Is the maximum camera exposure really 1 second? - Sony Xperia XZ Premium Questions & Answers

Hi all,
Just got mine today, really dissapointed with it tbh, they can't really have set the max exposure length in manual mode to 1 second? Is there an option I'm missing somewhere? Is it just a software limitation I can get around with some different software?
Thanks

Use a third party camera app for that. But tbh, if you want long exposure photos you should really get a DSLR. Long exposure on phones is not the same as long exposure on DSLR.

I already have a DSLR thanks, but I don't take it with me everywhere Decided to return the Sony, very dissatisfied with how a premium phone with a full manual camera mode is limited to 1s.

That is very surprising - HTC U11 goes up to 32s.

I also found this flaw pretty disappointing.
The other thing that's stopping me going over the the XZP already, is that you can't manually adjust BOTH ISO + Shutter Speed. Manually setting one value (eg. ISO 50) will cause the other to be set to auto.
Not sure what their reasoning for this is, as it seems kind of backwards. Appears to have been like this since the XZ when I had a play around with one of those too.
If only you could run the Huawei P Series camera app on an Xperia (wouldn't hurt to have a B&W lens as well!), and it'd pretty much be as close to perfect phone as you could realistically get, for me.

Anyone found a decent camera app that's not laggy?

Hi Folks,
I visited the fair today with my boy which arrives in the city once a year.
My boy was on the rides and I tried getting a few photos of him with my 20mp Sony Xperia Z3....
By the time the photo was taken, my boy had already gone by....
The camera is soooooooooo disappointing, but has so much potential to be good.
Has anybody discovered a decent camera app yet, that has no shutter lag and one that makes full use of the camera?
If I don't find something by November, I'm going for the Nexus 6 :silly:

Haven't tried a different app yet, but I may have something else for you. It's the autofocus that delays the photo.
1. Use the camera button
-push it down slightly, it should focus
-once it has found the focus, just keep holding it slightly
push the button completely if you want to take the photo, it should be without a delay now.
You can also use a different type of autofocus... Have to try the different modes for myself.
Also use manual mode, depending on the light conditions and the movement, you want a high shutter speed and if needed a higher iso, which gives you a sharper image while moving.
Damn, someone should write a guide for the camera
Thanks for this info. I'll give it a go
I'm not sure the camera is quick enough to capture moving stuff. I have tried a lot of modes and can't seem to sort it.
With an awful flash too, in sub par lighting, like parties, this is a recipe for absolute disaster. Can't believe Sony didn't sort out the camera flash.

Sony has the ability to film and during film to make pictures. I do that for fast moving pictures, like filming friends that pass by during marathon's. You can then decide to keep the film and the pictures. If you only want pictures, delete the film afterwards. This way you can start filming in advance and you are sure you are not too late and you have the risk your camera is not ready yet.

I haven't tried it yet, but have you tried the Timeshift burst? I think this is what we should use when trying to capture moving objects.
Yep, that is even better than my idea!
As a general rule, I only use auto on any camera when there is no more than one thing away from perfect conditions:
If it's motion but in great lighting, auto is ok.
If it's dark but the subject is still, auto is ok.
If it's a bit dark AND there is motion, you are gonna need to set up some manual settings or a mode like burst to get a good result. That said, as above, focussing first is essential for moving objects. Find something that is at the same distance as the subject you want, half hold the button to get the focus point, then hold it until the subject comes into frame, then depress fully. This, combined with burst, is the best way for fast movement.
Ok, I was at a scary halloween function last night, and by the time I took photos of scary subjects, they'd gone...
There's no excuse for this camera, it's a mess...
I have a Fuji XT1 camera and I know how photography works, apparently the Xperia Z3 has 20 mega pixels - Maybe it does, but only if you want a grainy shot....It's shocking!

How can you say you understand photography when all you point to is the megapixel count? There is so much more to a good photo than resolution.
The reason I point to the 20 mega pixel is because the photos taken with this camera should be of a good enough standard to print out at a size of 18" x 12" however, the photos look grainy on screen so I'd hate to see how crap they look any bigger.
The camera is shocking, the 4k videos are too so please dont try to defend it. Its very poor!
A Better Camera is a good alternative.

Camera auto mode is horrible

Is anyone experiencing this, I don't see many threads?
Tonight I did a camera comparison with a friends IPhone 6 and the IPhone 6 was far superior in every sense. Images from the Z3 generally seem grainy and lack detail and sharpness.
I see a few people have mentioned that the camera is better of you manually set the options. This isn't what a smartphone is for when you need to snap a quick shot, by the time you've done all that you've missed the moment.
I swapped my LG G3 (which also took better shots) for this and I'm really underwhelmed by the camera on the Z3, which ironically is its main selling point.
Can anyone suggest some third party camera apps which would perform better?
Also do you think Sony will fix this, i owned the original Z and can recall having some camera issues. I didn't think they would still be present 4 years on.
The Z3 camera was hyped up so much, I really can't see why. Great on paper, not so good in the real world.

superior auto mode is basically a 8 mp with hdr and flash with some adjustments better go with the manual so you can choose a higher mega pixel.

I installed Pro Capture and it seems a lot better. Sony is doing half a job. You cannot supply excellent hardware and not take advantage of it with the software. It seems most people are impressed by the specs of the camera more than its ability to actually take a picture! I cannot believe how much hype surrounding this camera there was.
Have you tried the xposed module 'superiorauto 20mp'? which forces the SA mode to shoot at 20megapixels?

Over sharpening of camera image

Can anyone confirms this? Almost 4 units i tested from sony stalls has this issue.
The photos taken by camera turns out to be overly sharpened, with lots of artifacts.
Turning on or off image enhancements does not help.
I am seeing this as well. And most of the reviews I saw also reported this.
Currently I am trying a few third party camera apps to see if they do the same
Haiz.. Why can't they make the camera right for once?
I concurred this. Mine focused good. I learned a trick that you actually have to tap the screen then press and hold the camera button on screen or side until it is clear. When i first got it, all my photos was focusing on the wrong spot. However, now with that trick i could get sharp images but zooming in they look very blurry and a lot of noise.
Do you experience this is good or low light? You do have to work a little bit harder with the camera settings as the light drops off to get the right image. And use the designated camera button too rather than the on screen one.
Good lightings... Not to mention if its poor lighting conditions. Guess have to wait for a new firmware.
Yep so much sharpening in all lighting conditions. Hoping for a software update soon.
Here is samples pictures from my XZ. It has undoubtedly the best selfies camera under daylight. Lowlight shooting takes a bit to get used to it. It was bad as first but if you toggle on "tap - focus and brightness" in setting it will improve tremendously as it uses it light sensor to automatically brighten the photos. Overall, I'm happy with the camera. It beats Iphone 7 Plus and on par with the S7Edge. My beef with the XZ is the small size and 3GB. I would prefer 5.5 and 4GB for a $600 phone. But if you can get it for $450 or $500, this phone is definitely worth every penny.

I am not talking about selfies. I am talking about the main camera. Very bad quality here. So fall 8 sets i have tried, same issues
Noticed this myself, not impressed with the image quality. Seems to be worse than my Z2. Hoping when they eventually drop Nougat it'll iron out some of the issues.
About blure and noise, increse ev to +0.7 or 1
A very good example of xz camera samples. You can guess which photos are by xz. The oversharpening of images when zoomed in.. Soo much artifacts.
http://m.gsmarena.com/blind_shootout_iphone7_galaxy_s7_xperia_xz_lg_g5

Camera

I'm considering the XZ, however there are very conflicting reviews of the camera. Some show really nasty photos, some show good photos. I'm assuming some of this has to do with SW versions and I know the XZ recently updated to 7.0.
I can't tell anything from a tethered store display unit.
Anyone have any comments regarding photo quality?
Manual mode is fine for me to shoot in. I almost always use manual mode on my cell phones and also my digital cameras.
Thanks in advance.
I find it pretty good, the manual shutter speed goes right down to 1/4000, manual focus ISO etc.
In MM I did realise the camera quality was worse than in 7.0 - so they did improve it.
Photos I have taken have great colours, and can usually be edited quite well in lightroom.
Big downside is the no RAW support (Yet, hopefully they release it)

Colors have pretty much always been good in reports. The main thing that some of the "bad" reviews have mentioned is the artifacts especially in lower light. The better reviews and pictures that I've seen online don't really show a huge artifact problem and some of the youtube videos show what appears to be very good lowlight performance using manual mode.
I knew about the lack of raw support and I've used LR for a long time.

Sony has always been a bit dodgy with low light, but I have found the XZ really improves on that (Compared to ther Z3, and Z5) Manual mode really helps with some of that though (same as a DSLR though)
Another thing to note, the device unlocks super quickly, and same with the camera, good for those un prepared shots

I suppose that there isn't really any infor on their nrw 19mp camera used in thr XZs, nor have I found any pricing on it. At any rate it seems only a small upgrade from the XZ, with mostly the new camera and another 1 of ram
Pictures are generally very noisy and blurry when its not in extremely good light (inside with the sun shining through the windows with the lights on as well) Video however is very very good. I dont use manual mode since I don't know what to do, but as a point and shoot I can think of several phones that do better and probably cost less. If you want to buy it for the camera, just dont.

Thats strange, I hope I dont have a faulty hardware , however did you try to take indoor pictures and zoom in, you'll really notice the noise atleast, and if I'm not still as a building then it will also blur.
Sometimes the SW can overboard with the sharpening, I wish there was an option to disable it. Most phones probably have this issue too though.
I dont know if this can be counted as an issue but the lens on XZ has kind of a fish eye effect, So If you are taking a picture of an object and put it i the corners, it stretches and looks a bit... uh, unnatural? Because of this I try to make sure to center people as much as I can.
Some also say that taking pics in 8 mp mode introduces some artifacts because of the conversion algorithm (23mp to 8mp downsizing). So I use 23MP to avoid any unwanted processing.
I find the colors of the photos, taken with the XZ, to be very dull and way too cold to my liking, and XZ's Camera UI and Camera API have very limited manual controls set, unlike the rest of the flagships out there. I made a few photos with my old Xperia Pro and my new Xperia XZ for comparison, you can check them here - https://www.dropbox.com/sh/0u28226fxm9z27d/AADrU08TmvfIUtSbprgharT-a?dl=0 . I was very unhappy with the XZ's camera so I sold it one week after I bought it.
EDIT: you check this thread for more information about the limitations, related to the manual controls of XZ's camera - https://forum.xda-developers.com/xperia-xz/help/enable-manual-controls-camera-t3580654
My experience, XZ pictures have a lot of noise (you can see that when you zoom in) when the light is not enough (and the phone is the one that decides what it means by enough )
I am coming from Galaxy s6 edge + to XZ Dual, and the S6 is the winner in my comparison.
If you want it for the camera, I wouldnt recommend you to go for the XZ.

This review has sample photos in full res from XZS if you wanna know about picture quality. I own the XZ and i do see a difference in quality to the better in XZs compared to XZ..
https://www.lowyat.net/2017/128842/sony-xperia-xzs-review-one-trick-pony/
After I started using 4:3 full resolution instead od cropped 16:9 and disabled object tracking I very rarely see edge bluring and the photos in general are a lot better.
The "noise" people talk about in most cases is not really noise, it's a result of the image processing algorithm being too aggressive trying to eliminate noise even when there isn't any. First it sharpens the hell out of the photo to bring out as much detail as possible and then it tries to remove the resulting noise by applying heavy noise reduction. It's basically shooting itself in the foot. But, it really isn't as dramatic as some would say, you can't really see that effect until you zoom in really close. If Sony could find a middle ground, balance it out a bit, it would be perfect.
Sony's image processing has always been an issue for some unexplainable reason, they mastered sensors and image processing in photography a long time ago, but when it comes to phones it fails in software department, the sensor are the best on the market still.
It really is mind boggling, and they are aware of that, it's basically a software issue, it just needs some adjusting, why apply a noise reduction filter when there isn't any noise? HDR usually sucks as well. Then again, their DIS is top notch, the autofocus since the XZ is superb, the colors to me look great all around, low light photos are very good, specially in manual mode with adjustable shutter speed...there are great things about Sony's cameras, but usually things average user doesn't really see or cares about.
To be fair, the only time I see those artefacts is when I zoom in, not even when watching fullscreen on a PC, so I'm really pleased with the camera on Xperia since the Z3, but all things considered, Sony should have the best smartphone cameras in the world or at least be the top 3.
All that being said, shooting in manual mode is a different story, once you get a hang of it and learn how to use it, it can stand besides the best of them, easy. But that's not really a fair measurement, only auto modes, because that's what most people will use, and that's where Sony usually doesn't do that great.
The phone takes great photos, and I have yet to see a review that says it's a bad camera. It really isn't, it just isn't at the top few as it could be.
As for the XZs, currently it often produces lower quality photos than the XZ, depending on the scenario, it isn't a better camera, it's just different and has different strenghts in different scenarios. Plus, the slowmo gadget, if you care about that stuff. Other than that, there is no reason why it should be a better camera in average scenarios, maybe in low light because the pixels are bigger, but that's pretty much it.
If the quality of photos is your only concern about buying an XZ (or XZs, for that matter), you shouldn't be worried.

Still room for more improvement in Essential's monochrome camera? How does P20 do it?

So as seen on dxomark , the Huawei P20 pro is now the king of phone cameras, and one key thing is that it has a second monochrome camera just like the essential. Perhaps they figured out how better to "utilize" the monochrome camera much better than the devs at Essential?
i love my essential and i think is hope that it can be even better!

There are a lot of ways to use the monochrome camera.
You can possibly use the image for increased dynamic range or contrast.
I use the Google Camera port for most shots, and use the OEM camera for B/W shots, which it does very well.

How do they do it? Better hardware that's how
I don't think the way Huawei incorporates both cameras is better hardware, it's much better software. Huawei uses what they have better.

The hardware itself, i.e. the cameras, are better quality. We can argue this all day, but you can only polish a turd so much (fix poor quality hardware with software)
The P20 Pro takes amazing pictures because Huawei put an amazing primary sensor (and lenses) in the phone along with good image processing.
GCam demonstrates the limit of image processing (taking low-light images being more detailed than the monochrome camera on the stock app) but without better camera hardware that's as far as this phone can go.
What better hardware? The P20 can get about 50% more light per pixel which is half a stop which amounts to nothing in the photography world. DSLR sensors gather 10 times or more light than phone cams and yet DSRLs are dying.
In the smartphone camera world, software is everything. Remember that the LG G6 has the same sensors as the PH-1 and yet its DXO scores for texture and noise are way higher than both the P20 and the Pixel 2. And that's the scores for just a single sensor. The Xiaomi 5s also has the same sensor pair in the same arrangement as the PH-1 and the combined output trounces any single sensor in the smartphone world.
Essential is really behind in their software department, notwithstanding their commitment in software support. Despite of the fact the camera designer was the one behind the iPhone's portrait mode, their software still can't live up to hardware potential. The current stock cam app, even with combined sensor output, can't come close to some GCam mods which use just a single sensor.
---------- Post added at 12:08 AM ---------- Previous post was at 12:03 AM ----------
The P20 Pro, on the other hand, got the good low light quality only in 10MP mode which pixel-bins the 40MP down to 10MP. Its texture and noise scores are still no better the than the G6. At 40MP its low light quality is worse than crap.
Yeah no.
You can't go using "it's nothing compared to DSLR's" when the difference is 50% more light per pixel. DSLR's are not dying because of quality but because it's convenient to have a good enough camera in your phone.
Obviously software is the key for modern cellphone imagery, that isn't even the point here. We already know what better processing does for the Essential sensor in the GCam mod. Which also works on the G6 incidentally and yields generally better results than LG's own app. But on the whole it's not nearly as good as the Pixel 2 for instance. Don't give me "but DXO said" because even G6 users don't believe they do better.

I didn't say "it's nothing compared to DSLR's" . If you don't understand, I'll say it again: 50% more light is half a stop which is nothing in the photography world. Do you even know what 50% more light means?
DSLRs have better hardware, but are dying not because of lack of convenience, but because quality from smartphone are good enough these days. Convenience was always there from the beginning of the smartphone age, but quality has only gotten good enough a few years recently. DSLRs always have the hardware advantage, but smartphone have the software and that's what make the difference.
And G6 users can't do better than Pixel 2 like DXO because they don't know what to do to get as good as DXO, at least in terms of texture and noise. "On the whole" is another matter since it's the whole package, which means Google software is much better than LG software. Well, it's the software that makes the difference. That's the point I'm making. It's not the camera hardware, it's the software. Differences in smartphone camera hardware are peanuts.
He also neglects to mention OIS on the g6.
Also, the Xiaomi Mi 5s Plus has the exact same design, with the same two Sony IMX258 sensors, one RGB and one Monochrome, no OIS, and it has the exact same problems with low light, even in daylight, and shutter lag. That phone was released a year ago. So Xiaomi proved this idea is a failure.

Since you mentioned OIS, what does OIS do to make the sensor output better, specifically texture and noise quality? If you don't know, it does exactly jack squat nothing to the sensor. It helps with the whole package, but that doesn't make people like it more than the Pixel 2.
And the Xiaomi 5s is not a failure, at least in terms of camera quality. The least you could do when trying to argue against it is to look up review results for yourself. Look at the comparison tool at GSMarena for the 5s in stereo mode compared to any other phone cam, instead of talking about something you know nothing about. People make the results and tools available and you don't even bother to look at. Sad!
Why people make unsubstantiated claims about something they don't understand or even try to learn about? Opinions can always be different, but at least have some informed opinion.

Lol you're one to talk. You don't think OIS effects low light photos? Interesting. You should do some reading. Noise levels in low light are highly related to OIS.
It is ranked about the same as essential phone by most reviewers.
If you're going to call me out, at least be right

Absolutely not. OIS reduces vibration from your hands to help getting sharper images. Same exposure parameters with or without OIS give exactly the same noise level. It does nothing to help noise from sensor. If you think it does, explain or cite how it does.
The effectiveness of OIS on smartphones is dubious at best due to the very short focal length on most phones. If it's really effective, those gimbals wouldn't be in high demand or that expensive. But this is another matter unrelated to the photo quality of sensor output.

"If your camera meters the need for a slow shutter speed which will cause camera shake, there are two ways to switch to a faster shutter speed:
1. Open up the aperture. Opening up the aperture (makes the hole bigger and therefore) allows more light to come in and so reduces the time the shutter needs to stay open. ["Shutter speed" is simply the time the camera keeps the shutter open.]
2. Often, especially in low-light situations, this will not even give you a fast enough shutter speed to hand hold the camera, so the second way is to use a higher ISO."
"At this slow shutter speed and without using a tripod, we will obtain a blurred image if we hand hold the camera. But, with Image Stabilization, we are now able to hand hold the camera without worrying about camera shake (1/15 sec. is 2 stops slower than 1/60 sec.).
If the light level falls further and the camera now needs an even slower shutter speed, say of 1/4 sec. (that's 4 stops slower than 1/60 sec.: 1/60 sec., 1/30 sec., 1/15 sec., 1/8 sec., 1/4 sec.), Image Stabilization will not help us eliminate camera shake in this case. It will, however, reduce its effect.
Note that IS works irrespective of the ISO used. Whereas High ISO forces you to use a high ISO (with resulting high noise and image degradation issues *1), IS allows you to keep at a low ISO while still reducing camera shake (thus keeping maximum image quality). That is, it does not mess with your selected exposure settings (you keep the shutter speed, aperture and ISO you want to use)"

"If your camera meters the need for a slow shutter speed which will cause camera shake, there are two ways to switch to a faster shutter speed:
1. Open up the aperture. Opening up the aperture (makes the hole bigger and therefore) allows more light to come in and so reduces the time the shutter needs to stay open. ["Shutter speed" is simply the time the camera keeps the shutter open.]
2. Often, especially in low-light situations, this will not even give you a fast enough shutter speed to hand hold the camera, so the second way is to use a higher ISO."

Hmm, that's a lot of quote, but not sure how much you understand or believe in all that. How do you adjust any of those settings with any (except one) cam app?
Whatever exposure setting you take a picture at with OIS on, I can take another picture at the same setting with OIS off. The noise level will be exactly the same. There might be a difference in sharpness, but how much difference will depend on how firm I can hold the camera or if I use an external stabilization device or not.
Like I've said, it helps with the whole package, but it doesn't explain how the G6 get higher noise score than the Pixel 2 which also has OIS. It's all in the software.

What that user was trying to convey is OIS let's you use a slower shutter with less motion blur due to camera shake. Slower shutter equals lower ISO, which likely results in less noise. This doesn't help for moving subjects though.

That's the theory. Slower shutter speed *requires* lower ISO for the same lighting level, since the aperture is fixed. But in practice, I wouldn't give it up like that, but rather try to brace myself to reduce vibration or just use a stabilization device/tripod so I can shoot at the same exposure setting and get the same acceptable noise level.

I think you have it backwards.
A slow shutter allows you to use a low ISO.
A fast shutter requires a high ISO.
This assumes shutter an not aperture priority.
Also 1/focal length is the minimum shutter speed to not have noticeable shake at correct lighting.
I feel like this has gone a tad off topic. Not to say its completely irrelevant but I feel the starting point is, us comparing both the Ph1's and the P20 implementation to know whats different.
