So its been awhile since RedRock Micro announced their MicroEVF and Zacuto showcased their ideas for the Z-FinderEVF. Since then there have been some changes in specs, information, pricing, etc. The main changes being Zacuto adding mounting options, and Redrock adding a loupe through HDMI support (copycat?). Here are some videos from both manufacturers updating us on EVF info.
