ProVideoCoalition has a review of the new Panasonic HPX-170. Think of it as an HVX-200 without the tape drive, and with some improved capabilities. It seems like many of the controls and interface options have been refined, and some of the imaging features have been enhanced.
If you weren’t previously considering an HVX-200, this probably isn’t of interest to you. Interestingly, it looks to be hitting the street for almost exactly the same price as the HVX-200 – right around $5200. If you were looking for an HVX though, you might enjoy the slimmer form factor, HD-SDI outputs and revised feature set.
