Operability that affects sensibility

Pleasant shutter action

The PENTAX K-3 Mark III features a leaf switch, a mechanism previously used in the PENTAX 645Z and PENTAX K-1. Compared to the tactile switch more commonly used in compact SLR cameras, the leaf switch provides a lighter, smoother shutter action and minimizes the camera shake caused by the shutter-release action. It also helps you by providing effortless hold-down of the shutter-release button during continuous shooting.
The time lag between the shutter release and an image capture has also been reduced, compared to the PENTAX K-3 II, while the camera’s mirror- and shutter-driving mechanisms have also been upgraded. By reducing unwanted mechanical actions such as mirror bounce, it provides crisp, pleasant shutter-release action. You can feel the smooth action and speedy response every time you press the shutter-release button.

Ergonomic design for responsive camera operation

For comfortable shooting and easy carrying, the PENTAX K-3 Mark III’s grip and control-button layout have been optimized to accommodate different hand sizes and finger lengths. Perfected after producing a series of mock-ups and conducting repeated verifications, they let you to concentrate completely on your photo shooting.

More versatile Smart Function

The PENTAX-original Smart Function provides easy, single-action selection of menu items and functions.
Featuring a new Smart Function button, the PENTAX K-3 Mark III now lets you preprogram a maximum of five functions from 22 options, and displays a list of the selected functions in the viewfinder window, so you can select the desired function without removing your eye from the viewfinder. It even lets you select and program the desired values for each function, allowing you to more precisely customize this function to meet your preferences.

Compatibility with classic lenses

You must be aware that each of your classic and cherished lenses creates its own distinctive ambience in captured images. That’s why the PENTAX K-3 Mark III has been designed to accommodate classic lenses. The camera not only saves the aperture value as Exif data when you set a desired aperture using the electronic dial, but also lets you measure the light and capture images at closed-down aperture. It even accommodates the TAv mode.*
It also provides more segmented setting of the lens’s focal length in SR (Shake Reduction) shooting.

*The PENTAX K-3 Mark III allows AE photography at the closed-down aperture for M-series lenses and lenses that previously could be used only in open-aperture shooting.

Manual input of lens focal length

When required to manually input the focal length of a lens for SR operation, the PENTAX K-3 Mark III allows you to select a desired length from the history log, in addition to the preprogrammed ones, to minimize the time and trouble required for manual setting.
