I need to pull down the 60mm tests, as that is a lens I use a lot, and I can't figure out why it did not work as well as it does on the 80MP tests, since it's a back with similar pixel pitch.
When I look at the the LCC's for the 250 on the 40mm, they look good to and don't show excessive color cast, and but the room being shot is a pretty big challenge, with all the various lighting.
I agree the 260 shots (at least with the 32mm) appear to be excessively noisy, especially on the shifts and as Doug mentioned there was no Center filter being used and I am pretty sure that would have helped to clean some of the shifted noise up. Overall the details from the 32mm are impressive to me. If you look at the center shot only of the 260, the noise is not as bad as it is on the shifts. It's not up to par with the 250 in the shadows, but not sure the 260 will ever get there.
Torger, your shot from raw therapy is most interesting. I am very surprised to see that much noise at only a 6 second shot at iso 50. I thought the dark frame would remove most of this, as that is why I always felt it was used by Phase One. The long exposures I have taken with the P45+ and developed in Capture One don't show anywhere near this much noise. When I opened the 260 shots, Capture One sets the what it feels is the correct noise reduction/sharpening for the raw image based on the back. Even with the defaults on, there are a lot stuck blue pixels that show up in most of the shadows and even if you take the "single pixel noise" slider all the way to 100%, not all of them are removed. I am going to setup my 260 this evening and take a few longer exposures and see what I get in the deeper shadow areas.
I guess the denser pixel size of the 250 creates less aliasing? The 250 is pretty much clear of it.
I am pulling down the 80MP tests later this morning to see how well that back did in the shadows also.
Long term, I am wondering who will make a full frame CMOS chip and when? No doubt to me that Sony has CMOS figured out, but this was clear 2 years ago with the early testing of the D800. I know that Sony has a patent on a 54MP chip for the 35mm format, but that is most figure a year away from production and even Sony has stated it will not be a inexpensive chip/camera solution. I am sure Dalsa is working on a CMOS solution, but it will be their first (at least in this market) that I am aware of and I have to wonder if it will have the same DR as the Sony designs. I wonder if Phase One can get to a full frame CMOS in a year, and if so what the size/MP rating of the chip will be.
