GH4 GH4 firmware 2.0 released

Both my GH4s are already updated. Running camera test on them tomorrow against an Amira, & F5 for motion, plus the D800 & 5D3 for stills.

Likely cannot share any images.
 
I have 2 GH4s so will definitely do a side-by-side test before upgrading both.

Any hints on reproducing the possible noise issue, exactly? What picture settings were you in?

Very cool we have new aspect ratios! Yaay!

Just upgraded one of my gh4 and compared the speed between two (menu wise and such), they are the same, there is also no difference on lag when go to an external monitor, also, the noise is the same. I used the same camera doing a before/After with the same lens and same iso...

They could have changed the way noise reduction works, so that might be worth testing, too.
Good point. Maybe zero means truly zero and noise reduction is applied only when you chose from +1 to +5. But then, what happens when you chose below? Noise is artificially added? ;)
 
I shot a before and after 4K UHD 30p at 800 iso. I can't see a difference on my 27" 2.5k monitor. Firmware v1.0 showed 79mbps. Firmware v2.0 showed 93mbps. There surely isn't any more noise.

Cheers,

I wonder if this will affect which cards work reliably. I have been getting away with uhs1 95mbps cards in uhd. If the bitrate is higher now I might need uhs3...

I've been shooting on U1 Class 10 Sandisk 95MB/s Extreme Pro 32 gig cards and haven't seen an issue with it.

Much thanks to everyone who has done a before/after comparison regarding noise. Very reassuring that there is no difference.

Can someone confirm there is less strobing when shooting in 24p/25p? (except when in Creative Mode or 30p)
I returned my GH4 because of that so it would be great if they fixed that issue... :laugh:
 
FINALLY!
When using 4k photo mode, at NR -5 definitely no noise reduction is applied, no more strange motion blur at ISO800 and above!
The resulting video looks much more like raw video, less processed.
 
any word when the US page will have the update?

Any reason you are waiting for the US page ?

I upgraded my Canadian bought GH4 camera using the Panasonic Japan firmware link with no problems. My GH4 menus remained in English and I don't have any 30 minute limit on the length of videos that I can shoot, so I don't see any issue with using the Japanese website.

What about the supposedly improved autofocus?

This sounds very positive! Thanks for the info.
 
Hmmm.. just updated my GH4 and now the Wheel near the ISO button no longer controls the ISO, it used to before... the wheel nearest the on/off switch controls it now.

Camera seems slower to start up than before (had always been impressed with the boot time, but it definitely seems slower)

Noise / high-iso ghosting is still present for me.

If I were you guys I would wait until someone does some side by side tests of this firmware and the previous one.
 
From what I read, when you press the ISO button and the screen comes up, look over to the lower right and you'll see a choice of which dial controls ISO - touch the front wheel or the back wheel on screen graphic to assign. This has to do with the new feature for accessing upper ISO's.
