    i,m still getting used to the camera,

    I feel that for 90% of the shots any ISO setting above 400 is not really worthwhile

    Bill,
    What camera are you using? What do you expect in terms of an image?
    I use the Pen 1 all the time at 2400 or there abouts and the results are wonderful....

    It would help to explain more and maybe post an image or 2 that you feel shows the problem...
    Don't sweat it Bro'...we're all here with you and we'll figure it out...

    I have just been "playing around" indoors with a nice Nikon 35 f2 the Nikkor O-C which I have never been able to use on my D300 because it is NAI
    Seems a very good lens - I have "binned" all the shots i took at ISO > 400 as I thought that they were terrible - but I will take a few more next week and try to post something sensible now that I am getting used to the G1.

    I am more than happy with the high ISO performance from the E-P1.

    ISO800 here...

    4094566441_1641d1b3cc.

    A couple of ISO3200 shots...

    I wonder why the GF1's high ISO performance is not as good... can't really shoot in color over ISO800. Can this change with a firmware update?

    Possibly but I don't think it will happen. Panasonic prefers to concentrate on maxing the detail while Olympus prefers to shove user friendly JPEGs out of the camera. At the pixel level, the Panasonic image looks very good with an astonishing level of detail.

    The Olympus, at pixel level, can look distintly hacked but it will print out very well at normal print sizes and looks great when viewed at normal screen sizes. The Olympus does better with noise handling but trades away detail. In my opinion, it is probably one of the best compromises out there. The Olympus probably has a minor edge in colours and white balance but there is not much in it there.

    Then again, Panasonic trounces the Olympus with AF speed.

    Compromise, compromise, compromise.

    What about images shot Raw and then processed in ACR, Lightroom or some Raw converter. Are the differences in noise performance still substantial?

    I keep my NR to low on my pen. This seems to balance noise and detail for me.

    The Pen raw files do very well at high ISO.
    The noise is fine in b&w up to and maybe above 2450.
    I have done many images at 3200 and pushed to 12800.
    In color you should be able to get 1250 easy.
    Since I started the Pen...I haven't used Noise Ninja at all. That's how good it is.

    Cosinaphile has both cameras and he maybe could join in with an educated point of view.

    I try not to take high ISO shots! :biggrin:

    Anyway, this was taken at ISO 1250, the noise is still visibile in spite of Lightroom NR (I'll post it large to show it):

    I gotta show my age here......
    Youse ever shoot film? You could never get these results with film.
    I mixed my own developers and learned how to cut grain but digital just blows it away.
    Think grain...not noise....

    Here is a photo I took the other day of our dog. I didn't even notice the ISO speed until sinophilia pointed it out to me over on flickr. It was shot on my E-P2 @ 6400 with the Panny 20 @ 1.7 and I was trying out one of the "art filters". I'm pretty sure it was the "pin hole". 4301242295_9f2f3d473a_b.

    Have you tried this with the new Lightroom beta version. What I see in your image is chroma noise and in Lightroom beta they claim to have implemented a pretty good chroma noise reduction. Maybe that could help.

    Cheers

    I have just left the E-P1 on its default noise reduction settings and shoot JPEGs. I haven't been able to get a better compromise between detail and noise out of RAW images so don't even bother with them any more.

    I would need to apply any sort of noise reduction to my images (even ISO3200 ones) at a rate of less than 1 in a 1000.

    What I have noticed is that from time to time, there is a little more noise than I would expect at low ISO. I belive that is due to the dynamic range enhancement process which I have left on auto. BTW, I don't think the dynamic range enhancement works very well at all.
