Personally I’m not a video shooter and beyond the occasional souvenir clips I pretty much never use video. In fact, after owning my E-M1 for a month, I have yet to test it’s video capabilities. But there are many excellent M4/3 based video camera, mostly from Panasonic and BlackMagic, and looks like the E-M1ii will be a serious 4K camera too.
There are many cine-ready lenses for M4/3, including all the Olympus M.Zuiko MSC premium primes and PRO lenses. We also have several third-party manufacturers offering specialised cine lenses for M4/3 and a new one just joined the ranks. Fzeros is a new Taiwan-based manufacturer and their first release is a M4/3 25mm T/0.95 manual focus cine lens with 11 blade click-less iris and a super-precise 355 degree mechanical focus ring. It should be a bokeh monster.
