Hi Bill, thank you very much for your comprehensive response to my request for ideas: the PXW X70 is a very interesting camera in my price range and one I had been looking at.
On the PRO side the shallow DOF is very impressive as are the optical stabilisation and the handling of low light.
On the CON side (for me!) if buying a conventional camcorder I might miss the three discrete rings which I have on the EX1 and NX5. I have a few doubts about the build quality. Again, Avid Media Composer is not fond of ingesting the various flavours of AVCHD which I have on some cameras but gives me no difficulty when importing .MXF from my EX1 or .MOV from my BMPCC, say.
All that being said I haven’t yet ruled it out.
I would have thought that the GH4’s MFT sensor would be at least as good as this camcorder in low light given its size,- has that not been your experience?
Thanks again for your thoughts.
