It seems that Sony released an MF 33x44mm image size Cmos sensor for use on MF cameras, that will be shared among most MF makers. It also seems that this sensor has been "tuned" to retain the characteristics that MF users have been used at (Clarity, absence of colour shifts, colour accuracy)… It also seems that this sensor was specially designed for use with MF cameras and that its High Iso performance is restricted a bit lower with respect to current Cmos sensors used with DSLRs…
It is interesting that Sony didn't use an existing FF sensor and multiplied its size, but instead, they designed a completely new sensor for the task, which leads to the conclusion that special care has been given on this for the ultra demanding MF market.
I wonder, wouldn't it make sense if they crop it down to 30Mp-24x36mm in size and use it on FF DSLRs too? It seems that (other than ultra high Iso) this is the best Cmos sensor ever made… if only a bit costly. Would such an FF camera damage the MF market? …would it be a threat for Leica S and for Hasselblad H5D? Would people prefer it from the current solutions they have?
