PENTAX K-3 Mark III (Beta, 1.40)

In addition to adding Astro Tracer Type3, overall operational stability has been improved. By applying, the contents of version 1.31 released on the same day (including the new custom image “SATOBI”) will also be updated.

Astro Tracer Type3 is a mode that realizes an Astro Tracer without using GPS or electronic compass information. It is said that astronomical tracking will be performed from the movement of stars in the preliminary shooting performed before shooting, so there is no need to wait for GPS positioning or precision calibration, and it is possible to shoot even in places affected by magnetism. It is recommended to use O-GPS1 for starscape photography using a wide-angle lens.

A new custom image “SATOBI” has been added and overall operational stability has been improved.

The new custom image “SATOBI” is the opposite of “MIYABI”, which is suitable for expressing colorful landscapes freshly, so it is named Satobi, which is a synonym for Ya. Aiming for a texture similar to that of color photographs from the 1960s to the 1970s, it was developed to reproduce a universal image that makes people feel “nostalgic” in all countries. (via
