Re: [Digital BW] 8 bit to 16-Canon G2 is 16 bit

2002-05-27 by Robert Morrison

Yeah...its a tough call between these two...more resolution (5 vs. 4), wider
angle lens (28mm vs. 34mm) and higher max shutter speed (1/4000 vs. 1/1000)
on the Nikon side, and 10bit Raw format, faster lens (f2 vs. f2.8) and
cheaper on the Canon side.  Honestly, I can't image that 10bit RAW is that
big an advantage over 8bit TIFF in image quality...but the smaller file size
probably helps for those not running 1gB microdrives.

I recently started looking for a prosumer smaller camera that was more
portable than my D1x and decided there wasn't anything out there to
buy...everybody seemed to have some fatal flaw.  I really liked the specs of
the new Leica Digilux 1...but then the SD card issue killed it. I wonder
what Coolpix 3 is?  It is due to be announced on Wednesday.

Its ironic...I've switched to digital for much of my "serious" work...but
when it comes to having a camera always with me...I'm still thinking about
shooting film.
