I asked this on another forum but haven't got an answer yet, so :- Is the tripod socket on the e-pl3 a standard 1/4" - 20? I've RTFM (full PDF version) and it's not in there, searched here, and also Googled without luck. The reason I ask, is that in my Google searches various products, e.g. Joby Gorillapod, that say they are compatible with e-pl3, come with a "standard" 1/4"-20, but also a 3/8" adapter, and I was not sure if the adapter is needed for the e-pl3, hence the socket is 3/8"? Real reason for asking is that I'm considering tapping one of my hiking poles to act as a sort of monopod for when we are out walking - I'll have it with me anyway, so why not get it to multi-task, and should be better than purely handheld - so, need to know which bolt size to buy.
