Offended or not, it's pretty obvious that there's been a huge disconnect between lens designers, sensor designers, digital back designers and dealers.
The SK28 is a mystery from a lens design perspective. Designed just a few years ago it only works with Kodak sensors, and even there it pushes it more to the limit. Clearly the lens designers did not even check how digital sensors work, or hoped for some new technology to arrive in the future sooner than it has.
Then there's been myths of what color cast is at all. I've heard things like because MF sensors are so incredibly sensitive they record the color of the coatings from the lenses. For a layman it may not sound too unlikely, the magenta color of the coatings kind of look like what you see on the LCC shot. I don't really know from where the myth comes originally but I can imagine an ill-informed dealer tried to answer a customer question.
Such myths would never appear if there's been connection between lens designers, sensor designers, back manufacturers and dealers. But instead it seems like everyone has half-hearted tried to figure it out on their own with limited success.
Crosstalk is not just a catchy name, it's the correct technical term of what is happening, and the problem is has become worse for each new sensor generation, and is now peaking with the Sony CMOS sensors. Crosstalk differs from regular color cast (which is afaik caused by pixel vignetting variations due to unevenness of the pixels) in that it cannot be restored with the normal LCC process, therefore it's very important.
Before 2014 I have not ever seen a dealer mention crosstalk a single time. Then the IQ250 was released and tech cam tests showed real odd LCC failures, so I started reading technical papers on sensor design and found out the crosstalk metric and then all fell in place, these strange LCC failures were of course crosstalk. Learning more about the particular sensor designs and looking at microscope images of the sensors it became obvious this was a large problem. I even designed a crosstalk cancellation algorithm that could reverse crosstalk in some cases, but unfortunately not in as huge amounts as we see on the CMOS sensors.
It's also obvious to me that Phase One have never informed the dealers about what crosstalk is and why it cannot be corrected with LCC, and which problems that lead to. You have to excuse me but I don't believe that dealers "have known all along", nothing in all I've read and heard indicate that, and if they did know they have not been honest in the information to the customers. That people know about crosstalk now is through the information campaign I've had on this forum and LuLa.
These systems are not $500 cameras, it's $50k systems. I think customers can expect that designers, manufacturers and dealers are fully aware of technical limitations of this kind. This has not been the case, things have just been slapped together and hoping for the best. Then I think the least you can expect is to get criticism.
For similar reasons like the SK28 this Cambo Actus is partially a design mystery. It's clearly designed for CMOS sensors, but there are no good wide angle solutions available. Sure you could use it for 50mm and up, and not shift the wides. But the attraction of such a small compact camera is of course to use it outdoors and shoot landscape and architecture, and what is that without wide angle lenses? My assumption is that just like lens designers at Schneider Kreuznach that made the Digitar 28, the designers at Cambo designed this camera without fully understanding the crosstalk issue.
