Out of curiosity, how was Adobe able to update the DNG converter and ACR to work with the D850 the day it was released if they did not get advance information or there was a change to the format you have been talking about Andrew?
Did I say that in this case, they didn't?
Is this historically the norm? No. And what about 3rd party raw converters that don't support DNG; did most have a version available on release day? I'm not a Nikon shooter (at least not recently) so I honestly don't know how long any of this took for this Nikon model but my desire would be at the
very least, customers would have a DNG Converter that understands the new file
the day that file becomes released to it's customers. But for non DNG users, they are still SOL here . Again, this is political, not an issue that couldn't be addressed with current technology. Until the customer base makes their desires made to the people who make these products, nothing will change.
