Have one we still use with an S1H at work and still pumps out a really nice image in VLOG. Being able to record internal 10bit on cheap SD cards was definitely it's advantage, as well as RAW/6k over HDMI.
However, while light/small, it's body was cheap. It had a POS LCD monitor that was impossible to see outside and/or pull focus and the side handle was notorious for falling off.
In the end, the c300/c200/FS7/FS5 just was better out of the box for a run and gun camera, so I understand why eva1 fell into anonymity. Would love to see a new version with L-mount as it did have promise.
