The 85mm GM lens is in Stock at BHphoto (Click here).
Diglloyd seems to have spotted another bug:
With both the Sony GM lenses (85/1.4 GM and 24-70/2.8 GM), Sony A7R II does NOT open the lens diaphragm to focus, at least not under reasonably bright to somewhat dim conditions (checked over 3 different days).has no effect on the behavior.
I guess this is something that can be fixed by Sony via firmware upgrade.
DearSusans started his ongoing 85mm GM lens review:
Wide open, there is a modest loss of apparent sharpness due to a very slight loss of contrast. But first it is very slight, then it clears up not only by f:2.0, but already by f:1.6 (the aperture range moves in 1/3 stops). From f:1.7 on down, the lens hardly improves, but its rendering becomes just a tad less warm and more neutral. So, in effect, you have a portrait lens wide open, where many prefer not to show too much detail and sharpness (I happpen to disagree), and lovely, romantic colours, then a lens for close-up and street from f:1.6 to, say, f:4.0, then a landscape lens from f:4.0 onwards.
