Hasselblad back on tech cameras?

[gigdagefg]

In a recent software upgrade the H4D50 back allows one to check focus at 100% with the press of a button. The rendering is almost immediate (5 seconds or less) and tack sharp. I have demod the Phase IQ backs and its focus mask is excellent-wish Hasselblad had a focus mask----but I can determine sharpness adequately on the H4D50
