Many recent reviews say nikon DSLR has better noise reduction than canon
DSLR in high ISO photos.

Why isn't canon doing something about this? This has been going on for more
than a year.

Because Canon has been working for the last year on a new noise-free
sensor that can take a smooth picture of a room full of 50 people
illuminated by a single candle. ISO equivalent to 480,000.

They also say that the difference is quite small.

What makes you think that they're not?

Oooo! A whole year! And how long do you think that the development
cycle is on a new camera? I'd guess that its about two years. But
most people care more about the number of pixels than about a slight
difference in noise for low-light photography.

Too many people think that one particular feature of a camera is the
most important thing in the world and ignore all the other hundreds of
features. Camera makers sell to more than just one person in order to
stay in business.

I believe this is an assessment of the in camera noise reduction for jpegs.
Shoot raw and everyone has the same control, no? FWIW, I shoot Nikon,
D70/D200/D300. Just spent most of the morning having to shoot mostly at
iso1600 due to a totally cloudy sky and general lack of light.

depends on the user. someone shooting indoor candids, theatre or
sports might use high iso a lot. someone shooting landscapes probably
won't.

actually, they have. recent dslrs have 14 bit a/d converters.

if you blow the highlights, they're gone. if you underexpose by a stop
you'll have more highlight headroom.

For the last year Canon has been assembling
a crack team of Ninjas so that when the time
is right they will use this team of crack Ninjas
to distribute a new camera with improved
ISO performance.

Cheers.

No it isn't - not when raw files are tested.
High ISO NR level for in-camera jpeg can also be changed. Though I'd
agree that the default setting high ISO NR level is too high, if that's
what you mean.

No. Sensors and processors have improved markedly over the last ten
years. Even RAW formats have to be converted to numbers in camera so
some RAW images are more equal than others.

Using a D300, I find I am losing my dislike of shooting at higher ISO.
I only think once before shooting at 1600. I find the benefits outway
the problems of larger lens apertures and slower shutter speeds. I
have been known to shoot at even higher ISO :-)

A few years ago it occurred ot mne that comanies like Canon and Nikon
could make money by selling firmware updates that added significant
new features to existing cameras. The firmware hack for the Digital
Rebel is an example of what they could have done.

Of course, the executives who run the camera divisions for these
companies are outdated morons who still haven't yet clued in on the
computer era and have not chosen to embrace this possibility.

As one falls behind the other they get motivated.
