Is the Telephoto lens fake? - Xiaomi Mi 9 SE Questions & Answers

I was just curious which lense corresponded with which camera mode. I did this by covering each lens with my fingers, here's what I found:
TOP: ultrawide
Middle: standard
ok... good so far...
switch to 2x mode ... still using middle lens! WTF. Did Xiaomi lie? I noticed the zoom quality was pretty terrible, this explains it.
What do you guys think?

In good light condition, it use bottom Lens.
But in dim light, it is a digital zoom.

Ah can confirm! See I really wish it just used the 48mp crop in good light. The telephoto quality is worse than a crop!

Selfie quality

You're beautiful and everyone knows it. That's why you take selfies. Rate this thread to express how the front-facing camera of the OnePlus 3T performs. A higher rating indicates that the front camera produces fantastic results consistently.
Then, drop a comment if you have anything to add!
If light is very good, acceptable selfies. Indoors, even with good light, usually very blurry shots
Indoors, nothing but TV for light and taken straight from Allo
At low light in front of my monitor:
beautify mode of the cam/app is the best, makes my ugly face so sweet !
for real, its pretty decent (the front cam).
With 16mp front camera the photos look crisp and sharp. Nothing bad to say about it.
Seems fine with or without beauty mode it's almost same for me
absolutely amazing with the 16m front camera

I recently went on a trip with a selfie stick...front facing camera turned out to be pretty bad...they all turned out kind of like this one:

Some look better than others, but everything looks soft and out of focus...is this normal?

The front facing camera has fixed focus, made so that the subject is in focus when the phone is at arms length. this photo looks like it was taken with a selfie stick so you were not in focus.

Well that explains it...are you aware of any work around for this? I imagine the limitation is the software.

I believe that it it a hardware limitation, so I'm not sure how a software upgrade or any workaround might help significantly. Maybe you might want to try the back camera instead or use the front camera at arms length, or be somehow lucky to find a clip-on lens that can either increase the camera's field while somehow still keeping the correct focus distance or a clip-on lens that will correct the focus when the device is on the selfie stick.
Good!
The front camera is really good. Clean and bright selfies. Love it.
Amazing, outstanding camera quality...
Such a awesome phone. It have best camera that is very useful for taking high resolution selfies.
low light sux
Well lit ok

Xiaomi mi6 optical zoom is actually digital?

Hello guys,
Ive been playing with my mi6 for a while and noticed a strange thing. Photos captured at 2x look actually more like a digital zoom than an optical, even though the resolution is the same as 1x. When you actually cover the left camera lens, the picture is still normal. No matter if you choose 1x or 2x.
Any ideas?
Thanks in advance.
You can explicitly set the lens on manual mode.

Thanks, you da real MVP!
Where can you change that? Still on MIUI8.
it does that in low light shots, cause the tele lens is so bad at low light that it prefers to shot in main camera and zoom it in.
sources : miui forum? red it when i bought it

That's right, the telephoto sensor has 1.00µm pixel size at f/2.6 aperture, while the main sensor has 1.25µm pixel size at f/1.8 aperture.

Bottom (telephoto lens) camera just a fake/dead?

So I was bored and watched a YouTube vid on a mobile camera review. And wondered which camera was where on the back of my N10+.
After holding a finger over each lens, I concluded that the ultrawide lens is on top, the "main" lens in the middle. (as the marketing material and Google says) But the telephoto (2x zoom) doesn't "black out" when holding a finger get the bottom lens
None of the 3 options are "blacked out" when holding a finger get the bottom lens. The bottom lens moves slightly when you change from one of the other lenses
Can someone please explain that?
Is the 2x optical zoom just a 2x digital zoom of the main lens?
x2 zoom lens is only active in good light, if the light is low cameras logic will pick normal lens and use digital zoom, which supposed to have better quality that way. So I would assume you were doing your tests in low, artificial light, try it again in daytime.
Yup. He did the experiment wrong.
On your camera with 2x zoom, then move your finger slowing from bottom and you can see ur finger covering the bottom lens. Once you move your phone in different direction, the screen suddenly clear again but your finger still covering the bottom lens. So It did use the normal lens once telephoto lens is in the dark.
Lol, I have seen this same doubts\claims since the note 8 times
Aaah lol ? didn't know that.

Unable to select tele-lens on LG G8s

Greetings Just got my hand on a LG G8S here in Norway and I'm pretty happy so far. I started exploring the (three) cameras and noticed today, that if I covered the tele-lens, it did not make any difference. Activating the zoom mode (big tree icon) still provided an image, showing that it was just using a digital zoom on the main lens. Wide lens works fine however.
I also noticed, in manual mode, I could not activate the tele mode at all. Seeing also that the aparture did not match the tele one witch should be f/2.4.
Could it be that I have a G8 firmware, which only supports two cameras?
Thanks!
Pål
Try This.
Guess this scenario is been discussed and tested on other LG triple camera phones with Telephoto lens.
G8s telephoto lens with F2.6 needs good light to work, in poor lighting it switches back to the main/standard lens and offer digital Zoom.
Try outdoors with good lighting,switch to tele lens and then cover this lens with your finger.
Not sure why the software has to decide which lens to choose, May be this is the so called AI camera feature
Try gcam. It uses telephoto lens even at night
Hey, if you want to force the use of the telelens lens long press the little tree button, and it will show a live mini-preview of each lens. Choose the tele view and take the picture. You'll notice the difference in the quality and stability of the preview opposed to when you try to scroll smooth past 1.9x zoom.
But you won't be able to do anything else but snap the shot.
As soon as you click in something out of this preview option, whether to adjust exposure or anything, you'll notice you'll leave the telelens to the main sensor 2x digital
It's not ideal, but Works... Looks like a.... Bug?
Know this has been dead for a while but I investigated this and it bases the lens selection on focus distance and light availability. If you try to use the tele lens on close up subjects it will auto select the main sensor. If used for shooting more generally the tele lens is selected. I imagine light availability makes a difference too. I wish it wasn't blocked in manual camera mode though.

Question Photos flares.

I think Google should give a notice on foto flaring... Pixels has one of the worst flare effects...
What do you think about it?
Have you tried switching from wide angle to standard camera? (0.7x, 1, 2,4x zoom)

Standard camera Flares
Light is reflecting off the lens. Since they probably don't make any ND filters, if you have some old sunglasses that aren't too dark, try placing the lens over the camera sensor. The lenses on my d-slr have coatings to help reduce it, along with the lens hood, but if you are shooting directly at bright light, it can still happen. When it does I just photoshop it out.
You can also try settings in manual mode (I use camera FV-5) to set the f/stop at a different setting to change the exposure.

Thanks for the tips... I already knew some of them... Google should do something deleting them using software... S21 ultra and s22 ultra have reflections of the lens too but don't have so annoying Flares..
It is more the light reflecting off the glass sheet that covers the whole of lens assembly than just lens flare, a cheap skin on it reduces it significantly. When using the night modes however it is difficult to stop simply because you are using multiple exposures and therefore stacking any flare on top of itself and multiplying the effect.
FWIW you cannot change the aperture, they are fixed and there is no diaphragm to open and close, hence the reason why you get really, really high shutter speeds when the light it good.
You will be able to alter the shutter speed though I'd have thought, it is an electronic shutter so it can pick any number it sees fit to limit the light coming to the sensor.
