I would propably go for the BM Ursa Mini right now coupled with some nice glass. Im also trying to get excited about the Raven, but without seeing what it can really do in the field, I remain sceptic.
Awesome, thanks Guy! Very good points.
In the price range you stated, I also think the GH4 would be the best bet. I have shot with one for about 8 months now and I have to say I am pretty happy with it. The battery definitely performs 3+ hours easily.
Any ideas guys? Thanks!
