When we bought the Sony PXW-X70 back in October 2014 part of the deal was an firmware upgrade to 4K, four months later and no sign of the promised software ! Yet the exact same model in its domestic guise the FDR-AX100 came out before the X70 with 4K as part of the deal.
Almost every 4K Sony professional camera to date is unfinished, awaiting software, the PXW-Z100 just got AVCHD last week after a year, PXW-FS7 awaiting FW for the back unit (Pro Res etc) and the PXW-X70 awaiting its 4K upgrade !
This is becoming the norm rather than the exception for Sony. I do think if you are going to sell sequential cameras like “buy part one and get part two free” you need to be as honest as possible with your “part two” dates.
Sonys web site still bangs on about a 4K upgrade “The PXW-X70 is also 4K ready and can handle 4K recordings with a future upgrade.”
Sony Reply…” Hi Philip, we will be confirming the 4K upgrade details by the end of this month. The plan was for the upgrade to be available ‘early 2015′ and the exact detail we will confirm in due course. Apologies if this was not clear in the communications! “
