Seems the company is even working on a 12mm f2.8, to be released this summer.

Check the comments below the article.

Isn't there an intervalometer built in? What a shame, if not....

Cant wait to clip a DL24-85 to my belt. CLS compatilble hotshoe, 1:1 macro, fast lens etc etc.... Perfect compact supplement to the FF Nikon.....

Thanks, but darn.... Would have been nice, considering the poor battery life.

Can the G5 X keep shooting, while being charged from the USB? Would be nifty....

Fully articulating screen, hotshoe, cablerelease/intervalometer socket and EVF.... Just sad they didnt put a decent timelapse app into it ;-)

Nope, but a kit from Lensmate takes care of that.
