Anything based on DCRAW will convert the Canon 7D2 CR2 files.

I didn't check to see exactly, but the usual thing is that
DCRAW only checks the manufacturers name and the model
for the specific number of characters. Hence a "7D" is
what it will see, even if what is there is "7Dxx no such camera".

As long as the parameters are the same as the previous
model, the resulting conversion is just fine. Often
there are small problems to start with due to small
differences. In this case at least there don't seem to
be any, as the above CR2 file looks exactly as one would
expect. I tried both DCRAW 9.22 (July 3, 2014) and the
current source code release of UFRAW.

There is no "7D mark II" in dcraw.c. The 7d2 do not have same sensor as
the 7d. I guess that you're a wizard. Anyways, that would be an ad hock
solultion and not a calibrated conversion.

There need not be a "7D mark II" in dcraw.c, as it only
has to find "Canon EOS 7D" to process the image using the
algorithm identified with that label.

The sensors may well be different, but the
algorithm works the same with either of them. And it
does produce a very appropriate conversion. I'd note
that *every* raw conversion is an "ad hock solution",
almost by definition!

Will it be slightly different than what will be produced
a few weeks from now when Coffin adds the new model...
of course. But not enough different that you'll be able
visually detect it.

that's a bug.

"Canon EOS 7D" != "7D mark II" (or whatever the exact labels are).

works and works well are not the same.

the arrangement of the pixels might differ, the chromaticities likely
differ and certainly the amount of noise reduction, sharpening etc.
needed will be different.

that *every* raw conversion is an "ad hock solution",
almost by definition!

that's a stretch.

maybe you won't, but other people will, especially if there are
significant changes to the sensor.

not everyone is satisfied with substandard results.

if it wasn't noticeable then there would be no point in updating raw
converters for new cameras.

In the opinion of who? You! Good for a laugh or two...

None of that is true.

That is a fact.

The point is that in this particular case there are not.

not everyone is satisfied with substandard results.

Only you are. Others can tell when results are not
substandard.

converters for new cameras.

Talk about a stupid comment. You don't seem to have
understood the difference between what applies to this
one specific case and what applies in general.
