Pentax K110D is equipped with the SAFOX VIII autofocus system that feature 11 sensor points with nine cross-type sensors to automatically focus on the subject with precision even when it is positioned off center. The in-focus sensor point is automatically superimposed in red in the viewfinder for at a glance confirmation. This high precision AF system offers two AF modes: the conventional single AF, as well as the continuous AF that maintains focus on the moving subject as long as you pressed halfway down the shutter release button.

It features a lightweight penta-mirror viewfinder that combines Pentax-original finder optics with a Natural-Bright-Matte II focusing screen to deliver bright, clear subject images with 0.85x magnification and a 96 percent field of view. It has a large 2.5-inch color LCD monitor on its back panel. The wide-view design allows the user to check the monitor image over 140 degrees vertically and horizontally. It has a total of approximately 210,000 pixels resolution. It also offers digital zooming of playback images up to 12 times for easy confirmation of the images focusing status and details. Its large monitor size allows for large letters, digits, as well as icons on the menu screens to facilitate menu confirmation as well as camera operations.

The Pentax K110D also features the Auto Picture Mode that automatically selects one of the four picture modes that includes Portrait, Landscape, and Macro by means of calculating various photographic factors to guarantee optimum results. The Auto Sensitivity control function automatically sets the optimum standard output sensitivity up to 3,200 which is the highest automatic setting in its class.

It is equipped with a large, high performance 23.5mm x 15.7mm CCD as its image sensor that assures the reproduction of the desired photographic intention. Through the combination of 6.1 effective megapixels with a high performance imaging engine as well as advanced image processing technologies, the K110D can produce beautiful true to life images that are rich in gradation.

The standard software package of K100D consists of the Pentax Photo laboratory 3 that features the reliable Silkypix image processing engine for RAW data processing; and the Pentax Photo Browser 3 that offers faster data processing speed and it can also convert RAW images to the DNG format.

The Pentax Limited Lens series is designed for best image reproduction by combining a series of mechanical and numerical evaluations with human assessment of test shot samples. This lens is equipped with a hybrid aspherical lens in its eighth optical element to effectively compensate for a variety of aberrations that causes adverse effects on overall image quality. It also features a floating mechanism that is designed to adjust the degree of aberration compensation in relation to the focusing distance.
