<p>It might be playing third-fiddle to Canon and Nikon, but Pentax - now part of Ricoh Imaging - is a venerable name in the field of photography. Its long history means that its DSLRs, like the now-top-spec K-3, can more than hold their own. The company not only has years of experience to draw upon, but an extensive back catalogue of lenses that can rival the market leaders. It isn't shy to innovate, either.</p><p>The K-3 isn't that dip into a larger, full-frame sensor that some had been hoping for, but the model doe introduce the highest resolution we've yet seen from the company. If the 24-megapixel sensor sounds similar to the Sony Alpha A77 or A65 then it's for good reason: it's the very same base sensor. But Pentax has a certain way with its image processing and, typically, we've found the company to get the utmost out of raw hardware. Can the K-3 succeed in continuing this success and does it stand out beyond its Canon and Nikon peers?Do the shake</p><p>The Pentax K-3's new sensor also has another trick up its sleeve: it does away with the low pass filter. This filter is traditionally used to blur the incoming light slightly in an effort to avoid jagged-edges and the effects of moire on the image, where fine detail in the source material lines up with the grid layout on the sensor.</p><p>Instead of the filter, the K-3 applies microscopic shakes to the sensor at the point of exposure to achieve the same result. Pentax calls the hardware option "advanced anti-moire". The primary benefit of this approach is down to choice. Because with it switched off certain subjects will benefit from the absence of the low-pass filter, while others, such as pin-stripe suits with their closely-aligned lines, would fall into issues. Or not, as is the case here, as the option of on or off isn't something any other manufacturer has tackled.Rugged construction</p><p><a href="http://www.pocket-lint.com/review/126781-pentax-k-3-review">Keep reading...</a></p>
