Now that OP has changed the title, it's become irrelevant. Before he kills me ... I meant the pictures you get when the sensor is pushed to its limit in low-light. It's not a standard term, btw lol

Some extreme examples

At the very extreme end, Xperia outputs will wash out. But couple stops before that Xperia will get you a usable output while the others will still remain pitch-black. Try it out when you get a chance.

I will do it (without a tripod - you kidding right). I live downtown & I got tired of taking night shots long time ago. Next weekend - hopefully.

[Xperia Z5 General] TheEndHK:
Here is my indoor(metro) and night shot(outdoor) campaign of S6 vs. Z5c. All are shared in it's original size without editing other than renaming.

S6:

FHD - Software stabilization disabled, OIS enabled(can't be disable)

UHD - OIS enabled(can't be disable)

Z5c:

FHD - IA software stabilization on

UHD - Standard steadyshot on

All photo and video were shot by stock camera handheld. Sony only allowed to pack ISO in 8MP Manual so all are in 8MP from 100iso to 3200iso, skipped testing 50iso bcoz 100iso already super easy to create handshake. S6 were all from Pro mode(standard auto mode can't select ISO) range from 100iso to 800iso, max is 800 from Samsung offered, can't go higher in Pro mode though sometimes the auto mode could boost up to 1000ISO.

Some photo got little handshake and I've no time to just keep repeat shooting. In my experiences, S6 easily beats Z5c in terms of handshake and focus performance(at very low light S6 focus is superior, more faster and accurate). Indeed, many photo from Z5c been shot for a couple of times to try to get best result and almost all S6 photo were just taken in one shot(no more than two).

S6 got very good quality of video as well as photo, I think the OIS is quite helpful for the video part too. I'll probably add Z5c/S6 fast walking video today or tomorrow when I've free time to do more testing.

Z5c link: https://drive.google.com/folderview?id=0B4Nx7PgyQVgJYjdOcEJPUHJORjQ&usp=sharing

My Z5c is bootloader locked with DRM key so it's still with the low-light denoise algorithm. I may unlock it soon. My S6 with ISOCell, not Sony IMX240 sensor.
[Xperia Z5 General] bloodfire1004:
Thanks for this! I'm sure many appreciate the efforts :)

Though I'm not sure if its just me, but honestly, I prefer the pics from the Z5. For me, the colors / the overall photo itself looks "natural" or more "realistic". Of course, I do not know the actual colors / conditions of what it really looked like but the colors of the S6 seem to be too artificial (and more orangey / redder tint to most of them).

Just my 2 cents though.
[Xperia Z5 General] TheEndHK:
You'll need to download all stuffs and check it out on a big PC screen. S6 color can be more better because the default is over. I always preset lower one stepping of saturation and color temp in Pro mode but this time I just let it run default so the result got worse.

If you check the threads on this board, I've said it a dozen times that Sony got better color(my taste) and that is why I buy the Z5c while I already own a S6. In fact, S6 is over whilst Z5c color is also a bit off(under/lower) but just more close to the real scene.

Speaking to the details part, S6 just win hands down without any doubt.
[Xperia Z5 General] EQ2000:
The histogram shows the Z5 is more accurate. Viewed a couple of the photos and resizing the S6 photos to match the res and aspect ratio of the Z5c (2448x3264) show the Z5c often delivers more detail but also a bit more 'fine' grain vs blurrier and noiser (noise blurred out but still visible as blotches) S6 photos (depending on ISO level). Also several photos have a photo (PhotoME exif reader) time date with a difference of 15-20 minutes between each camera and same shooting location..

Here is a crop from both at 2448x3264 and with aspect ratio correction. This is from the S6/Z5 ISO 800 comparision. Top is S6, bottom is Z5c. Photo crops from HKs comparision.
[Xperia Z5 General] TheEndHK:
Excuse me Sir. Do you actually know what are you speaking? You always blame S6 got strong noise reduction but when you found noises there you also said that S6 is too bad to has noise.

Sony is all good in your mind even there are indeed more flat area in photo but you'll just think that some noises to simulate fine grain so it's all good.....

To be honest, I've also played a lots of video stuffs, I was a video lover. The film grain isn't real using in this way. In the old days video encoding technologies were not yet mature, the encoder did remove too much things from the source and people was trying to apply some noises in flat area to fraud human eye but this method should not use again in recent year. Some others were trying to simulate old Film noises for special purpose though.

The environment is total stable and it won't change the result after 15 - 20mins like day time so it is meaningless to mention about this, I'm not only focusing to take photo because my friends whatsapp me. Furthermore, the Z5c is freaking hard to get good result in such low light condition, some scenes were actually been taken 4 to 5 times to try to get one with good result. S6 was almost all done in one shot.
[Xperia Z5 General] Timaustin2000:
While an instructive and very interesting comparison, we do loose a bit of something by dealing with differing Fields of View. Some of the loss of detailing that you might otherwise put down to the sensor or software is actually far more about the focus of the lens on the sensor. To see what the detail reproduction is more accurately, we could do with seeing the two framed identically (IE, taking half a step nearer with the Z5 when taking the shot to correct for the different lens).

While I hate to put you to more trouble, could you have a go at this at all? Thanks :)
[Xperia Z5 General] joe_dude:
Ah, Hong Kong... been there several times. Sorry, but I hate to say it, the video quality on the S6 was not very good. Maybe when standing still it's good, but as soon as you started panning, the video was jittery. In FHD, the Z5 was completely smooth. In 4K, both videos were jittery.

If you're going to critical of the Z5, you should be at least as critical about the S6's poor video performance. You live in HK... a fast paced city. Hold it up and walk around with the crowd, take it on the bus, go up and down the subways stairs. Don't use the Z5 and take video like it's an S6 - judge it on its own merit. If you've ever tried to keep up with a child and record video, you'd know what I mean!

Thanks for the vids and photos... I'll check out the photos later.
[Xperia Z5 General] joe_dude:
Okay, I've gone through the pics, comparing both sets of pics side-by-side. First thing I noted was that a few of the Z5 pics were actually less blurry than the S6. LOL! I think I could have done better with the G4.

At 100% size, the Z5 and S6 had nearly the same level of detail across the pics, except for a few pics where either the S6 or Z5 was clearly blurred. The Z5 had smaller text because of the FOV, but it wasn't any harder to read.

I thought the S6 would be the clear winner with OIS, but the pics look very close in quality. Z5 should have slightly better colours, but I can't tell without neutral reference pics. I think you should have spent more time stabilizing the S6. From your pics and video, I'd choose the Z5, since the only thing that's clearly better from the two sets was the Z5's FHD video. xD
[Xperia Z5 General] joe_dude:
Now that I've had the Z5 for a couple of weeks, here are my thoughts:

Here on XDA, we tend to get overly technical (no, really?), so I've been thinking about how a "normal" person would decide to get and use the Z5. I bought the Z5 based on early impressions of its video performance and technical details of the new camera system (dat closed-loop actuator). After taking some family vids running around the house, I'd say it works as advertised.

But it was my SO's reaction (a non-geek) that was more telling. She was curious how the videos would turn out, as I barely paid attention to the phone while it was taking videos. She was impressed and commented that it was so smooth that it looked "professional". As any family man knows, having the "other half" onboard with a tech purchase means life is good! Heh!

The photo quality? Frankly, she didn't notice much difference between the Z5, G4 or even my old Z Ultra. The G4's OIS didn't help much for impromptu pics of people. I had plenty of blurred indoor shots of moving faces with each phone. The Z5 did try harder with face detection and scene selection to get good pics, while the G4 was basically a straight dummy point-and-shoot. The G4's strength is in its manual mode, and in quick snap situations, there was no time to play with the settings. Ironically, I caught some of the best moments - not talking about colour or details - from the Z Ultra, as it was the camera I was most familiar with. LOL!

The Z5 is now my go-to camera for videos. I think anyone who wants to take good family or vacation videos (or even vloggers), the Z5 is probably the best choice for a phone. Personally, I'd still take a real camera on vacations for better pics and optical zoom. Gawd, nothing is more annoying than taking a pic of something and have it show up the size of a pinhead because I couldn't zoom in.

:mad:
[Xperia Z5 General] schecter7:
Fulfilling half of my pledge. Other phone died & bartender didn't serve me tripod or OIS this evening. So SA w/o tripod all the way.

[Xperia Z5 General] Timaustin2000:
Good shots and a good example piece that demonstrates that you can get very good night shots from the Z5. I especially like the carriage.

As is my way, I've been looking through Flickr at S6 shots that random people have posted and have come across images like https://flic.kr/p/A14UVf and https://flic.kr/p/ytEfJq - both of which are noisier than a great many night shots and indoors night shots I've taken with my Z5. These are not isolated examples.

Not very scientific, I know, but it's evidence that getting good results is as much about the person behind the camera as it is about the camera itself. Those S6 shots aren't really any better than anything that the Z5 could produce: detail is relatively similar (though a little better with the S6, probably) and noise is higher. Compare that bar shot with one of mine in MUCH worse lighting (so much darker than the image produced): https://flic.kr/p/AHaxNj . Sure, the detail is smudgy but it is there and there is far less noise, to boot. Not saying that my image is perfect - anything but - but seeing the S6 bar shot above (Full of very ugly noise in an environment with many more light sources) makes me wonder just how much better the S6 would've handled that scene, if at all.
[Xperia Z5 General] doministry:
Some of my initial comparative shots.

Just my first day with Z5, and the shots are in difficult conditions sometimes, on purpose.

The Zoom is ok considering it was bad lighting.

https://flic.kr/s/aHsknZUGYc
[Xperia Z5 General] joe_dude:
schecter, those are some nice night shots. Looks like you live in an interesting part of town...! How did you find it stabilizing the camera? Had to take a lot of shots?
[Xperia Z5 General] joe_dude:
From TheEndHK pics, I'd say the Z5 and S6/Note 5 (same camera, right?) are pretty close in low light. We're talking a very small difference in sensor size, so it stands to reason that they'd all have pretty similar (mediocre) low light performance. The super-sampling does clean up noise pretty well. And colours do seem to favour the Z5.

Compared to the G4, I did have to be more careful with the Z5 for long exposure times. I've learned (even with OIS), it's best to take a few pics in rapid succession in low light settings. I also didn't realize at first how much I was swaying while standing. Simply sitting down or leaning against something increased the level of detail. I had thought it was hand jitter...!
[Xperia Z5 General] schecter7:
[MENTION=5126759]Timaustin2000[/MENTION] Thanks :) As they say the camera is only as good the person behind it. Besides, we compare lemons to watermelons & complain about lemon details :p Your album is amazing ! I'm a semi-decent shooter & I don't think anyone would have any problem with Z5's night shots.

Thanks :) I did have to re-take some shots. Z5_00 for example as I had to hold it up in the air, also few others that came out better but got ruined by human & car blurs. So I actually uploaded the first shots from those scenes. SA intelligently picked 'document' in the text-heavy situation here couple times :p ((which I interpret as high ISO warning in this kind of cases lol) , so had to take it in a rush after jerking it around a bit. It could have been better. I didn't find stabilizing the camera challenging at all. Please keep in mind all these are SA non-tp mode as you proly could tell from high-ish ISOs. They could have been better in SA tp mode (which I couldn't do at the first go most of the times as I told you earlier), but I just wanted to see how SA does without it. Also check this one out. I literally had a second to take it as I was running across the street. It still picked up those texts from the first sign on the right. I like SA much better than before (when I did that indoor comparison). It's very capable even in non-tp mode, just don't rush it! Oh I did long for a wider FoV :p in front of the capitol building (& two of my favorite skyscrapers that I passed on). Have some quick burritos (from two different evenings) :p
[Xperia Z5 General] joe_dude:
Update the conclusion, but nothing important. Carry on, carry on. ;)
[Xperia Z5 General] dandv:
I performed a similar test, photographing a high-detail scene in a store (moderately low light). The camera with the best detail clarity was, to my surprised, the inexpensive Nexus 5X. The labels are sharper than on the Z5, iPhone 5s, and Galazy S5.

Full-res detail comparison photos are on Flickr: https://www.flickr.com/photos/danvdascalescu/albums/72157662379516921. Below is the Z5 - not impressed.

[IMG="Z5 detail photo"]https://c2.staticflickr.com/6/5774/23817374295_90abf9c526_h.jpg[/IMG]
[Xperia Z5 General] EQ2000:
Z5 is the best one there without doubt. Looks the most natural while being able to capture more light with lower ISO. the Nexus 5X is almost an eye-bleeder with the excessive post-processing. S5 is horrible, looks like it got "bloom effect" on it where the whites glow giving it a dreamy look. Dont remember it was so bad when I used an S5 at similar ISO and fluorescent lit scene. Maybe a bit dirty lens cover?

Both Z5 and Nexus 5X shows edge warping. Iphone 5S is by far the worst with tons of noise and loss of detail by noise reduction. Summary is the Z5 is best by quite a some margin. The rest inbetween and last the 5S.
[Xperia Z5 General] frankm87:
[MENTION=6922850]EQ2000[/MENTION], can you highlight the relevant part of the pictures? Maybe I am missing your point here. I am no photographer, but I looked quite hard. The only thing that is striking me here are the blurry edges of the Z5 (mostly due to the wide-angle lens, although it is clear the lens seems a bit off-centered to the right side).

The Z5 colors do look good, but so are most of the other shoots (the 5S is the less good, admittedly).
[Xperia Z5 General] rajkant1984:
Could you please tell me about the blurry edges in the following pictures.

https://flic.kr/p/Cnk5s7

https://flic.kr/p/CehEP4
[Xperia Z5 General] frankm87:
I do not see anything wrong here.

On [MENTION=326772]dandv[/MENTION] 's pictures, I do see a lot of blur on the edges. It is a bit annoying. My point was, if we forget the blurry edges, can [MENTION=6922850]EQ2000[/MENTION] point to picture details showing off the Z5 superior quality?
[Xperia Z5 General] EQ2000:
Look at the contours of objects, the contrast transition, how sharpening affects the halo, local contrast use/unsharp mask radius, white balance, clarity, material color reproduction, dynamic range. Look at them in Flickr "fullsize" (2048x1536) else download the original and downscale to lowest common denominator (either 8MP to compare to 5S or 12MP to compare to 5X). Use lanczos, bicubic sharpen or smooth downscale algorithm. Comparing a 12MP vs 23MP at 100% for the later to look as clear or better would mean it is by far superior as it 'zooms' in a lot more.

Also when comparing photos on the computer use something like Photoshop, Lightroom, PhotoFiltre and not the windows photo viewer. The windows photo viewer applies "smart sharpening" and alters colors. 9 out 10 times it makes the photo look worse (often a lot worse for monitors as it is designed for TV screens and viewing distance of 2-3 meters or more) just like the Sony Xperia X-reality feature that you thankfully can disable.

[Xperia Z5 General] Jonathan-H:
Yep sure have.

For me, the manual controls of the G4 along with OIS means with some fiddling you get much better shots on the G4 in low light thanks to being able to lengthen exposure time and leave ISO very low, bringing no noise and sharp images.

With the Z5 you have to boost the ISO to silly levels and you get a photo of mush.

In auto though and in most conditions I think the Xperia gives a more useable shot with less motion blur.
[Xperia Z5 General] doministry:
Apparent on 23mpx auto mode.

NEVER happened on any Auto 8mpx NOR Manual mode shots.
[Xperia Z5 General] doministry:
These shots in a very difficult lowlight.

ISO 3200
[Xperia Z5 General] EQ2000:
Good luck using long exposures where things are moving like crowds, cities etc. Long exposure is only realistic for static scenes hence higher ISO is a necessarity. And the Z1+ line just beats the G4 with ease in high ISO and delivers relatively good quality at such ISO numbers. You also dont need to manually process the photos afterwards to reduce the chroma noise that plagues G4 photos in low light environments and hence why G4 has more finegrain detail as there is always a detail loss when removing chroma noise especially on mobiles which cant employ heavy noise reduction algorithms unless one wants to wait for minutes for each photo to be done.
[Xperia Z5 General] frankm87:
I checked the photos located at https://www.flickr.com/photos/danvdascalescu/albums/72157662379516921

The Z5 does look better than the S5 when looking carefully. The vivid colors of the Z5 are better. The Nexus 5X is good with this respect too. The iPhone 5S is average but is far from bad.

Sorry, but I did not see a single sharpening-induced halo. I work in 3D imagery (not 2D) and I believe I would notice. If you want to prove me wrong, I'd be glad.

No need to use lanczos resizing when you can inspect the photo with a simple zoom. I just used the built-in zoom of Flickr.

Again, the major problem on the Z5 photo is the blur on the sides. I believe other good smartphones have wide-angle lenses, don't they? Do they exhibit this much blurriness? I feel attracted by the wide-angle lens, but I will feel disgusted if another phone is released this year with wide-angle, and with no blur.
[Xperia Z5 General] gm007:
This @8MP superior auto and the blue is there on the corner where it supposed to be black.
[Xperia Z5 General] EQ2000:
That is usually a side effect of high ISO combined with color correction as high ISO tends to 'overdo' the colors and light of the captured scene. Blue is main component when trying to reduce a yellow hue and since most lights both indoor and outdoor tend to be warm the blue tone will be there with high ISO and post-processing by BIONZ. Earlier Xperia Z phones barely have this blue color tone but in return have way more yellow.

You can to a certain point simulate it on a photo with no blue hue but that has a yellow tone. R -10, G +5, B +30-40 in image editor. Ofcourse would be different with RAW but you get the point.
[Xperia Z5 General] gm007:
I know how colors work but why this is not happening with other phones?

Sony need to change their developers they are bad at software development(from z2 to z5 i had the same bugs experience,till now they don't know how to fix auto brightness for example).

Even tho i like this phone cause its one of the best in the market today and hope some updates will make things better.
[Xperia Z5 General] EQ2000:
If you know how colors work you would know this is a fix for current tech limitations. Other phones do it but to a lesser degree becouse there is no other mobile phone which even comes close to the ISO cappabilities of Xperia Z1+. You can for example check GSM Arena and see low light photos of different phones and you will notice that other phones at high ISO will have a bluish tint or desaturation. Especially noticable in black areas as driving the blue channel up will make black more bluish and is more of a contrast and thus more noticable than on other lit surfaces in the photo.

In the end you got to choices, get bluish tone of varying degree while trying to neutralize overblown color(s) at high ISO, just have pre Z5 algorithm where the dominating lightsource color will dictate the hue color or go for heavy desaturation like Iphone 6s does for their high ISO mode (which aint even near the Z1+ lines quality).

Point is the bluish tone is way better than a strong yellow hue (assuming dominating lightsource is warm with yellow/orange tone) which.. is damn hard to correct in an editor compared to a blue hue.
