Pentax K-7 Viewfinder

The Pentax K7's viewfinder is an optical, eye-level through-the-lens type, with the LCD monitor also able to display an image preview, in Live View mode.

Pentax says the K-7's optical viewfinder provides a coverage of about 100% and a magnification of approximately 0.92x. The K-7's dioptric correction adjustment (for eyeglass wearers) has a range from -2.5 to +1.5 diopter. The eyepoint is unspecified. The Pentax K-7's viewfinder is a pentaprism design, which is more costly but brighter than pentamirror implementations. The focusing screen is interchangeable.

The Pentax K-7's viewfinder readouts do a very good job of communicating camera status and exposure settings, showing most of the usual info such as AF points, flash status, focus mode, shutter speed, aperture, focus confirmation, ISO sensitivity, EV compensation, anti-shake status, etc. New for the Pentax K-7 versus the K20D is a multiple exposure icon, display of the metering mode, and an indication when the focus point is being adjusted. The information layout is also slightly different. See the diagram (courtesy of Pentax) below for the complete list.
