I was first advised to do a re-calibration back in May, 2015 when I first reported the "High Contrast/Dynamic Range" issues privately to Rick and Jon. I wasn't experiencing any hot pixels at that time but somehow the calibration was 'sposed to also fix the contrast problem I first reported all that time ago. It didn't. Then after several go arounds with re-calibration and several camera units later due to focus issues on two units and one completely failed unit that just showed static on the screen after boot-up I was advised that the calibration was now permanently secured and quarantined at the factory and I wouldn't need to concern myself with that any further especially with the latest V2 unit that was shipped to me.
The notion that someone is now here in October, 2016 suggesting that I consider trying a re-calibration at this point and that this camera is still having exposure challenges, hot pixel issues and is still on beta firmware almost 18 months later makes me want to tear my hair out!
If the camera didn't have all the other redeeming qualities I believe it has I would have thrown the towel in long ago but I'm keeping the faith and still hanging in there....for now.
I feel like I can almost see the tunnel!
