I have been contemplating buying a Pentax Ist DS or a D50. And in
PHIL'S REVIEW of the DS he showed resolution problems with JPEGs. I
emailed Pentax and they said there probably wouldn't be a fix (BTW
I am a Pentax SLR user so I do have a bias toward Pentax). It kind
of shook my confidence in future support of their products.
By doing a Nikon D70 firmware update, I have greater confidence
that the D50 will be suported in the future, making it more likely
that I'll buy a D50. It is not just D70/D70s sales that make
increase because of this support but their other models too.
