Tom, what I needed to do while shooting in HLG and avoiding that ‘RAW look’ while playing clips directly from the camera, was to up some of the HLG picture levels from their -5 positions. This brought the picture more in line with what you’d expect.

Obviously I need to do a lot more experimenting, this is all brand new to me.

Delkin V90 UHS-II SDXC cards are a POS


Quote:
Finally did the update. 2.0 rocks. Unfortunately, My Delkin v90 64gb has failed multiple times. Very frustrated. A handful of my Lexar cards have performed very well. Go figure. So confusing.
That was posted on the Facebook GH5 group page.

My three Lexar 2000x cards were purchased when they first came out and I now see there is a problem with the first batch in the GH5 V2.0 400Mbps 4K video. Lexar updated the 2000x cards with Rev E 64GB after that.





But I have yet to see the image quality difference in the new 4:2:2, 10-bit ALL-Intra 400 Mbps.

Quote:
I wanted to test the new firmware and specially it's new codecs. I'm testing the new 400 mbps and the new 6K codecs. There was some surprising discoveries, for the firmware update for the GH5 did give us some more details and more surprisingly better colour with the 6K.

This is the sharpest, most detailed video of the moon that i have ever seen.

I am sticking with 4K 60p and 6K photo in video mode ( plays in 8K 4320p & 5K 2880p on youtube) that has more than twice the pixels of 4K.

When shooting static images, quality won't benefit from higher bitrate intra-frame recording.

This is a new one for me i dont know if anyone else has had it happen,i ordered a new 12-35mm f2.8,it soon came,i opened the box and took the lens out and tried to put the hood on,fiddled a bit, it would not go on then realised the lens was not a 12-35mm but a 14-140 out of the 12-35s box,everything else in the box was for the 12-35mm lens,this is from a very reputable camera company and i believe them when they say this can happen,i have the replacement now.

Chris, that's really bizarre. I've never seen or heard of that happening. It somehow seems like a return that was put in the wrong box and never checked.

Ken with the lens & body caps on there is around 4mm difference in the length of the two lens,my supplier assured me it was not a used box,i just hope there will be enough times i need this lens.

I agree. I don't have the GH5 for it (yet!). But, I've had it on a GX7 and GX8 and enjoy it a lot.

The rest of my story is that I'm keeping myself to two lenses to maximize mobility and still get range. The other one is the Panasonic 100-400.

Bill, I agree about keeping the weight and size down for my gear. I don't like schlepping big & heavy gear, even for a day, so I too use only 2 lenses. My other lens is a 15mm Lumix 1.7, used only for low light situations and it's almost weightless.

In all honesty, I find the GH5 to be good enough in low light, that switching to the 1.7 is a rare occurrence.

The main reason for me not getting the 14-140 is because I use my RX10 III for wide zoom ranges and I have the Leica 8-18mm F2.8-4 , 14-45mm , 14-42mm , 40-150mm, 100-300mm MFT zooms along with 25mm F0.95, 42.5mm F1.2, 75mm F1.8 primes.

Joe,

You have too much gear!! If I had all that I would always be switching from one to another and never getting anything done.

The one piece I am jealous of is the Leica 8-18.

Bill, my Leica DG Nocticron 42.5mm F1.2 just had a new V1.3 firmware upgrade to Dual I.S.2 so that and my 8-18 Leica are my two favorite most used MFT lenses. BTW I also use a myriad of Pentax and Nikon mount DSLR lenses with MFT adapters along with my scopes.

European vacations are fun, and ship cruises too. The video is enjoyable, I give it a "like" but I have to agree with your question about anyone caring for standard mode anymore because it really showcases the GH5 at it's worst, 60p as well. I just didn't think the low light noise and blown highlights could get any worse than the Dragon Cave video, but they did as soon as you were shooting from inside the bus where the daylight interior was crushed into dark while looking outside the blown out windows. I do realize you are under time constraints, shooting on the move among crowds and trust heavily on the automatic features, white balance, focus, exposure. And in many cases they were very nice, especially where there was ample light. But where there was not; purple water in the caves, macro blocking noise and grain, blown out highlights obliterating detail. It's understood not everything we shoot comes out perfect. And on a vacation video you're wanting to preserve all the sights and memories so you include everything in the final cut, even the poorly lit. So I get it.

But consider if you had used a fast 25mm f1.2 prime, you would have had the normal field of view which is usually not very far from ideal for most general shots. Shooting at 24-30 fps you could have had available 4-1/3 more stops of signal to noise (from an f4.0), then with V-Log-L would have gained 5 more on top to preserve the highlights, all without adding any gain. Shooting 60p came with a hefty penalty in image quality for the majority of the shots; static, not too much high speed action and conceding filmic character and low light sensitivity. There is a reason why travel magazine shows are shot at lower frame rates. But I like it. Thanks for posting.

Thanks for watching and commenting. There were several factors besides those you mentioned that contributed to a loss of quality.
1. Several times I forgot that I had the ISO set at 6400 and shot in the bright light at that setting.
2. I have extremely poor ability to hold this camera in any way steady when shooting. Thus I end up using the tripoid mode in stabilization with Final Cut.
3. As you mentioned, too often backlight presented adverse shooting conditions.
4. The cave was so dark and extremely crowded, so I could not find and adjust settings on the camera.
Maybe should go back to my Sony AX-100.

You mentioned shooting at 60p as a minus. Why do you say that?

Thank you for receiving my critiique in the helpful spirit intended. You're hand holding was fine, nice job! About the 60p, I own some personal bias against the look in general but my comment in your case was directed to the opportunity lost to gain a full f-stop of light gathering in the cave by dropping the shutter speed to 1/30th, the scenes were pretty static so motion blur and handholding would not have been a problem, your shots were wide. One of the lower contrast styles, natural for example could have brought the lights and darks closer together. We like a camera with high contrast potential to help differentiate in flat light, but don't want excessive contrast in light that is already contrasty. A 3x ND filter is part of your kit in bright light to allow slower shutter speeds for natural motion blur just like your AX100. In a perfect situation I would have planned the cave shots to shoot wide open or nearly so with a fast prime, 1/30 shutter, the lowest possible ISO, VLogL or Natural, NR bumped up, maybe all the way to +5. (In good light I would go the other direction with it.) Lastly I would trust my reading of the waveform monitor not the image, to look for and avoid compression of the highlights and shadows, making a judgement in favor of the most acceptable compromise, because there isn't enough in-cam DR for a really high DR scene that a dark cave with artificial lighting represents. No need to go back to the AX100 based on this experience. You're on a mission to learn, and a GH5 presents opportunities to explore great imaging features including DR, sensitivity, bit depth, bit rate, log gammas and wide color gamuts. Your videos I am confident in saying would not have been better with the AX100, were well composed and shot, your editing very nice. Build on the positve. Nice work!

I was told from a reliable source to expect the announcement at any time about a new mirrorless, video-centric camera from Panasonic said to be a low light "monster" in the vein of the A7SII. The new camera would use an "organic" light sensor patented by Toshiba, co-developed between Fuji and Panasonic. The organic sensor is 3 times more sensitivity and with more DR as the sensitivity of each pixel is controlled, not just in blocks. Instead of using a cmos photodiode, the organic sensor uses a nanometers thin plastic conductive layer that is sprayed on with the transistors and capacitors, and is 100% light transmissive. Every part of every single pixel, including the electronics, is sprayed with the liquid polymer solution, giving a surface that is 100 percent light-sensitive.

This is nothing short of groundbreaking if the architecture of the new chip is as you describe. The differences are far more drastic than CMOS and CCD.

I wouldn't underestimate Toshiba, though. They developed a first rate sensor for some Nikon's DSLRs early in the 2000's and made the landmark 41M-pixel, 1/1.2" CMOS exclusively for Nokia 808 PureView symbian phone. That technological achievement was quite phenomenal. It allowed Nokia to incorporate new very useful features otherwise impossible with all the other cameras/sensors in those days. Everything else in that phone has died the way of the dinosaurs except for the camera and the sensor. The stills image from which can still compete with those from today's flagship phones.

If this new organic sensor technology can yield truly better results, rather than the jargons and the impressive numbers and these results can be made trickle down to cameras the majority of the consumers can afford then it would be another groundbreaking achievement.

Imagine doing away with log gamma or high gain noise. Just point the camera, set a correct exposure and focus and shoot the same way Nokia PureView users blissfully and electronically zoom into the subject at up to 3x magnification with a tiny single focal length lens with 5M pixels left to spare.

If this sensor is ‘co-developed’ by Fuji and Panasonic, how does Toshiba wind up with the patent?

Either way, just when Panasonic had reached new heights with the GH5/v2.0, along comes the possibility of this video-centric monster with what may be unprecedented low light capabilities.

I suspect it’s too soon for a GH6, so might this be a camcorder or something outside of the GH line?

The source said it's a mirrorless cam with video centric features to co-exist in the niche similar as a7sII was to a7rII. Also said it would use 12mp, not the oversampled 20.3mp of the GH5 which rules out the 5k.
