Thread: Firmware Upgrade for C700UZ

  1. #1

    Default Firmware Upgrade for C700UZ

    Hi, I think I ought to do a mini review on the firmware upgrade for the C700UZ. This upgrade was made known to me by Klause, who has gone for the upgrade too. Credit to Klause! Clap clap clap.

    The firmware upgrade is mainly to reduce the problem of hotpixels, which the C700 is infamous for. A preliminary tryout shows a tremendous improvement! The pictures below are all taken at F3.2, ISO100, One-touch WB. Sorry for the poor focus, I didn't set focus to infinity, but the emphasis is on the hotpixels anyway so please pardon that.

    2s exposure

    Underexposed, and zero hot pixels.

    Fullsize crop of the pic, showing part of the sky


    4s exposure

    Very minimal hot pixels.

    8s exposure

    hot pixels start appearing, but still bearable

    16s exposure

    hot pixels become quite prominent, but quite good for a 16s exposure!

    For the sake of comparison, the following pic was taken at ISO100, auto WB, F8.0, 16s. This was before the firmware upgrade, taken quite some time ago.


    Another improvement noted is: autofocus seems to be slightly faster, although this may be psychological.

    So in conclusion, this upgrade is definitely worthwhile! Just bring your C700UZ and warranty card to Olympus Singapore Service Centre, ask for Mr Goh. The upgrade took me 30-45mins. Mr Goh will also do an overall checking and cleaning, and will give a free booklet on digital photography FAQ (which is a bit useless). The service centre opens from 9-5pm, Mon to Fri only.

    Hope this piece of info is useful to all C700UZ users out there.

    Wow! Tweek, many thanks to your great efforts to conduct this hotpixel test! All I can say is simply amazing! The 16sec exposure pic was something that can NEVER be done before! Looks like the upgrade does make a difference.

    Btw, have you done the test on continuously using the DC until it is warm, and see if hotpixels appears to be as obvious as before?

    thats amazing..
    now i must look for that damn warranty card...
    it looks like they've got like an NR kind-a-thing, the hot pixels arent quite that lighted up as tehy used to be in 16s exposure, 8s even... dont htink its darkframe though...

    this is a must for all c700uz users i guess...

    Wow what does this mean for night photography. My enthusiasm for the c700 has alway s been high coz of the 10x optical zoom but then always dampened by the many users complaining about the poor night shot capability.

    More updates!

    Hello, what is the current version of the firmware for your c700? what is the latest version available? i have 78, not sure its the latest but i have no problem with hot pixels. focusing could be a bit faster though.

    How do you check the version? Breezebrowser doesn't show the version number in the EXIF data

    my version now is v357p-73...hmmm weird. Smaller number means newer??

    anyway azone I tried continuous usage...well there are more hot pixels but less than continuous usage before the firmware upgrade. So I guess it's still worth it after all....

    Hello Antena,

    Yes i remember you

    That is wierd that people getting firmware updage are getting version 357-73 when i have 357-78.

    You can see the firmware version in the xif datas. I wonder what this mean?

    mine says 357p-73... so i guess they didnt change the firmware version number... just improved stuff... i hope noise in ISO 100 is reduced too...

    my 2100uz is weird it just says Olympus Camedia Master, i only used camedia to transfer the images nothing more... oh well, it doesnt matter...

    Hmm.. yup, maybe the smaller the number, the newer the version?? Hmm.. tweek, to confirm, maybe you can check the version number (liek dianella said) from one of those pics you took before the upgrade and see if its really true.
