    TZ1 flash off sync with shutter

    Hello,

    My new camera had been great until very recently when all shots involving the flash became unusable.
    When i take shots with flash, the flash activates well before the shutter, producing horribly dark photos, or the shutter closes with the flash but produces extremely washed, over exposed photos.

    Which of these happens appears to depend on what i am shooting at, but i can get either situation to occur just pointing it at different areas on my desk.

    Here are some examples:

    Any help would be GREATLY apprechiated as, at the moment, my camera is competely useless in environments requiring flash.

    While I do not know how a TZ1 operates....the problem with those 2 photos is easy to see.....but why ,I am not sure.
    The overexposed one is spot meter...ISO400....
    and the dark one is pattern meter and ISO100.....you need to get those 2 things consistant and then see where you stand......It does not seem to be any sync problem but the settings are too different.

    If you spot meter on a dark spot the photo will be over exposed plus the ISO will also over expose a photo.

    They both say auto exposure and normal program so I am not sure why the different settings.

    If the TZ1 has a flash compensation and you raised the comp...that can raise the ISO.

    A question ..are you sure you need a minus 1 exposure compensation on the tizzy?

    Wow amazing how you can analyse so much from just those photos.

    Yes i had -1 exposure on, but that was just in an attempt to figure out the problem.

    I am new to photography so am quite confused by this issue, but it occurs even on 'simple mode' where everything is supposed to be automatic, which makes me believe it is something more than just user defined settings.


    But in regard to the flash activating before the shutter, it goes off and about half a second later the shutter closes. Surely that is not normal..

    Oh I just read the exif, no magic there....about the shutter while I do not have a TZ1, it is probably doing a dark frame subtraction that makes you think the shutter is just closing......
    There are other things that can make you believe the shutter is not working correctly and I do not know if the tizzy has them and/or if your using them.
    One is slow sync and the other is the redeye thing....turn them both off and try again.
    I hope someone using a TZ1 will offer to help.....Until they get here I would reset the camera to factory defaults and it should take a decent flash picture.

    Believe me, the spot meter on a dark spot will cause a bad overexposure...
    On a lot of cameras if you go to an auto mode it will not allow you to choose spot meter and will set the ISO on100 for you unless you choose to increase the flash brightness and then it will raise the ISO. the over exposure is I believe very easy to explain but I am not sure about the darker photo.

    I looked at the exif on some other TZ1 flash pictures and the camera seems to pick an ISO between 125 and 165 for most flash photos....neither of yours are like that......Perhaps reset the camera to the defaults.

    Osiris,

    I bought the TZ1 for my wife in June. Two weeks ago she complained about the pictures it took of her cousin's wedding shower. Most came out horribly underexposed and noisy (even for a Panasonic sensor.) When I played around with it, I came to the same conclusion as you; that is, the flash seemed to be out of sync. I also noticed very inconsistent ISO "choices" by the camera in full auto mode. Exposure compensation did little to fix it.

    Since my wife is not the type to use manual ISO, etc., I called Panasonic customer service. After returning the camera to factory settings several times, I finally convinced the second operator that something was wrong. I shipped the TZ1 off to Bigston in IL, the only digital camera service center for Panasonic. That was a week and a half ago, and all I know right now is that they have the camera. I will keep you posted, but for now I think a call to Panasonic customer service is in order.

    Hmm thanks for the advice.

    I am slightly worried though as it was bought from a friend for me in Hong Kong so i am a little unaware of the coverage of my warranty.

    I'm from the UK myself, finding it a little difficult to find a UK service number to call..

    Could it be the subject(s) were out of flash range?

    That's possible, although they were no more than 10-12 feet away. I took some pictures at 2-3 feet at the wide end of the lens, and they turned out like Osiris's - either extremely overexposed or underexposed.

    From www.panasonic.co.uk:

    "If you require service, Panasonic UK has introduced nationwide Service Centres which will be able to effect repairs in or out of guarantee. There is one telephone number (below) which will automatically route you to the nearest specialist service centre. They will then be able to arrange collection of your unit. They offer fixed hourly charges and a fixed transportation fee.

    0870 906 8357

    We do, however, recommend that you call this number from a domestic telephone line, preferably at your own home."


    Also, I just got off the phone with the US service center, and a part is on order under warranty.

    This data is from Reviews & Info on DMC-TZ1
    Flash range (Wide/Tele, Auto ISO): 0.3 - 3.7 m / 1.0 - 2.4 m
    1 foot = 0.304 meter. So a subject just over 10 feet away could be out of flash range at the tele end.
