QuoteI can't see this being an 'in-camera' codec for some time yet and 3rd party recorders will have to become much more powerful to record to H.265 externally.
Not only has it arrived (1 year later), it has arrived at a consumer level price.

The only thing I don't like about this camera (for the price), is the retarded lens mount that no one cares about. Dear God I wished they had used micro four thirds (since there are a tonne of active adapters for it).
I'm a wedding photographer. I would totally shoot a wedding with this (in favor of my 5DII) for stills. For video, it's a no-brainer.
If those samsung lenses prove to be sharp, it may well be my next camera(s).
With the hybrid AF system, a 28MP crop sensor, it may be the world's best sports camera.
Of course, pro photographers take a long time to get with the program. Mostly because they are wedded to lenses. Samsung may have shot themselves in the foot with their STUPID STUPID STUPID decision to make their own proprietary lenses, and not allow the customer to choose. This could have been a GH4 killer.
By some freak miracle, metabones might decide to come to the party, but I doubt it. They have to justify their choices based on market share.
