Hi Mat,
What you miss, is that distance between the exit pupil and the sensor is in all probability large because there needs to be place for the mirror.
On a camera without mirror that often is used with symmetrical lenses with exit pupil close to the sensor it makes sense to optimize the sensor for the large beam angles that may result, but much less so on an SLR. With SLR lenses there is simply no issue.
Tilting the lens may cause a problem, but again, SLR lenses used to have limited tilts. Indeed, Canon and Nikon T&S lenses work well on digital sensors, including the IQ-250.
So, the design of the CMOSIS sensor solves a problem on M-series Leicas and possibly studio type of cameras if Leica will make a sensor for Sinar. But that problem is simply not there with DSLRs.
The downside is really that competition is now at 50-80 MP, while the S-series is limited to 37.5 MP. The combination of sharp lenses and large pixels is also prone to moiré. Whenever you get moiré, colour or monochrome, it is a clear indication that the lens outresolves the sensor - showing fake detail instead of true detail.
Best regards
Erik
Why do you think it makes little sense on a DSLR Erik? The Leica has a tilt shift lens in the lineup and also is compatible with the Sinar P series, it seems like having a sensor with no colour shift or cross talk is exactly what is needed, unless I'm missing something from the technical/engineering side of things?
