But P40 vs P30 pro 5x : quite the same :)

Kaloyan, 16 Apr 2020Hey, sorry for misleading you. Tested this again very caref... moreSo P40 Pro series CAN actually shoot at 23mm equiv. field of view without any problem, but crops in by default? That sounds interesting but also must be frustrating at the same time. Probably they do that to bridge the gap between UWA and the main cameras and prevent the quality loss, but they should've still made full use of the wider angle lens for the main camera at 1x magnification nonetheless.

Anyway I really appreciate your additional information, you should probably update the review to reflect your finding.

Tested this again very carefully on the P40, indeed outzooming until 0.8x uses the main camera and you can actually get the full field of view. The corners are a bit soft though - maybe one of the reasons for the crop.

"you can indeed notice that the high-res photos offer wider field-of-view, meaning some cropping is happening before we get those 12-megapixel photos"
Gsmarena, show us some sample images at 23mm in the low resolution mode (should be at approximately 0.85x) , it would be interesting whether it uses the full field of view of the main camera or whether it crops the ultra wide angle camera

good thing Huawei did a big price cut for this in our country. they're selling this for about $720.

About the 5x hybrid zoom, GSMA, you write "Sure, those aren't a match in detail to a real 5x tele, but quite close".
Well when I compare the details and textures of the P40 review pics with the P30 pro review pics (for instance the snail), I hardly see a difference! Somehow the P40 5x hybrid produces the same quality as the P30 pro 5x optical zoom.

Anonymous, 10 Apr 2020"Also the stutter in frame in extreme low light in the comp... moreRYYB sensor calculates green value from the amount of light entered to yellow pixels and red pixels, which means it actually produces more chroma noise than regular RGGB sensor (because this kind of colour interpolation processes always introduce more noise to the image) and its colour accuracy suffers quite a bit. The camera can handle those issues well when taking still photos because it can sample colours information from multiple images shot at different exposures, but obviously it's impossible to do that on video. This is why you start to see a lot of colour blotches in sky under very poor lightings when you're shooting a video with the main camera - interpolations simply don't work that well when there's barely any light entering red pixels even if yellow pixels are letting in more light into themselves - and Huawei recommends users to use Cine Lens instead. And yes auto frame rate can be turned off by switching to 30fps or 60fps.

'Cine Lens' for videos which we all know already has a smaller Fov compared to other flagships"
..You mean compared to other flagships' UWA cameras that drop significantly in quality in low light? And could you give me a link to a video that shows P40 Pro's captures narrower field of view than others during video recording? Because I couldn't find one on YT.
And as I already said, many phones from competing brands don't give you an option to turn off EIS, so I don't see how it can even be a problem for most people, even though I admit it's a nice feature to have nonetheless.

To be honest, not really. In some cases S20 Ultra wins, in others it goes to P40 Pro. This "artifacts" problem won't show up under regular lighting and it's not something that will bother you unless you're shooting videos in pitch black.

If u rly want that jack , then u can use adapter jack to aux and problem solved.

Why not increase the battery capacity or at least keep the 3.5 phonejack in a budget oriented variant, I will never understand.

Can you explain why RYYB filter is not very suitable for video recording? Coz most of the footage comes out soft especially in low light compared to other flagships.

Also the auto frame rate adjustment sucks. Had it on previous HTC and LG flagships back in the day. Only Samsung used to give proper stable framerates even in low light.
Are you telling me there is no way to turn it off? No way to get solid 30/60fps footage without lowering frame-rate in low light? Do third party apps like Lumio cam help lock footage to a specific frame rate without drops?

You do realize that stabilization turned on reduces Fov? Since there is no way to turn it off, you are stuck with it. Also Huawei by default is resorting to the 'Cine Lens' for videos which we all know already has a smaller Fov compared to other flagships.
Look at the S20 footage in low light(with hybrid stabilization on) and compare it to Huawei, you'll notice difference in quality. Also remember how the default bitrate for videos, 4k or otherwise is lower compared to other flagships. Maybe that's the reason for those artifacts in low light.

Because the footage is so dark on those phones that there isn't anything much to show in the first place. In regular low light P40 Pro's video doesn't show any artifacts, apart from bouncy light sources that are common phenomenon among most Android smartphones. Also the stutter in frame in extreme low light in the comparison you linked is most likely due to the RYYB filter not being very suitable for video recording and auto frame rate adjustment that newer Huawei flagships have on by default.

"combination of AI with EIS/OIS"
...which is essentially the same as hybrid stabilisation that other companies frequently use, but with EIS bit being assisted with NPU. I don't know why you think it is the cause of the artifacts when there are clearly more important factors that should be taken into account.
