Never mind the toys, when are they bringing out a proper DSLR??


You mean besides the existing rebadged ones, or do you mean the KM's were
not "proper" DSLR's?


I mean the equivelent of a 9D that KM never managed to produce.

DSLR is different because it has larger sensor, thats why noise is not
an issue for DSLR


Noise is ALWAYS an issue, it's just the amount that changes.


That is why Sony uses a larger sensor AND in-camera postprocessing in
the H7 & H9 to drastically reduce color noise.

I would never want in camera post processing myself, but each to their own.
(dark frame noise removal can still be done in computer where you can make
the choices rather than the camera)

Good for technophobe photographers though I guess.

I think most camera manufacturers would disagree with you. In camera
dark frame subtraction is pretty common in good DSLR cameras to extend
the useful high ISO function of the camera, and can not be done as well
outside the camera.

Naturally, they want you to believe it makes their camera somehow special.

Of course it can, what makes you think the crappy computer in the camera can
do anything a real computer can't?

Not special, just sensible.

Dark frame subtraction isn't about high ISO, it's about longer exposures at
any ISO.

Of course it can, what makes you think the crappy computer in the camera

Well, it _could_ be done outside the camera.

But it would be seriously dumb to do it outside the camera. The operation
itself is a trivial subtraction operation, and to do it on the computer
you'd have to store two full raw frames for each image. And read them onto
your computer and do the work there. Work that could have been done
trivially when the image is taken.

If your camera doesn't have that feature, it would be seriously dumb to
think you can't do it at all.

As with every tool, it all depends on the circumstances. Sometimes in camera
processing is the most convenient for sure.
There are times when shooting lots of photo's and one or two dark frames is
quicker than doing a dark frame for every shot though, assuming your camera
even has that feature.

However I never said that the in camera method wasn't useful, just that I
would not buy a particular camera simply because that was an advertising
feature.

With Sony you have the choice of doing it quickly in the camera or doing
it in your computer if you use .raw. It doesn't work nearly as well
without raw.

Of course, I hadn't even considered you might think otherwise.

Then why did you say:

It is like about 90% of the features on the camera. They are there if
you want them but you never need them, you can ignore them. The reason
I buy a camera is because of the features I want, not because it doesn't
have the ones I don't want. Why would you mention a feature you don't
want. It doesn't affect anything. Some people do want it.
