Pentax K5 300x225 Pentax K 5, The Full TestIn September 2006 presenting the K10D digital SLR, Pentax ventured for the first time in the market for digital SLR range of medium to high in comparison and competition with rivals such as Canon EOS 30D and Nikon D200. Four years later, the SLR market for advanced amateur photographers is more competitive than ever and now the new semi-professional camera Pentax K-5 must deal with Canon 7D, Nikon D7000 and the D300S and the Olympus E-5.

At a superficial examination of the Pentax K-5 are being tested seems almost identical to its predecessor, the top range of K-7, but inside we find the differences that count, starting with the 16.3-megapixel CMOS digital sensor, probably the same digital cameras mounted on the Nikon and Sony D7000 A55. This new CMOS sensor made it possible to increase the sensitivity (ISO 100-12800 basic, up to 51,200 full mode, now the highest than any other digital camera's APS-C), reaching the respectable rate of 7 fps burst and capture video in Full HD.

Another notable improvement concerns the autofocus system, long awaited by the users of Pentax cameras and lenses. The Pentax K-5 are an improved version of the system inherited from the model SAFOX IX + 645D medium format launched recently. The new AF system includes a focus on color contrast, a more comprehensive coverage of the AF points and a speed of execution finally able to stand comparison with competitive models.
