Someone at the office just got a E-M5 Mk2 and I had a look,
The IBIS is AMAZING - it really was jaw dropping, thought my 12-35mm OIS was good, but gee!!
Sounds like Olympus have upped the Bitrates to 50+ so we are back to GH3 realms in terms of quality.
Thinking that IBIS of this quality would really help underwater with DSLR rigs, with slight movements etc (as I think we can all agree, they aren't as stable or balanced as a camcorder rig from gates etc..)
Uncompressed 422 out of the HDMI too... Filming in 4k is great and it really does provide super 1080, but do think more stable footage would be stellar.
Alas he has gone on holiday so I can't even borrow it to do some side by sides
