Ricoh Imaging Updates PENTAX K1 Firmware to Version 1.1
See my Pentax K1 wish list at B&H Photo.
Pentax K1 firmware version 1.1 information page.
Changes to V1.10
• Corresponded to IMAGE Transmitter 2 (Version2.2.0)
• Correspond to PENTAX Tethered Capture Plug-in for Adobe® • Photoshop® Lightroom®(Simple Version)(Version1.1.0)
• Improved stability for general performance.
Pentax has instructions online at the above link. The update process is fast and easy (far better than the kludgy procedures of Sony and Olympus, which require tethering the camera to a computer).
The upgrade was fast and problem free for the K1 I have on hand.
