Hi,
- I would say that base ISO seems to be around 35 for the 80 MP backs.
- I don't know if full frame CCD has great dynamic range, that may depend on definition of both great and dynamic range. What I may see is that MFD systems tend to underexpose and thereby protect highlights. For instance, the default film curve in Capture One makes image very bright.
- Readout noise is higher on CCD, so the darks are noisy.
- Yes 16 bit is indeed awesome, but so is 14 bits and even 12 bits.
For the kind of work I am doing my P45+ is mostly quite OK, there are exceptions, however.
Best regards
Erik
You can always ignore the ISO 35 setting and deliberately give more light for ISO 100. ISO 35 will not give you better image quality. Without ISO 35 you can still achieve as good image quality if you shoot at ISO 100 and give the same light.
For your use case in the studio, the ISO 35 setting is merely a "+1.5EV exposure compensation for flash" for people like you who have no clue about what is called native ISO. You can dial +1.5EV exposure compensation for your flash and use ISO 100 without relying on ISO 35.
Common superstitions for MFDB:
a) ISO 35 is great;
b) Fullframe CCD has great dynamic range and latitude;
c) 16-bit is awesome.
None of these three is true. It cost me a fortune to realize these.
