The 16 bit issue, truth or myth?

One of the claims oftem made for MF is the use of 16 bits. The simple truth is that this is pure nonsense. The number of useful bits is the same as DR. As we have seem above, DR for MFD is around 11.5 EV while for DSLRs it can approach 14 EV. It is very much possible that MF backs use 16 bit pipeline. This may be due to the fact that standard components are normally 8-bit, 16-bit, 32-bit or 64-bit designs. A 12 bit pipeline cannot be built with standard components. DSLR vendors use ASICs (Application Specific Integrated Circuits) optimized for the available data. MFDBs use a 16 bit pipeline to transport 11-12 bits worth of data. So talking about 16 bitness is a marketing truth, in common speak known as a lie.
