Pentax DSLRs are known for their innovative, unique qualities like weather sealing; the manufacturer's 2013 advanced enthusiast model, the K-3, has piqued our interest with an anti-aliasing filter that can be turned on and off. Anti aliasing filters prevent patterns, such as the pattern in certain textured clothing, from becoming distorted. However, when the filter isn't needed, it's just another filter for the light to pass through. Cameras without the anti-aliasing filters tend to perform better in low light and capture more fine details than other cameras with similarly sized but filtered sensors. But, until the K-3, you'd need two cameras to have both options. The K-3 allows the user to turn the filter on and off and even adjust the intensity. And while the anti aliasing feature is what first grabbed our interest, the K-3 also has 8.3 fps continuous shooting, which is quite high for the category. The K-3 also has a redesigned autofocus with 27 AF sensors and improved video quality over the K-5. And, the K-3 is still weather sealed. The K-3 looks to be an excellent option among the advanced APS-C DSLRs.
