Hi, i'm new here, and new to this camera.

When I set the appature in creative movie mode indoors (dark) I can set it to f4.0, outside in bright light it won't open higher than f5.8 no matter what shutter speed or ISO i set it at. This is with stock lens of course.

This is updated firmware Jap model.

Also, it seems to radomly only let me shoot 10 second clips in 720/60, all other formats fine, but sometimes in 720 mode, its stops after 10 seconds and gives a message on screen in Japanese, I have no idea what it says, but it stops me filming.

Class 6 16gb hcsd card, so can't be that and 1080 is fine. Really annoying as 10 seconds is nto really enough.

Any ideas?

When you were shooting outdoors, was the lens zoomed in to a telephoto shot? You can only open the aperture to f4 when you are zoomed out wide on the kit lens.
As far as the problem with 10 second clips, I have no idea.

Hi Lauri: This is most likely caused by that particular card. Barry Green & other GH1 users here have stated that even a properly designed & manufactured Class 4 SDHC card is fast enough to work in a GH1.

If possible, do a test using at least one other card. Perhaps a friendly local retailer will let you try a card before you buy it?

If you haven't already tried it, reformat your SDHC card.

You might try the GH1's "reset" feature (p. 36 & 173 in the English-version of the user manual).

Let us know what you find out.

I'm kinda cringing at this... "Japanese" would have been a more appropriate word to use, especially as this is an international forum.

Cheers,

Hi I used 'jap' as short for Japanese, the same as i might use 'Brit' for Brittish, I wouldn't be offended by that, sorry that you are, thanks for the useful advice though.
 
Hi Lauri

Most zoom lenses vary in aperture, closing up a little towards the end of the zoom range. The GH1's kit lens goes from F4 at full wide angle to a little slower F5.8 at the long end.

The 10 second limit in 720p mode seems to be to do with the memory card - try formatting the memory card in the camera, (the menu icon with the pencil and paper). Have you updated the firmware on the lens as well?

Ok, reformatted the 'Patriot' 16gb class 6 I imported from USA about a year ago, seems to have fixed it (though I can't tell yet as it was a bit random). And also got my Genuine Panasonic 6gb class 4 out of my other camera and will try that.

I can't beleive the speed of these replies and how helpful you all are thanks!

OK, I'm going out to try and shoot something before it gets dark......

Hi Lauri: Welcome to the Internet. You have a "girl" name (or, especially to many Americans, it appears girl-like). In online forums, that all but guarantees lots of replies. :2vrolijk_08:

However, if you're not a girl or woman, my respectful apologies. Onward!

Obviously everybody on here is not as helpful or bright.... :kali:

Thank's to those who did reply sensibly and on topic, I have re-formatted the card, and just shot 8 minutes without problem. And I now understand why it wont stop to 4 when zoomed in.

I'll post something on here when I can, oh, I did post my first shots, showing some 'artifacting' on reflected water: http://www.vimeo.com/5592620
 
Long time viewer, first time poster. I always check this forum for the latest GH1 news, but I just now registered.
Even though it seems like the problem's solved and it's a little late to respond, I thought I'd chime in, the error in Japanese says something roughly along the lines of: Due to insufficient write speeds for this card, recording has been stopped.

By the way, being of Japanese heritage, I actually don't mind if someone uses the shorter term for it, so long as there isn't any derogatory adjectives proceeding it. I can see how some might be sensitive to it though.

It's always a wise practice (and I consider it mandatory) to format the card by the camera. Even though AVCHD uses FAT32, and SDHC cards come formatted FAT32, the Panasonic manual clearly states for the HMC150 that you should (or, in fact, you must) format the card BY THE CAMERA. I have no idea how that changes anything, but it seems to.

So try formatting the card in the camera, and see if it helps your situation.
 
Formatting the card in the camera will probably help defragment the file system, so the GH1 can get on with the task of writing video to it.

I expect the GH1 has very little capacity left over while doing this, to bother rearranging files and the FAT32 database on the card to make way for large video files.

Thanks for the translation, I was wondering what the error was. Would you be so kind to translate one I have had as well?

These are usually nothing, but puts my mind at rest to know what my GH1 is trying to tell me :cheesy:

"Please check if your lens is secured correctly." or something to that effect.
Hope it gives you peace of mind, and keep them coming if you have anymore.
 
Thank you!

This confirms my suspicions, as I never got the error in any other mode apart from fully-auto where you cannot enable 'shoot without lens' in the menus.

Guess the lens and body contacts are still settling in. I have also noticed the lens release button is a little oversensitive and that can cause the same error.
 
I believe you can disable the requirement for the lens to be present. That way that error won't show up.

Indeed, but if there is a duff connection between lens and camera, you'd probably want to know about it (as the lens could then fail to communcate properly with the body, leading to unexpected results).
 
I know about the option to enable 'shoot without lens'... it's in my post above. But thanks anyway.

In auto mode you cannot disable the lens connection, the kit lens has to be present for iAuto mode. The problem has gone away now. I think it's to do with changes in temperature and a new camera. I have noticed it occur only when the temperature suddenly changes from cold to hot quickly, i.e. entering a hot building from outside, going to a summer gig with a busy crowd, going into cold air conditioned theatres, etc.

My other passion is fishing tackle. Some of the finest rods and reels are made in Japan for the Japanese Domestic Market. We "Tackle Junkies" refer to such prizes as "JDM".
