Question 3x 10x camera - Samsung Galaxy S21 Ultra

is it normal in S21 ultra if i try to make a 10x photo, in some situations the 10x is a digital zoom from 3x camera?
i tried covering the cameras with a black paper, when i select 10x focus, if i'm in an open space the 10x camera (periscope) goes black, but if i'm in inside home on a long room (8 meters long) and selecting 10x focus the image goes black if i cover the 3x camera.
there is an application or something to see which is the lens in use when i shoot a zoomed photo??

Hi, you can check EXIF info (Select photo in gallery -> three dots/details) and verify the aperture
f/1.8 = 1x sensor
f/2.4 = 3x sensor
f/4.9 = 10x sensor
Depending on the light conditions, digital zoom or optical zoom will be used. This is because as you can see, the larger the zoom, the more closed the aperture, so less light enters the sensor, and the software thinks that digital zoom is better for those circumstances..

thanks, i was thinking it was for the short distance (8m indoor)

hello, Has anyone ever used the depth sensor on the s21 ultra to scan 3d samples yet, is it as effective as the lida sensor on the ip 12 pro?

Hi, sorry to disappoint you, but the s21 ultra has no depth sensor but a Laser AF, it only works to improve autofocus in photos and videos. There is no point of comparison with the iphone 12's lidar sensor.

Using both CAMERAS at the same time

I saw a topic from P9 forum where folks discused the question- wether the phone actually uses both camera sensors at the same time... How is this with our p10? I tried to take some close-up shots with BW covered/ normaly- and there is 0 difference- same quality, size etc...
- Only case when I see actually both cameras working hard at the SAME TIME is when using bokeh mode.
BUT WAIT A SECOND. Huawei states that colour sensor is only 12MP ok, but how on the earth it came down that I was able to take 20MP pictures with BW covered???
Sooo, have you discovered something about this? I will try to take some far away landscapes tomorow and see if something changes then...
A Long time ago i think about the Same
How my P10 can take color pics in 20mp when it just have a 12mp sensor

It would be logical, if phone used both sensors at thr same time- buy using BW details combined with colours from 12MP. BUT i tried several times to cover that BW sensor and camera doesnt give a deamn, it takes 20MP colour pics anyway...
I read something about this months ago.
The camera uses both sensors in 20MP and HDR mode.
When you make a 20MP color picture, it makes a 20MP b/w picture and a 12MP color picture as stretched overlay.
With the good b/w contrast it looks really good even the color sensor has only 12MP.
This is also the reason why you can't use optical zoom in 20MP mode.
The zoom works with the b/w sensor, so it's not really optical zoom but "enhanced digital zoom".

[Camera] Is it just me .....whats your settings?

Ok coming from Samsung , HTC, Asus and iPhone (I know I here you gasp)
I pretty much use my rear camera alot for work purposes, no selfies
Mostly its point and shoot I do and I know the camera on these are for ppl getting the right shot manually due to the settings
Have tried apps on this phone Like :
Camera FV-5 (same kind of results)
Open Camera (which seems to stay active in the background)
Now heres my question if you quickly take a photo, point and shoot (focusing first) using highest resolution
Once you zoom into the taken picture, its all grainy even if its took about 3-4 feet away from you
Now, if you take the same picture with monochrome its a better pic and if focusing on say a bottle with writing
Its more visible to read compared to the colour as the colour looks like its a water painting
Are you guys getting the same results or know preferred settings to use?
Thanks
Try to set the resolution to 12mp to enable the 2x "optical" zoom.
The color sensor is only a 12mp one, the monochrome sensor has 20mp.
If you enable 20mp in settings, the camera will make a monochrome and color photo and merge them into one. This is also the reason why the 20mp photos are a bit blurry or too bright on edges.
So, use 12mp and the grain should be mostly gone.
Here are three shots by me:
https://imgur.com/a/BYf7kIX - played with focus, no aperture feature.
https://imgur.com/a/xA2qURk - just a free hand picture in 12mp without zoom
https://imgur.com/a/RbEdeiI - and the same with 2x optical zoom.

Thanks for comments
Is this with stock camera? stock rom?
as My pics are no where near as good as this on 8.0.0.379(C02)

Everything stock, 8.0.0.370 on VTR-L29C432, stock EMUI camera.
Can you show some examples?
Desk is about 4-5 feet away from me when taking these shots
Sunny outside
Just normal photo and putting focus on the bottles as shown (seen in zoomed photo)
You can clearly see they look terrible apart from monochrome
No settings have been touched apart from resolution
Zoom is about 4.6x
Monochrome
12MP
20MP
Zoomed in
I put some crap on the desk but if you can see the text is visible on some stuff to give you an idea

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?

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.
