K20 Pro - 3 camera sensors ?! The upper one doesn't seam to be used. - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hello all,
As I said in the title.
Out of boring I tried to see , physically which of the camera is for tele, wide and main.
While putting my finger on the camera, I discovered that the first camera in the row is not used at all in the software ...
Can you, please, check too ?

It's used for 2x... I just tested it.

Well, when you zoom into 2x in stock camera app, it automatically changes to tele camera. But if you cover the tele camera, it reverts to 48mp main camera.
But in some lighting conditions, it uses 48mp main camera even you zoom it 2x

I've noticed that too, it's used when in portrait mode thought. You can even trigger a weird behavior by changing to portrait mode and back to photo mode, then change to 2x zoom and telephoto lens will be used (like you would normally expect), then changing zoom levels randomly you can get to change 2x zoom to main sensor again.

It's uses digital 2x zoom when light is low and uses telephoto camera when there is enough light present

Not using tele lens when zoom 2x in normal mode

Mi 8 camera app not using to tele lens when im zoom 2x in normal photo mode. I close main camera with finger and its still close when i zoom. Only use tele lens in manual mode. It just me or mi 8 camera app behave like this?

Thanks. Its true. It change to tele lens when i try this outside at brighter area. I only try the camera in my house for past few day.

Is there a way to use the 3x optical zoom lens?

Using 3x zoom in the camera doesn't switch to the 80mm lens. It just gives a crop from the 40mp main sensor.
Is there a way to actually use the 3x lens?
In my case to make it work I force Focus, after that i can see the swap between lenses.

How do you force focus? I tired manual focus and it still didn't change lenses when going from 1 to 3x

Just tap somewhere in the picture and it will change to the optical zoom lens.

That doesn't do anything but use a crop from the 40mp sensor to give a fake "zoom". You would get the same results using the 40mp mode and cropping the image yourself
I'm convinced the optical zoom lens exists for nothing but marketing. The only lens on the back that is ever used for any photos is the middle lens.
Maybe it is something weird with mine. You can check this by covering the other lenses with your finger

You must use it in enough bright environment because it won't switch to zoom lens when it's not enough bright.

Dude, everyone can see the lens switching, the telephoto one have OIS, i use the zoom all the time, if i cover the telephoto lens i cant see anything, so yes the telephoto is fully functional and not a made up marketing, in pie they even added a toggle to the HDR mode so you can get HDR pictures using it faster. (in adroid oreo you can manually zoom until 3x on HDR but now alot easier). the only times you cant use it and the phone will switch back to the main lens, is:
1. At Night or when theres not enough light.
2.If you try to focus a object that is just too close.

I was wondering why my indoor 3x zoom pics were so poor. I had tried covering the zoom lens in the past, proving that it actually does switch between the two lenses. What I didn't realize until now, is that when the camera doesn't have enough light, the zoom lens isn't used and the 3x becomes a digital zoom using the main (middle) lens. You can easily see this by turning on the 3x zoom, covering it up, and shifting a live view from a bright window to a dark area inside - when pointing outside the lens is blocked, but when you swing around and point the camera inside you can see the image (because it is no longer using the 2x lens).
That explains the poor indoor zoom shots I've been taking - thanks!!
Now I still need to find out what the monochrome lens is actually doing in colour photos. Playing with blocking the lens only seems to have an effect in monochrome mode, but it is supposed to contribute to capturing all photos. Any suggestions...?

How to enable zoom in 48mp mode

Is there any way to enable zoom in 48mp mode in stock camera. Its a waste not to have zoom at that resolution
No, & will never have.
You're getting the final image as 48MP so can zoom inside that all you want & good for editing later on.
Doesn't zooming in on regular camera mode switch from camera lens to other camera lens?
So, it basically switches to 48Mp lens when you zoom 2x?
Edit: it does. Lower lens is for 0.6x, and middle lens is for 1x and 2x. Same lens is for 48mp. Upper lens is probably focus lens. Try choosing mode and covering lens with your finger, and you'll see which is which.

Upper lens is 2x Zoom. But only used in good lighting conditions. Otherwise the 48MP Camera is used
Can you explain better?
When i try to zoom in the 2x camera, still the 8 mp camera, dosen't change to the 48 mp camera, i can only use the 48 mp camera on portrait mode ou in pro mode, and on the pro mode the 48 mp camera is named "telephoto". I don't know... There's any chance to this happen beacuse of any software problem?

Sony camera app does not use the telephoto lens?!

Recently I noticed that the stock Sony camera app does not use the telephoto lens at all !?!!
I am on the stock Android 11 (59.1.A.2.28).
Can someone else confirm or reject this?
You can simply cover the telephoto lens with your finger and switch the zoom to 2x on the camera app... (The telephoto lens is the lowest one on the back)
When I installed another camera app (Open Camera for example) it can take pictures with the telephoto and they definitely look different that that taken with the Sony app and 2x zoom.
This finding shocked me a lot! What do you think?
It turns out the software decides weather or not to use the actual telephoto lens based on lightning conditions and maybe something else..
Sometimes it actually uses the telephoto, sometimes doesn't...

Tried Open Camera, but couldn't use the wide camera, I just could use with the Sony stock camera.

What is going on with the cameras? Is there something wrong with the specs?

I discovered something strange with my S20 FE. When I open the camera and try the ultra-wide, the wide and the zoom, the last camera module is never used! I tried this by blocking the cameras with my fingers. So the middle camera is used for both the wide and zoom mode, which means that the device does not have an optical zoom camera OR the optical zoom works in a different way than I thought!
I also tried to take some pictures while covering the cameras, just to see if the viewfinder uses different cameras than the ones that are used for the actual shoot, but the result does not change (zoom photos are taken using the wide).
So here are my questions:
1) What is the bottom camera used for?
2) How is there an optical zoom if both the wide and zoom photos are taken using the same sensor?
3) Is this the same sensor/approach like in S20 which uses an 64MP sensor to shoot 3X hybrid zoom?
4) Anyone that has used the bottom camera to shoot anything? Are the specs wrong?
I've got the 5G version with the Snapdragon 865.
UPDATE!
The bottom camera is used when zooming more than 10X!!! This makes things more complicated!

Actually, the 3X camera works when there's enough light, otherwise, the main camera will be used.

1) The bottom camera is the 3X optical zoom.
2) As I mentioned above, depends how much light you have.
3) The zoom sensor of s20/s20+ is different, they don't have optical zoom , just hybrid.
4) The camera works perfectly, daylight photos, night photos with wnough light, moon photos.
