Ricoh Imaging has released firmware upgrades for three of its DSLR cameras in preparation for the arrival of a trio of new HD lenses to the K-series. The Pentax K-3, K-S2 and K-S1 will have updates that allow them to get the most out of the forthcoming HD Pentax-D FA 150-450mm f/4.5-5.6ED DC AW and HD Pentax-D FA*70-200mm f/2.8 ED DC AW lenses, while the K-3 and K-S1 additionally get new instructions on how to handle the HD Pentax-DA 18-50mm f/4-5.6 DC WR RE standard zoom.

The new AF point pre-set feature that the HD Pentax-D FA 150-450mm f/4.5-5.6ED DC AW offers, which allows users to access a particular AF point via one of four AF buttons on the lens barrel, is also accommodated in the firmware for the K-3 and K-S1. As the K-S2 was launched after the lens was announced it already has the means to connect with this feature.

Pentax says these firmware updates also bring ‘Improved stability for general performance’. The new firmware for the K-3 is firmware version 1.20, while that for the K-S1 is version 1.10 and that for the K-S2 is version 1.01. Each of these can be downloaded via the Ricoh Imaging software downloads page, where further information can also be found.
