I read the following on the DxOMark website last night regarding their assessment of the RED Helium 8K sensor:
"RED’s prototype Helium 8K sensor has shattered our previous top DxOMark sensor score. With a dramatic jump to 108, it leaps past the only other sensor to have broken the 100 barrier – RED’s own Epic Dragon prototype (101 points)."
https://www.dxomark.com/Reviews/RED-Helium-8K-DxOMark-Sensor-Score-108-A-new...me-high-score2
"the only other sensor to have broken the 100 barrier" ... really? I seem to recall a certain sensor whose results had been published (leaked?) for a few hours a while back that also broke the 100 barrier. I think the 645Z got an overall score of 101 if I'm not mistaken.
I also remember that we were promised a full fledged review of the Z, but we are still waiting for that. Does someone have any news on a forthcoming DxOMark review of the 645Z, or should we just forget about it?

I know you're looking for a prime, but I must say that you won't find a better lens than the DA 645 28-45mm F4.5 in the current line up if what you want is a 45mm lens. It's tack sharp, it has shake reduction, and it's weather sealed. But I won't lie to you, it's super heavy and very expensive, so it's a big investment in the 645Z system. You won't regret it though if you decide to go down that route. I haven't so far.
I also own the FA 645 45-85mm F4.5. The two lenses can't be compared; it's apples and oranges really.
