Hi,
The IQ 250 upscaled to "full frame" 645 would be around 85 MP, keeping the pixel pitch. I don't know which vendors Phase One is working with, but would be feasible for Dalsa to make a 100 MP sensor for Phase.
Personally, I like small pixels, but I also realise that small pixels don't work well with large beam angles, like the ones coming from symmetrical lenses of short focal length.
It may be possible that shallower wells work better, but I guess that shallower wells may give up a bit of DR.
I would guess that one problem with MF is that sensor design is driven by developments where the optical system and sensor are optimised as a whole, like mobile phones.
It may be possible that a vendor like Phase One would be able to designs a sensor with say Dalsa that takes technical cameras into account. But it is a bit complex. Phase One is also a camera maker, and technical cameras is not a dominant piece of the market for Phase.
I guess we have to wait and see to find out.
Personally, I am pretty sure that small pixels are optimal for the DSLR/Mirrorless market. With technical cameras it is a bit different, due to he large and variable beam angles.
I would guess that we may see more complex sensor designs with shallower pixels combined with increased full well capacity, that would solve many of the issues we face today.
Best regards
Erik
One question I keep asking is: if you make a 80 to 100 MP CMOS a sensor based on the technology of the IQ250 this would the pixel pitch get even smaller than the current IQ250? If so then this new Full frame CMOS would have less than desirable performance with tech lens camera especially when movements are needed?
Wouldn't any full frame sensor have to have an even smaller pixel pitch?
