The K-7 gets a revised version of the 15.1 million pixel sensor (14.6 million effective pixels) used in the K20D. Four-channel readout allows faster output and video. The K-7 gets a magnesium alloy body, allowing it to become smaller and lighter, while still feeling very well built.
The already good viewfinder in the K20D has been tweaked to offer 100% scene coverage. The K-7 also gains a new, 77 segment metering sensor.
As with the K20D, the body design includes extensive environmental sealing. Pentax has also developed "weather resistant" versions of its kit lenses, to make the most of the body's resilience.
The K-7 becomes the first Pentax DSLR to record movies. There's a mono mic to add sound. Or a socket to allow an external microphone to be used, instead.
To boost low-light AF performance, the K-7 gets an AF-assist illumination lamp. The D-LI90 battery has 1860mAh capacity, meaning 13.4Wh, rather than the D-LI50's 12Wh. The new battery is a completely new shape and is not compatible with older models.
Pentax has considerably refreshed its user interface. There is a revised quick info menu, and the menu interface now breaks the tabs from the K20D down even further so you will not need to scroll down. A battery grip is available for the K-7. It includes control dials, preview lever, AEL, green and AF buttons in addition to the shutter button. The D-BG4 takes one D-LI90 or 6 AA batteries.
The in-camera RAW-conversion tool has been updated and now includes the ability to correct chromatic aberration and distortion, to add shadow adjustment and even output as a TIFF Pentax has also added a multitude of little features, including professional features such as the ability to embed copyright information into the EXIF of all your shots
Composition adjustment allows to fine-tune your composition without moving the camera. Instead the system moves the sensor using the shake reduction system. Very useful for precision work on a tripod. When activated horizon correction automatically corrects for a camera tilt. Again this features uses the shake reduction system to move the sensor.
