“Somebody” :) just told me that Olympus will release a new E-M1 II firmware update within two weeks. If anyone can confirm this and share more details about the possible improvements drop me a message at email@example.com. Thanks!
A second source told me this:
Major E-M1 Mark II firmware upgrade that will add some video functions (probably flat profile, unfortunately no 120fps FHD) and expand AF work to -5 or -6 EV (I don’t remember, I think it’s -6 like the E-M1x) with the f/1.2 lenses.
