Originally posted by Bob 256 It's possible that the battery is marginal and when called on to activate the shutter just can't make it, but it could be a shutter motor issue. Like TwoUptons suggested, make sure the battery is a new and reliable one. Any chance this is a low temperature issue? Low temperatures sap Li batteries like the CR5s and if the battery is marginal, cold will make it worse. Not sure what you mean by "powercycle it"??
I’ll try it again when I get home. It was in the 70s yesterday so it should be fine, and I warmed it up in my hand when it gave me issues.
Powercycle - turn the camera off and on again
