The 250 for a tech camera, may not be the best choice. From all the testing, that DT did, it's clear that if you use a wide angle setup, then you will most likely get some compromised color shifts. DT even went back and revised the usable image circles for the 250 with the 32mm an 40mm, and the revisions are interesting @ 70mm for the 32Rod (90mm total IC) and 80mm for the 40mm R0d (90mm total IC).
To me at the cost point of any of these lenses, that a lot to be not able to use that much of the image circle.
If you also go back and look at the test files, in detail you can see for sure that the even though the shadow recovery next to amazing compared to the 260, the amount of saturation/color fall is just as amazing. I totally missed this when I reviewed the files, until Torger posted his results.
The big question to me, is can a CMOS chip be designed that give all the benefits shown in the Sony 50MP CMOS that won't have the issues shown when shifting which appear to be around the microlenses and design of the chip.
As a tech camera shooter who uses wides 85% of the time, the color issue on top of the 1x3 crop of the sensor really make the 250 a non player. If Phase One can design a new algorithm to resolve some of the extreme color/sat loss which may in fact be possible, then the 250 may be a possible solution, however not at the current prices being given for upgrades but that's another story completely.
If the color issues show up in a outdoor scene, well that really yet to get tested, but I feel that on a blue sky (solid) or with few clouds, they very well create a blue that will not come together due to the loss of sat and hue shifts. I wonder too how these same issues would effect a typical green hillside, as the green color seems to be by far the most effected.
