Jeff over at Dcresouce has posted his OLy410 review:

My personal opinions - the pics with NR off are cracking and a pity that Oly's software is still a pile of ...

My observation; check out these ISO 800 samples:
(if links give an error at first, just reload)
NR Standard=D80

NR Low = XTi

NR Off kills A100

I load these all in different tabs, pick a part of the picture to compare, align them all, and tab between them to judge. I've seen the same thing now in maybe a half dozen professional review comparison shots. The imaging resources tests (review not yet posted), cameralabs, dcwatch, pixelmania, now dcresource.

The nice thing about this is, the forums as a whole seem to be alot less plagued by pixelpeepers making too much out of small diferences in image quality--now that Olympus actually seems to be winning many of those comparisons.

Hi Ken

I've been really impressed by the new nMOS sensors from Pana and with the NR set to low or off the IQ is spot on. Looking at all of the sample shots so far, I much prefer the NR off shots - they look sharp and punchy and remind me of the files produced by the M8's Kodak sensor which has no AA filter. In terms of noise and resolution there isn;t much between the new 4/3 sensors and the current 10MP APS-C CMOS or CCD sensors from Canon or Sony, except that the new Pana sensors seem to be sucking in lots of detail :G . The only thing that has been pointed out by several sites now is that ISO1600 is actually ISO1250 and that there's been a slight loss in DR, but personally I could easily live with both. I'm really looking forward to seeing how the E3 pans out - will it be a souped up E510 or a real step up from the E410/510, which would be even more impressive.

Cheers

Harj

hey Harj
not so sure about the iso implications
elsewhere theyve been saying that 100iso is actually iso125
which means its not the 1600 end thats out at all, but the baseline
theyre going to do some tests, Ill give him a few days and husstle up

also the DR thing for 410 was from Askey, where i have a trust issue
he would have used default metering, so who knows
it seems there are some sample variations between cameras, and some 410/510 have real issues with blowouts, some do not


outside of that, check this guys stuff out with a 510
much of it at iso800 indoors
freaking nice ambient light photography

Oly really is in the groove this time around

Hi, Riley

It seems to me that from a purely quantitative viewpoint, assigning an ISO rating to a digital sensor is ambiguous at this time. ISO Standard 5800:1987 is for negative films and although I don't have a copy of the standard it appears to require measurement of thequantitative relationship between density of the negative and an ISO rating. Butwe all know that was baloney - no one ever shot Kodachrome at the rated ISO. As far as I can tell there's no updated ISO standard for digital sensors.

Nevertheless it seems to me that folks who concentrate on reviewing digital cameras in a professional way, could get a good feel for the "accuracy" of the Oly E410/510 ISO ratings simply by setting up a studio lighting situation, setting the Oly to spot metering and comparing the Oly recommended exposure to that from a pro-quality spot meter, being careful to account for the relative sensitivities of the camera and pro spot meter to the lighting temperature. If I had that kind of equipment I could sure get a good enough feel for the Oly ISO ratings to satisfy my own curiosity <grin>.
