GH1 firmware research volunteers required

Got G1 body today :-)
Despite that we already own GF1, it is still stuck in USA.

I really do not understand Panasonic.
How they managed to lost market to Canon in Japan?

I suggest them to make m4/3 to Canon adapter with working AF and OS :-) and sell it for like $50. Same for Nikon and Sony lenses with build in motors.
It is not that hard as they think. And it brings you guys who afraid to switch.

Other option is to make AF adapter for manual lenses without AF (Pentax have such famous teelconverter thing).

I've been hoping for this for ALL lens manufacturers. There's no reason not to other than brand loyalty.

That'd be awesome to be able to use APS-C only third party glass, as wel. Sigma 30/1.4 comes to mind.

Hey,

Is it possible to create new picture profile settings allowing further tweaks on them? Mainly Im interested in lowering contrast and saturation as the -2 settings seem to not be enough and maybe this would give us a little bit more latitude.

Hey Tester13, did you note this? Do you think there's any chance for mods?

Thanks for the great work!

Yes, most glass is either Canon or Nikon compatible, but old Minolta glass is very good, as well as some Pentax glass.
If you really want it we need direct communication with camera division, with developers. As Barry noted such things happens in other divisions.
Writing petitions is pointless most of the time.
Direct feedback is the way to go.

Kholi, AFAIK 30 1.4 43'S fit with adapter

works on the m43's Olympus cams with af, eg EPL1-2, there is no reason why it shouldnt work on GH1 other than Panasonic havent added the f/w support. Also, I think it may be the case that they have added the legacy 43 glass support with af for the G2, will check it out for you. If they do a fw update to the G2 then tester13 may be able to see whats been done?

Are you saying that the Olympus cams can use Nikon and Canon glass? Or something else?

[PappasArts]

Just posted a few frame grabs shot real quick from the GH1's 1080P Hi- Bit rate MJPEG mode.

No, originally there was a 43's mount

This was the original Olympus mount and then I think Panasonic joined, hence we got the 14-50 leica 2.8-3.5, 25 1.4 etc all for 43's fit. There is a whole range of 43 lenses, incl. Sigma lenses, see list in compatability chart. Then when they release micro43, ie G1 then the EPL1 we got a new range of micro43 lenses and an adapter for legacy 43 glass. All of the Olympus cameras support legacy glass, but only a limited selection on the GH1 and GF1 and G1. Now, Pana has released the G2, avc lite but only 720p but guess what, they've added lots of legacy lense glass compatability. Not all the af functions work but for still single af is better than nothing and single af works in video too, to get you in the "zone". One of the lenses is the 30mm f1.4 you mentioned for 43's mount, if you add the 43's to micro 43's adapter you can use the Sigma now, but no af, but as I say the new G2 has AF!

And did you noticed my request for developers to make necessary tools?
Especially one to view and find all icons and images.
Without tools it'll be big waste of time.

No I didnt notice. Now I know.

Could an ".ini" file be provided for ptool so that when you run it, the last use setup appears? That might make it easier to tweak things from the last used settings. (Sorry if this is already provided for in some way but I've not seen it).

hi tester13

re tools for finding images in firmware

I used to program c on amigas in the 80s and have used c on AVR microcontrollers more recently, but for desktop stuff I've been using java for a long time - I imagine it should be possible to use java? I guess the only issue might be byte ordering (ie big endian versus little endian)

so . . . this tool would work it's way through the firmware looking for images
what format would the images be in?
it should be easy to search for a header for a gif, bmp or whatever

otherwise if they were just raw bitmaps you'd need to approach it differently

thanks for all the great work you and everyone else is doing
it's very exciting watching this all unfold

Citation from first page - First tool.
Small utility with good interface with ability to view firmware image and find icons and other images inside (visually showing images and offsets).

So, we need interface, not batch only utility.
As for usable instruments - I suggest to find free Turbo C++.
Or use Visual C++ Express if you are better in it.
Java is generally not good, as we need very fast redraws of large canvas areas.
If you are really serious (and won't be dropping development after few days) send me PM for all interface details and requirements.

Fantastic Work. It's incredible that such a leap forward can be acheived by one individual. Not only will it force panasonic to make the GH2 a much better camera than they probably wanted too, but it will hopefully give canon and nikon a kick up the backside too.

Feels like the revolution has finally begun.

Panasonic should see this effort as a very positive thing. Now they don't have to rush the release of the GH2 and have a terrible roll out like the GH1, and they should see GH1 sales go up significantly until then.

Perhaps Philip Bloom has some contacts at Panasonic that might support Tester13 with what he needs to make things even better?

...or maybe they should make him a job offer.

...or maybe they should make him a job offer.

I'm completely blown away with what Tester has achieved here, and in such a short amount of time. His skills as a hacker/programmer are formidable!

That being said, though, surely Panasonic has employees who could've done similar things, right? I don't think it's as much a question of there being one brilliant hacker who made the camera do things its creators had no idea it was capable of. I think it's a case of Panasonic simply hobbling the camera for one reason or another, maybe something as benign as wanting to maximize compatibility with consumer hardware devices, or allow the use of slow SD cards. Who knows...

I guess what I'm saying is I prefer having someone as talented as Tester13 on the outside of Panasonic, not the inside, because here he only has to answer to himself, not make some kind of distinction between "consumer," "prosumer," "professional," "broadcast," etc. It's as simple as the hardware being capable of so much more than it was being asked, and someone who was able to tap into that power.
