KATEN (summer sky): a new special-edition Custom Image mode

In a new approach to SLR photography, PENTAX will release a series of new special-edition Custom Images, designed to create subject- or scene-specific finishing touches in combination with specific PENTAX Limited-series lenses — lenses popular for their distinctive image rendition. As a lens is mounted, the camera automatically detects compatibility with the firmware. Once compatibility is confirmed, the user can then select special-edition Custom Images.

The new special-edition Custom Images cover the seasons: spring, summer, autumn and winter. The Custom Image mode specially designed for each season will be available in combination with specific Limited-series lenses. PENTAX will release four season-specific Custom Image modes over the year.

The first season-specific Custom Image mode is KATEN (summer sky). This mode is designed to emphasize the rich blues of summer skies and depict the fine details of dazzling white clouds.

Compatible lenses:
HD PENTAX-D FA 21mmF2.4ED Limited DC WR
HD PENTAX-DA 15mmF4ED AL Limited

Function Expand Information (Version 1.30)

1. Addition of electronic LV shutter release

In addition to the standard focal-plane shutter release, LV electronic shutter release has been added for shutter release operation during Live-View shooting. Unlike mechanical focal-plane shutter release, it generates very little camera shake. This makes it ideal for macro photography of subjects such as flowers.

2. Addition of 1:1 Crop size setting

In addition to the original AUTO, FF and APS-C settings, a 1:1 format has been added as a cropping size option. Since the PENTAX K-1’s viewfinder also provides a 1:1-format cropping frame, this helps in composing the image more precisely.


Note: All viewfinder indications are displayed simultaneously for explanatory purposes.

3. Addition of two-mode setting to the AA filter simulator bracketing

In addition to the original three-frames bracketing (OFF, TYPE1 and TYPE2), a two-frames bracketing (OFF and TYPE2) option has been added to the camera’s AA (anti-aliasing) filter simulator bracketing.

4. Cancellation of the Smart Function’s bracketing mode

You can quickly cancel bracketing operations by turning the Function Dial to the BKT (bracketing) position, then shifting the bracketing value to “0” (zero) using the Setting Dial. This eliminates the need to recall the menu screen when you want the same effect.
