-510UZ model can be traced back to the C-2100 Ultra Zoom, which was launched back in 2000.  The successor model to the SP-510UZ was the SP-550UZ.  It used a longer 18x optical zoom lens.  Today, the newest model in the Ultra Zoom camera line, the SP-590UZ, features a 26x optical zoom lens.  In 2009, Olympus released a compact camera with a 10x optical zoom lens.  However, it does not use the Ultra Zoom name nor is it a part of the SP-series line of cameras.
