In my hands the Ricoh remote pressed half-down does not hold focus (blue square or zoomed) with the SX10-IS with the latest releases of either CHDK or SDM*. This issue was reported 2 years ago in this thread:
http://chdk.setepontos.com/index.php?PHPSESSID=84795381a5c1ff6d3a9c1e2a025558df&\topic=3953.msg37131#msg37131*SDM in Stereo mode
does show the desired behavior, but not in any of its _FAST modes.
I would appreciate reports of success with the CA-1 /SX10-IS combination since it might be a problem either with my copy of the CA-1 or with my
"body English" during button actuation.
Thanks!
