Can anyone confirm that the LRT PRO Timer 3 can be used with the Leica SL2 and SL2-S? The Leica store could not confirm that their external shutter release would work with non-Leica cables/shutter release.

It should work. The LRT PRO Timer is highly configurable (release time, AF time etc.). If any other intervalometer can trigger the camera via an analog release cable, the LRT PRO Timer also will.

As soon as I receive the camera I'll test it and let you know definitively. Thanks.

Any update on the compatibility?
