How do you know this? I was not able to find reviews, much less
head-to-head comparisons anywhere. Did Fuji really get it right
with the F10/11, then blow it with subsequent chipsets?
Actually, they didn't blow it ... rather, they were handicapped by two things:
1) E900/S9000z -- 9mp on a sensor about the same size as the 6mp sensor in the F10 is pretty much going to guarantee more noise. Fuji knew that but they needed to compete in the high mp bridge category.
2) S5200 -- that 5mp sensor is not today's chip ... so it just cannot quite compete with either of the others. Still, Fuji has very good noise processing and has been able to offer 1600 ISO for the first time on a chip like this.
In order to demonstrate why I have come to these conclusions, I've put together a little compendium of noise graphs from
http://www.digitalcamerainfo.com ... this juxtaposes a number of cameras to see how their noise performance compares. The graph first, then my interpretation of the results. Note: when readig the graph, note that the Y axis is not always scaled identically, so you need to look at each point individually to see how the cameras stack up.
My interpretation of the cameras in order:
1) D50 -- the winner by far. The best noise measurements at every ISO. Wow.
2) Rebel XT -- An excellent sensor. Interestingly, it blooms a bit at 800, letting the F10 slip under it, but regains the lead again at 1600. Note that the F10 has higher in camera noise reduction, so I think the visual quality of the Rebel XT's noise is better at the same measurement level.
3) F10 -- huh? What is a tiny sensor like that doing here? Well, that's what the fuss is all about, isn't it?
4) Rebel -- just squeaks in ahead of the S9000z. But definitely behind the F10 by a more than a hair.
5) S9000z -- well done! At 800, it's still very low noise (although much higher than the F10.)
6) S5200 and E300 tie -- The SLR starts with lower noise, is a hair better at 800, but worse at 1600. Wow! Again, it is possible that the visual quality of the noise is better on the Oly. But they are too close to call by the measurements.
7) F828 -- not great ...starts pretty low at ISO 64 (or 50, can't tell on the graph) then rises rapidly. A hair less noisy at 800 than the S5200 at 1600.
8) FZ30 -- starts really poorly ... finally competitive with the F828 at 400 ISO. Low or even moderate noise is just not this camera's "thing".
Summary
======
So there you have it ... the buzz is real ... the results are amazing ... and if you want more features and still want the ability to shoot pictures inside theatres, museums, parties, and so on but do not want a dSLR for whatever reason ... well, the answer is still Fuji at this time.
