Yes it seems like cropped and enlarged to full size.

Stefan66: What will that sensor tech mean for the rest of the camera industry? Will it be possible to make a M43 camera with ISO 800 000? Will camerasensor-size just end up being a factor for depth of field in the future?

You apparently have not try it. It is stacked technology perfected to unbelievable results. Not perfect for sure - but unimaginable for devices of this type. And I am not reading marketing BS - I have it right now in my hands.

vadims: Few words to people hellbent on dismissing that ISO 400k claim.

As a rule of thumb, one can say that "last usable ISO" is usually last but one available (e.g. ISO 25,600 and not ISO 51,200 is the highest I ever bother to shoot w/my a6500 even in "emergency"). Yes, there are exceptions, but it's true for the majority of cameras. It's that very last, highest ISO value that is "marketing ISO".

Previous generation of Huawei phones with their flagship cameras, Mate 20 Pro and Mate 20X, went up to ISO 102,400. Was ISO 51,200 a gimmick? Let's see:
https://petapixel.com/assets/uploads/2018/03/huawei-p20-pro-high-iso-example1-original.jpg

Left is ISO 1,250, right is ISO 51,200 of the P20 Pro. Well, you might be someone who shoots nothing but ads for Nike and spreads for Vogue, and see no value in this. But for us ordinary people, ISO 51k in *previous* generation of Huawei's phones is very usable.

As to P30's ISO 409,600, jury is still out, but to just blindly dismiss it is kind of dumb.

Yes HighIso improvement is clearly visible. I compared P30P with P20P (have them both) this afternoon and where ISO 51200 was still usable now it is app. 2 stops higher. Even in complete darkness where it was nearly impossible to frame correctly (better said to see anything) image came out reasonably well. This is a first hand experience not somebody hears that somebody else claims etc...

In reply to:

iken30: Its really strange the image quality on the LG G7 is so bad compared to previous G and V series, I´v had the LG G4, G5, G6 and V30, all of them much better than the G7. Whats most strange is it shares the same sensor and hardware as the much better LG V30 although I'm not sure the lens is the same (V30 is glass, don't know about the G7)

I did a mistake buying the LG G7 before professional reviews commented about the image quality, in fact there are only 3 sites (preview, dxomark and gsmarena) that do good reviews, other reviewers don't post full size images and I'm not even sure if they themselves check the images at full size before commenting on the image quality.

I had to return my G7 with 10% value loss as the camera was so bad, returning to my V30 which is much better.

Soon LG will release their V40, claimed to be 20MP on main camera, I really hope this time they put more serious attention to the camera. They need to improve both hardware and software.

Exactly G4 and V10 were last phones where obssessive NR and watercoloring did not occur. From G5 on - I am just wondering - whom they want to appeal? I do not think phone is the right device for pixel peeping but this level of IQ?? Come on LG wake-up.

Jefftan: "Debayering – The algorithms have been improved to increase the amount of micro detail while reducing aliasing, yielding photos that are noticeably crisper with less color artifacts."

if true is great
detail extraction should be the most easy to test (and compare with other software or previous version)

However the core rendering is plain ugly with High ISO. It is so coarse compared to anything (RAWtherapee, Topaz Studio, DXO, Cyberlink Photostudio, Silkypix, LR). Using with M43 above 3200 is disaster. Noise reduction is still pathetic. They should probably add different de-bayering algorithms to choose from (aka RAW Therapee). From ON10 through ON12017 up to now rendering was problem all the time - however with latest release I am really disappointed. Everything else is more or less OK - but you have to start debayering somewhere else.

In reply to:

Mastering Light: Can someone with a GH5s test continuous AF with a sub 180 degree shutter? Like 1/50th and 30p? (24p may not work). For some reason C-AF becomes much improved when using less than a 180 degree shutter. This was a recent finding and is getting discussed on video sites.
It appears to be superb at 25p yet poor at 24p with the GH5.

GH5 - It seems that improvement is only for 25/30p. Not 24p and 50/60p. Tried with my several native lenses (50/60p) and there is no difference to speak about.

In reply to:

Androole: It's a real shame that LG has decided that marketing the lens is more important than specifying a proper sensor.

Since the LG G4, the main camera specification has gotten progressively worse. The LG G4 had a very good sensor, and was arguably the best camera phone on the market during its availability. The same can definitely not be said of the G5, G6, and V30.

V10 was even slightly better (I have both G4&V10) but then - totally agree - they went downhill.

I am totally disguisted with this new generation cameras quality. It started with G5 continued with G6 V20 all through Leicas Huawei Mate 10PRO and likes. That oversharpening and total denoising is just ugly. Typical smartphone as most of us knew and probaly hate from the past. I have LG V10 my wife LG G4 and there is no comparison in detail, crispness, fine textures definition (leafes, grass etc.). RAW from V30 is comparable with JPG from V10 - but not completely. I would like to change my V10 for something newer however not this picture mess. No thanks.

In reply to:

KrisAK: Seems like the G9 might exceed the video capabilities of the GH5 in a few key areas, in particular DFD/AF. (Or not, as the case may be.)

I'd love to see a detailed comparison in terms of video capabilities.

This just won´t happen. Panny is not stupid. Sad truth is that my most beloved feature 4k/60fps is crippled to 10mins. only. And within this price bracket it has not be considered as video recorder (EU) thus limited in any mode to 30min max.

In reply to:

(unknown member): Which Panasonic lenses are required for DFD and 6.5 stops of stabilization?

Only explicitly mentioned lend is 14-140 mkII - i.e. dual ibis 2. G9 will be probably tweaked in some aspects however those 6.5 stops (with 14-140 past 100mm) can be achieved with GH5 easily.

Croninfilm: Perfect upgrade to my G85. Been craving 4K@60p/HD@180. The Gh5 has too many features I wouldn't need, this sits nicely between the two. (I'm primarily a video shooter)

And for all you M4/3 haters out there...its really all about the lenses. If you consider the fact that most camcorders have 1" sensors or smaller, the M4/3 system for video really is a nice sensor size for event and commercial work. The ISO capability really has increased over the last few years. Lumix for Life!

If you are primarily video shooter then beware of 10min limit for 4k/60fps and 30 min limit overall in EU

Why underexposing by -0,66 EV? You have zebras you have histogram. This is not a DSLR where you just guess the correct exposure

Out of focus areas are rendered quite poorly (lower third of frame). It reminds me of some OLY PRO lenses (e.g. 40-150). Was expecting more smoothness.

It is hard to mimic GH5/G9 JPG rendering with RAW (e.g. smoothness without loosing detail). This is a clear example.

I am quite surprised by low quality rendering - water color quite often especially in greens. Having V10 and G4 I hardly ever got this level of smearing. I think LG with this model has gone Samsung route - quite heavily overprocessing the JPG. V10 renders - at least in comparable scenes - visibly more naturally - not to mention available full manual video mode.

MarioV: Looking at the studio scene comparisons, the Lumia 950 matches or outperforms all other phones.

However real world samples (especially people and skins) are not all that positive

Not that bad at all. However skin tones are nightmare not only with flash. And HDR no matter how many options you have does not made it for me. LG´s HDR is just beautifull. However front camera delivers!!
I also agree with POTATO about usability of 4:3. Most people are looking the pictures either on TV, PC or phone/tablet. And all monitors around me are widescreen. Watching 4:3 on widescreen is throwing away big part of your screen (black borders)
