Hello there,
I have always been impressed with the weather sealing of the 645D, but one weak point is the remote release socket. If this is open when the camera is exposed to moisture, I have had malfunctions occur. Which got me wondering about the wireless remotes, such as the O-RC1. Are they a good solution, since they do not need the opening around the remote release socket to be opened? Do they work from the rear, or do you have to point it at the front? Can they be used with Bulb mode? If so, how? Do you need to hold the button in continuously, or is there a way to lock it, or to have one button press start the exposure and another end it?
All advice gratefully received!
Ed
