Hi,
The new sensor is quite expensive, so I guess that many readers are not going to be able to buy it.
It has also been suggested that the lenses Hasselblad has are simply not good enough for that sensor, a statement about which I have significant doubt.
Now, contrary to some common belief, you don't need to have a 50k$ sensor to discover it's abilities. The sensor is made by Sony and Sony has a sensor that is very close in pixel size to the IQ3 100. So you can shoot say a Hasselblad V series lens on a Sony A7rII and get a pretty decent estimate of how it would perform on the IQ3 100. Now, the Sony A7rII sensor is not identical in design to the IQ3 100MP, but sensor development is happening in small steps.
I have some shots taken with the A7rII mounted on my HCam Master TSII published here: http://echophoto.dnsalias.net/ekr/Articles/H_CF_Lenses_on_A7rII/
Two of these are shifted stitches, left shift, center, right shift. So these cover a large part of the image circle, I would say those images hold up well. They have relatively mild sharpening, "Scenic" preset in Lightroom 6.
I have also compared a 100/3.5 Planar shot on the A7rII with a 100/3.5 Planar shot on the P45+. Same subject but shot a year apart and from a different angle. That image is here: http://echophoto.dnsalias.net/ekr/Articles/H_CF_Lenses_on_A7rII/P45_comp/SS2.jpg
This image shows a different crop on the A7rII to illustrate that the blinders are not causing colour moiré:
"]]Object not found!
But, monochrome moiré is visible on another window:
I would say that it is clear enough from these images that some Hasselblad lenses hold up to 4.5 micron sensors. Hasselblad H-lenses are probably better performers than the V-lenses in general It may be that Phase One's Schneider lenses are better. Capture One has quite intensive sharpening as default and that may give those lenses a bit of extra "shine".
Some of the Hasselblad H-series lenses are calculated for 60 mm image circle and would have issues with the corners on the IQ3 100MP.
Best regards
