    M8 Image Question

    I was wondering if someone could explain to me what is going on here and if it is considered normal for the M8 ? Thanks in advance for your input ......

    ISO 640 / ISO 1250

    Re: M8 Image Question

    Do you run very old firmware? Might this be one of the very first M8 cameras that has not had its factory recall?

    The first image btw is just reflections in the filter. I am referring specifically to the banding in the second shot.

    Re: M8 Image Question

    Thanks JAAP,
    Firmware 2.005
    The reflection is from the filter, which of course makes total sense ...; )

    So is the banding caused from a faulty sensor which there was a recall for ,or is this just a quirk of the M8 ?

    Hi Charles,
    I do think that the M8 sensor can be prone to some banding at "higher ISO's", to the point where I generally avoided ISO 640 when I had one, though I could use it if pressed into service.

    The series 3100001 - 3101500 had a recall to add a mass contact for banding.

    That is basically correct, although the banding is more or less limited to under-exposed high-ISO images. The type of banding we see in this shot, i.e.strong stripes emanating from highlights, is very reminiscent of the effects we saw late 2006.

    Re: M8 Image Question

    a little late... but what are you using to process the images?

    i found that makes a huge difference, too, especially at high ISOs.

    i'm one of those who shoots at whatever ISO i need -- which means, yes, far too frequently i go into the 1250-2500 range

    i've had pretty good success with using C1, along with Jamie Robert's profiles (even when i use IR filters).

    Re: M8 Image Question

    Just wanted to follow up on this ... Thanks for all the comments here and the help from behind the scenes . Don Hutton took the time to send a few RAW files to Leica on my behalf . The camera checked out and according to Leica the camera is working as it should. Apparently when shooting at the higher ISO's on an M8 with a bright light source in the scene will cause this if the image exposure is not right on . The over exposure of the lights is what is causing the streak . I went out shooting last night in china town and had maybe one or two images that had the streak ,the rest of the images were fine . Thanks again Don , JAAP, Ashwin and Cam ...

    Aloha ,
    Charles
