- The statement is true (the A/D convertor is 16 bit).
- The implied advantage is true (that the file has more tonal smoothness and holds up to post processing better).
The specifics of the entire imaging chain and the usefulness of comparing using a 16 bit vs. 14 bit convertor in any given camera are quite complex and include proprietary and very in-depth knowledge (e.g. are all 14 bit A/D convertors identical in impact on image quality when placed into an imaging chain, are there any additional effects that need to be understood when adding in proprietary dark-frame subtraction technology, do all A/D convertors produce identical amounts of heat and are all available in the same physical sizes/shapes, are competing "14" bit systems using all of their "14" bits fruitfully).
We frequently have very in-depth technical conversations (as full and frank as we have knowledge/experience to offer) with the customers who are very technically minded and interested in such things.
Usually though we simply send raw files or have the client test (in the real world) the camera they are considering so they can make their own conclusions.
Bottom line: if someone buys a digital back because they have been lead by the graphic to expect better tonality and file robustness they have
not been misled. So I think for marketing purposes it's a fair distillation of the product features.
However, this thread has convinced me the use of the word "true" was not the right way to go. I've
updated the graphic accordingly.

The end of the year is extraordinarily busy for us (tax law in the US means a lot of photographers make equipment purchases at the end of the year) so I will likely not be on LL the next few days. Please don't interpret this as avoidance - I think we (Capture Integration) have shown repeatedly we want to be a transparent and honest dealer.
