Have had some time now to test out a few of the Michael Bass products for the Leica DMR unit and a few of them are ready for consumption! Check out his wired cable release, extension for release, intervalometer, and AC adapter. You can see these products here. The Tekkeon and Quantum Turbo Battery cables are still in testing, but as soon as they’re ready to go, you will see announcements here, on Michael’s website and at the Leica forum.
Below are photos of the currently available accessories, one of my Leica DMR testing out the Tekkeon kit with Leica Intervalometer, and my two R8+DMR units.
