Any opinion on the published D80 images? If those are true, then IMHO Nikon has taken a big step to bring usable NR in their cameras.The 20D, 30D and Rebel XT all have at least 1-stop of high-ISO
performance over the 10MP Sony sensor (in the Nikons and Sonys).
These I think some are quite promising / threatening however you want to take it http://photo-cafe.jp/scoop/index.html
But then the images here are perhaps not so good http://hardwarezone.com/articles/view.php?id=2016&cid=15&pg=7
So at least I'd wait till some competent done review (like Phil's) before saying anything.
The 5D has another stop and a third over that at the same level of
detail or another half a stop with a huge detail advantage.
The 10MP sensor has a very tiny detail advantage over the 8.2MP
Canon sensor. It should be more but it isn't.
The 5D has a huge detail advantage over the 10MP Sony sensor.
So, if you shoot in good light, the Sony sensor might be a good
alternative if you like the Sony or Nikon systems. In bad light,
the Canons still rule the day, and by a big margin.
Personally, I still feel Canon has a big system advantage overall.
More IS lenses covering a wider range, usually at lower cost
(especially the long primes), lots of short to medium primes with
USM (24/1.4, 28/1.8, 35/1.4, 85/1.8, 100/2, 135/2), a fast high-res
low-noise body (1DII series), and the opportunity to move up in
format size if you would like to (5D and 1-series). I carry a 20D
and 5D with 5 lenses, using them differently on the two different
formats. No other manufacturer provides that capability.
Canon does need to do more to attract the brand-new dSLR customer
which is what a lens like the 18-200VR does. People are also still
fooled into believing that more MP = better image quality which is
sad.
