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.
