  2. Hi Andy, How long have you had the D70? Being a new release it can't be
    all that long, but I found it interesting that you have dust on the sensor
    already. (Seen easily in the tree shot) I hope it does not turn out to be
    a dust magnet for you.

    Also what lens was used for that shot, as there is a bit of fringing going
    on?

  3. OK... ignore the lens question, I have now looked at the exif. :)

    He also says on the page that the dust is on the lens, not the sensor.. (but
    I find that hard to believe, never seen any dust on the lens create that
    sort of blob...)

    I had a brand new fuji s2 that had noticeable dust on the sensor out of
    the box. I think quality control is dropping on a lot of new camera gear...

    Cheers,

    Does anyone else think the shots look quite noisey for ISO 200?
    Considdering teh excellent noise levels of the 300/10D at ISO400, I am a
    little worried.

    The noise doesn't look much like a JPEG issue.

    Danny.

    That's what I thought too, particularly noticable on the
    <http://www.users.bigpond.net.au/andyz/d70-08.jpg> shot (which I think is a
    particularly nice compostion BTW)

    I don't suppose that the noise would adversely affect a print, but it is
    definently /there/ and moreso than it's Canon counterpart.

    The level of noise wouldn't bother me, though it does make me wonder how the
    performance is at faster ISOs.

    Image
    Looks more like the compression of the JPG than noise. That particular
    file is 1.5mb. Does the D70 use something else to make JPegs that size
    from a 2000x3000 pixel image. ( the D100 usually is another 1Mb bigger
    at 2.5Mb) Dark images are small but never that small.

    What does the card image capacity spec read for 100Mb?

    Dirt
    As for the dirt on the sensor you will either have to get someone to
    clean it off or sensor swabs. I found that blowing it off does not work
    unless the sensor is sparkling clean in the first instance which it
    obviously is not. It would seem that there maybe a residue on the sensor
    which needs a alcohol based solution to clean that off first. After I
    cleaned mine with eclipse fluid, dirt has not been attracted to or
    sticks on the sensor.

  9. I agree.... it looks like sensor dust to me.

    Hi Russell

    I got it the night before posting the shots, so Its 2 days now.

    Im not sure what It is, I took the lense off and cleaned both sides
    (front glass and rear of the 18-70), there was a few noticable bits of
    dust on the rear glass. I will take more shots and post, When I got the
    camera I just put it together and started shooting but I purchased a
    blower brush today and cleaned it all up a now, hopefully it should be
    better.

  12. The image is sharpened considerably and this in itself will produce noise.
    Personally I think noise adds some character to an otherwise bland vista in
    some photos.

    Yes It was, I had a look at the ccd and there it was, dead smack in the
    middle. 2 second job to get it off and pictures are fine. The images on
    the web are all compressed at medium quality using photoshop, the real
    images are about 3 - 4 megs each and are very clear. I will try to get
    an uncompressed image up when I get more time.

  15. I am quite sure it's dust on your sensor, BUT...whatever you do, DON'T put
    that blower brush anywhere near your sensor! Some have tried and ended up
    with more dust than they could poke a stick at.

    Agree great shot!!
    Images have been reduced. Site states:
    "I have posted the photo's at 70% of original size as It is too much space
    for my site (10 gig). Details off the camera are added below each thumbnail"
    Even if resaved on PC as same size normally has greater compression than
    camera.
    Looking at these pics and feedback, looks like more evidence to point that
    my 10D also has dust on sensor - pretty much from beginning out of box.

    AGREE !

    Anyway how many lens are you using ?
    IF you are only use the AFS 18-70 AND it only ... seeing a lot of dust came
    in .. I doubt the F mount seal is any good.

    The image (d70-08.jpg) size was still 2000x3000 and now you say it was
    compressed further in Photoshop which explaines the 1.5Mb file size. So
    the "noise" is actually relates to jpg compression.


    Does the D70 still make the ~2.5Mb jpg files?

    NEF (raw) = 5.0 MB

    In JPEG Fine mode -
    Large = 2.9 MB
    Med. = 1.6 MB
    Small = 0.8 MB

    The noise doesn't look at all like JPEG compression artifacts to me. It
    looks like sensor noise.
    (someone said that the images have been heavily sharpened - that seems like
    a plausible
    explanation for the noise being magnified somewhat)
