Someone on Dpreview forums mentioned a curious feature that I've never seen mentioned anywhere else - apparently you can push a button during filming and field of view will zoom in 2X or so , and you can toggle this function . Is this real? How is the quality of zoomed in footage ? Can someone confirm this works? A video of results would be amazing ! This could totally push me over the edge toward an Olympus as I do a lot of casual filming with primes . Another question - how easy is it to change exposure parameters, Aperture/shutter speed/ISO during filming ? Are they assigned to wheels ? Thanks! !
