Is the X5 a viable video choice these days? Has the IQ and/or CODEC improved any? I really want to replace my current setup with either a z15/gh4 or an x5 variant. The X5R certainly ticks a lot of boxes execpt I'm not a fan of the SSD media (XQD would have been so much nicer) nor the cost considering its overall usefulness to me. This leaves me considering the X5 but I'm not convinced...
