It does not lack microlenses. It's the same sensor across P65+, IQ160, Credo 60, Hassy 60 MP backs, the Dalsa FTF-9168C (https://www.teledynedalsa.com/imaging/products/sensors/area-scan/FTF9168C/), from the product sheet: "Micro lenses with wide angular response". However the microlenses are of a newer kind and not as "destructive" as they were on Kodak chips.Anyone know if the Leaf Credo 60 uses micro lenses? It is advertised as ideal for technical cameras and I've heard it said among photographers that Leaf Credo is well-suited for such use. Just wondering why, and lack of micro-lenses seems a possible reason. Thanks.
Gladly.doug:
could you point out the differences between a Credo and a Phase?
Bigger issues is the basic design limitation of CCD, namely LiveView. It's been pretty much shown that CCD can work with LiveView albeit with severe limitations. These limitations make it just not very practical to use outdoors at least in my experience. One test with a CMOS back and it's Liveview will put a nail in that thought process.So from what Torger says, the hope is for CCD to live long enough to see BSI. Interesting.
Thanks, Paul, for your response. I've looked at online and greatly admire your work. Based on what you say, if I understand correctly, you were able to shift a 28mm lens (presumably Rodenstock retrofocus) on the Sony chip and get good results. That's, roughly, what, 22mm field of view (in 35mm equivalents)? That's not to bad. Shifting aside, in your view does the CMOS chip (presumably in the IQ250 or Credo 50) provide the same color differentiation as the IQ260? (Some have said the CMOS CFA is noticeably weak to accomplish high ISO, but I'm not sure all agree.) Also your concern over full-frame CMOS is the same one I had explained to me at a camera tech show I visited, though I suppose lenses could be adjusted (made more retro) for those who are willing to pay.The actual color loss on the 50MP Sony sensor due to Crosstalk IMO is minimal up to about 12mm of shift. I was very surprised to see this in testing I did. The amount of color/sat loss before the LCC is quite a bit, but C1 did an AMAZING job of getting it back within reason. In fact with the testing I did with the 40mm Rodie, C1 actually corrected the shifts on the 50MP back better than it does on my 260. And I did test this on a pure blue sky with a 28mm, 40mm and 60mm. The 50mp was easier to clean up on the shifts.
If and when a full frame CMOS back comes from Phase, I have concerns for I feel if they make it a great pixel pitch than the current 60MP backs, then tech camera use will not work, at least with current lenses from Rodenstock and Schenider.

Hi, actually all three Credo 50, IQ150 and IQ250 share the same Sony chip that the Hasselblad 50c and 645z use.Thanks, Paul. In your most recent post you mention an IQ150 in your earlier post you mention the Sony chip; so was "150" a typo and did you mean "IQ250"? Thanks again.
