Olympus XA models - strange discovery
The tripod hole on an XA and XA 2 (and I suppose the others too, but I only own these two types) is right next to the battery hatch. I've just discovered, by one of those odd chances, that if you screw a tripod on too tight, the camera won't work - the battery life indicator doesn't respond. Slackening the tripod ever so slghltly fixes the problem. Strange, eh?
