When taking longer sequences in continuous mode, the main problem is how to keep pressed permanently the shutter release button of CA-1. One solution was to use a rubber band around CA-1 (http://www.ricohforum.com/viewtopic.php?f=47&t=2641&start=10), or hold the shutter release button by your own finger... Recently (while testing the future external timer for Ricoh cameras) I realized that the problem above has a very simple solution: Switch your CA-1 on, set the camera to Continuous mode (CONT=ON),
press and hold the CA-1 shutter release button, which starts the
sequence. Next, while still holding the CA-1 shutter release button
pressed, switch the CA-1 off (using its ON-OFF power switch). After
switching CA-1 off, you can now release its shutter release button,
without stopping the sequence. Everything is related to sequences of
pulses the CA-1 sends to the camera, to simulate half-press, full-press
and release of the shutter release button, see If needed, you can stop the sequence (before reaching the 999 shots limit) by half-pressing the camera shutter release button and releasing it, or by switching the CA-1 on again and doing the same with the CA-1 shutter release button. In principle, this should work with any of the recent models, supporting CA-1 (R/CX series, GX and GRD series). Tested with GX100 and R10. [and now also tested with R3 and R4... Guy] Martin |
