2x lens disabled in low light? - Sony Xperia 1 Questions & Answers

I just noticed that my 2x lens is not enabled under some circumstances, covered with my finger the middle lens (2x) to confirm, and you can still use normally the 2x zoom option in auto mode, it seems it doesn't switch to the 2x lens, and just zoom in the main camera.
In service mode all lens are are working as intended.
EDIT: it seems this occurs only in certain conditions like low light situations

It's just with auto trigger (auto mode using zoom).

This is normal and happens with most phones with more than one camera.
If you cover the 2x lens before switching to it and then you try to zoom in, it will detect that the lens is covered, so it will only zoom in the main camera lens.
Furthermore, if you switch to the 2x lens in low light (below 100 lux of brightness), the 2x lens will not be used and it will continue using the main lens.

How exactly does the S9+'s telephoto lens work?

Hey guys. So I've been tinkering with the S9+ and its telephoto lens and I've noticed something weird about it...
So basically, I got one of those clip-on lenses for when I still had my S7. So I figured if I used the 2x on the telephoto, it would get 4x. Odd thing is when I switched over the 2x and had the clip-on lens on the main (top) camera with the telephoto lens effectively covered, it still shows an image (which actually looks 4x!). So does that mean that the 2x still shows the feed from the main cam? Doesn't the telephoto lens have its own sensor?

The telephoto is used only when it detects good light conditions, otherwise, it will be a crop of the main sensor.
You can do the test yourself: in good light conditions, change to the 2x and you will see is using the telephoto sensor; now cover it with your finger and you will see your finer approaching and after a couple of milliseconds you will see an image again. This is because the camera detected no light in the telephoto and changed to the main sensor.
Take out your finger from the telephoto and you will see how it changes again.

How to lock F2.4 lens no matter lighting conditions?

Helo everybody,
I am wondering if there is a way to lock F2.4 lens with 2x zoom no matter lighting conditions? I am so frustrated when we get digital zoom instead of 2x optical zoom because of bad (under 100 lux) in worse than optimal light. It's F2.4 optical stablised lens so why digital zoom? That sucks don't you think..?
honestly, you'll be surprised on how bad the tele lens in capturing light.
You can play with this. Go to live focus mode, turn the blur effect all the way down. This will force the tele lens to be used. Make sure dual capture is ON.
Now go to your gallery and find that pic, compare the picture in Close up Vs. Wide. You'll be surprised on the difference between the two lens.
What boggled me more is the fact that the tele lens is the one that they used for the Slomo mode. You would think that they would use the main lens with brighter aperture for something that requires soooo much light.

low Light problems photos from stars distorted with S9Plus

Hello,
i take photos from the night sky since serveral years (with smartphones too).
Unfortunately with the Samsung S9plus the stars are not pinpoint like as they are on the Samsung S7. They apear very distorted with a kind of a halo.
Ofcourse the smartphone was not moved during 10 seconds of exposure time.
I did layed it down and used the self timer mode to prevent shaking.
I tried it serveral days in comparison with the Samung S7.
The S7 is always much better and show pinpoint like stars.
The distortion of the stars is visible in the RAW files(DNG) too so no jpeg problem forced by the compression.
Could you reproduce the same problems?
I am not allowed to post links.So how to show you the photo?
Could send you the link of the uploaded photos for comparison.
The dual camera variants of Samsung phones tend to overexpose shots, especially during darker environment.
That's what I noticed, and I'm waiting for the update they sent to Note 9s.

Are you using the telephoto camera? It has OIS driven by digital gyroscopes. Those gyroscopes aren't effective at low frequencies so the OIS will slowly drift around a small amount. 1/5 second is usually the limit for sharp photos. Even when the gyroscopes are turned off, OIS lenses are VERY sensitive to motion because of the lens being on a soft suspension. Walking next to the tripod could wobble the lens.
You also can't expect clear images if you use F/1.5.
Try using the wide angle lens.
I would send a photo to someone of you so you can post it here into the Tread.
Who like to do it?
The camera was layed down on the ground so no shaking or vibration ppossible during the exposure time.
I found no setting that the OIS gyroscope is working in photo mode. OIS is probably only working in video modes.
Even if it works in photo mode, the camera was layed down, so no shaking could happen.
Who of you could make a photo from the stars with the following settings?
Pro Mode
Camera mounted or layed on the ground with direction to the night sky.
Self timer to prevent shaking
Iso 800
10sec shutter speed
F 1.4

Antwort unfortunately the tele lens only works in very good light conditions.
Even in a bright lighted room there is no way to activate the real Tele lens. The camera automatic switch to digital Zoom.
Also in pro mode its not possible to use the telephoto lens if the light condirions are not perfect.
This is very bad because if the cameras is standing still completely and the object doesn't move why not using the Tele camera lens in pro mode?
Very interesting Thanks for the link

Telephoto camera bug - Phone always uses normal camera at 3x zoom

I first noticed that my optical x3 photos had a fair bit of digital noise to them.
I then tried pinching to change the zoom and I couldn't see any transition between the lenses when going from 2.9x to 3x. You should be able to clearly see the transition between 0.9x and 1x
After covering up all the lenses one by one with my finger and changing the zoom level, I can see that the x3 view (which should be using the bottom left lens, as you are looking at the back of the phone) is only blocked when I cover up the standard lens (top right)
Can anybody else verify this? Is this some strange intentional behaviour or a bug?
Confirmed on my device too as a bug when viewing the screen.
However, if I try taking a photo the camera switches to the 3rd sensor to actually take a photo.
Must be a new 'improved feature'.

IMHO I suppose it's so by design, to allow the user for a smooth zooming experience, and it can be considered a bug only as far as the correct lenses are not used to take the final picture.
I think it's to do with the minimum focus distance to be honest. If you're trying to focus on something far away it will switch but something close it will switch back.
I think, the camera changes at zoom 3x if there is enough light, otherwise it will use the main sensor. I tested this by holding the camera on TV and on my low board, the room was dark.

Camera 📸

hello, I noticed that the middle lens is useless, while in the screen I tested the 3 lenses by changing the mode.
Hello,
The second camera is the 50mm equivalent lens, aka the x2. It only works if there is enough light, else the phone just do a crop of the main camera. No way to force use the x2 on the mark I.
