Pentax K-3 III & K-3 III Monochrome Firmware Update v2.00

Ricoh has released firmware updates for both the Pentax K-3 III and the K-3 III Monochrome which add new features to both cameras:

  • Type 3 AF.C tracking that uses user-selected AF points
  • Users can now fine-tune AF.C focus sensitivity  
  • USER BOXES allow you to save your best settings and share them via SD cards
  • An improved number of consecutive frames when shooting in crop mode

There are also the usual fixes that improve stability.

In addition, there is a Graduated Neutral Density software package that is currently only available in Japan for an additional fee. “Grad ND shooting takes two images with different exposures and synthesizes them,” according to Ricoh.

The K-3 III firmware is available here, while the separate K-3 III Monochrome firmware is here (see below for installation instructions).

According to Ricoh, the new Type3 AF point tracking uses your selected autofocus points for tracking. This is an addition to the current Type1, which uses both the autofocus and autoexposure sensors to track, and Type2, which uses the autofocus sensor and all autofocus points.

The AF.C focus sensitivity setting allows users to select from a 5-point scale, with 1 being the most stable and 5 being the most sensitive to movement. The default setting is 3, which is the previous conventional tracking setting.

Box settings will allow users to save up to 10 sets of frequently used settings, then export them to an SD card. Saved boxes can then be imported, allowing users to set up new cameras or share your best setups here on PentaxForums!

Ricoh also said that there has been an increase in the number of images captured during continuous crop mode shooting, but did not give any details.  We will update this post if our tests reveal a significant change here.
