Pentax is carving out a substantial niche for itself by focusing many of its products on the outdoor and adventure market. Today the Ricoh-owned camera maker introduced two new flavors of its top line camera, the Pentax K-5 II and Pentax K-5 IIs. Both cameras feature a rugged body construction that is water-, cold- and dust-resistant, and are built around the same 16MP APS CMOS sensor. The main difference is that the K-5IIs comes without an anti-aliasing filter, making it better suited for commercial and studio photography, while the K-5 II is designed to be taken to places where the photographer may not necessarily have control over lighting.
Pentax K-5 II Key Features:
16MP CMOS sensor
Anti aliasing filter: reduces moiré patterning
ISO range 100-12,800 native, expandable to 80-51,200
3-inch, 921k dot LCD monitor

Viewfinder with 100% field of view

18 digital filters

The Pentax K-5 II's magnesium alloy exterior and highly rigid stainless steel chassis is stur dy and lightweight, with 77 seals to keep out dust and rain. The camera is claimed to offer reliable operation down to 14 degrees F, and has a shutter release with a top shutter speed of 1/8000 second, rated to last up to 100,000 shots.
The glass Pentaprism viewfinder offers a full 100% field of view, with a Natural-Bright Matte II focusing screen for easier manual focusing. The camera has a Shake Reduction mechanism that can compensate for up to three stops worth of shakiness, according to Pentax; helpful features include an electric level function with a vertical level scale, automated compensation for distortion and lateral chromatic aberration when using Pentax's DA, D, FA and FA limited lenses (all of which are available at Adorama). You have a choice of three grid patterns while in live view mode.
The difference between this K-5 II camera and the K-5 IIs version is that the K-5 IIs camera does not come with a built-in anti-aliasing filter.
