On another thread on Getdpi, tjv is testing a CMOS back on a Techno with a Rodie 55, and his prelim results suggest that 12 and 15mm is quite workable. He hasn't yet posted crops, but will. Due to the back's fabrication, it shifts better along its long side, but results are just coming in. Hope its ok to mention this.Void ain't no troll. He is a very intelligent person who has taken a ton of time to post his findings. I find it sad that some people would such as being a troll.
Every person can make choices and the information he has provided will make it easier for someone to see the differences between the performance of a CCD chip and CMOS.
Many have stated, that there has been a ton of information on this already. In reality there really hasn't been a ton of information on this. Look at the timeline:
Jan/Feb of 2014 the 250 was announced
Soon after DT released some tests taken indoors in a library
LuLa published a white paper by DT expanding on the tech and why the Phase
was special
I don't know of really any other tests.
Soon word of mouth spread about crosstalk and just how terrible it was and within a week or so, it was just an automatic decision that the 250/150 could not be used in outdoor shooting situations with movements due to crosstalk. But no one every really published anything showing this that I am aware of, if so please point me there. Crosstalk effects all sensors, or at least most of them, I know it effects the 260, as I can see the effects on blue skies with extreme shifts.
I for one GREATLY appreciate the posts made by Void has made for several reasons. As far as I know his posts and Guy's testing of the Credo 50 are the first ones to show that the 50MP CMOS chips can work with movements past 10mm outdoors. The time he took to both shoot all of this and then work it up into a well written post is commendable.
It has for sure changed my opinion on if I could use a 250 in my outdoor work, with movements.
Again, I find the use of the term "troll" very offensive in this situation and extremely short sighted. This is a public forum about medium format cameras and he has provided nothing but facts, facts that he has backed up with images.
I see the information, I can read it, and make my decision where it matters in my next purchase.

There is also testing of the CMOS back in action on Paula's Linhof Studio page.
