Nokia 7 Plus not using Telephoto lens for zoomed images - Nokia 7 Plus Guides, News, & Discussion

Hi,
So the Nokia 7 plus is supposed to have a Secondary telephoto lens for 2x optical zoom. But there is no way(not that I am aware of) in the Nokia camera app to use that lens.
There is a button for 2x zoom in the camera interface. But when you click that the secondary camera is not used. It is digitally zooms with the primary lens.
I was curious if the telephoto lens is actually being used or not, so i clicked different pictures with 1x and 2x zoom and when I compared the info of the pictures, both the 1x as well as 2x pictures were using the same 12.2MP/f1.8 lens.
simpler confirmation, switch 2x button and put your thumb on second lens
This makes the secondary lens just a decoration if you can't use it. (unless for the portrait shots, which I don't think is very convenient, but that's another story).
Am I missing something here? Is there a way to use the optical zoom features or is Nokia missing so something.
I have attached pictures I took.

It indeed uses second lens when you click 1x button. The metadata is added by camera software. If what you say is true, it's just a bug in the camera software where it just stamps the first lens info on all photos.

@spark25 The camera app has been using only the primary camera for me since I bought the device, and 2x mode is digital zoom. Even in the latest camera update. The only place where telephoto activates is the portrait (bokeh) mode.
Maybe they will utilize it in Pie, as it includes multi-camera api so there could be smooth transition between the two camera streams.
Edit: It does use the telephoto camera lens when there is a good lighting.

Try putting your thumb on the secondary lens when zooming.

Yes, and more solid confirmation :highfive:

Noisy shots on bokeh mode
Can someone confirm if pictures taken from the bokeh mode turn out too noisy and pixelated? The picture is very grainy and loses everything on zooming in.

The tele Lens only activates under certain conditions, when it can focus on far objects with good lighting otherwise it will use the normal lens with smaller aperture.

The secondary camera only works under certain conditions and I can confirm that if you your place the finger in front of it it just digitally zooms. It probably works only in good lighting.

The 2x Tele Lens only works when there's a good amount of light is available. (Since, photos taken with 2x Lens is bad at dark)
However, there's a trick that works sometimes:
Point your camera with with 2x Zoom at a bright white spot(area) or a bright white wall, the software will automatically switch into 2x Tele lens.
Keep in mind, using 2x Lens at dark doesn't give good results. The photos quality is worse at dark with 2x Lens (because of grainy and dark pictures)

Panoramic function in camera app very limited

I noticed that the angle for panoramic pictures is VERY limited. For example I could take a 360° surround shot with my Samsung, whereas my Mate 9 doesn't even allow 90°.
Is there a way to extend the angle in my camera app?

I'm getting 180°
alright, I mispoke. It's more than 90°, because of the wide angle of the lense. Sorry about that. But it's not 180°, maybe 150° ......
But the degrees are not important, I want to improve that ... is there a way?

FAKE dual camera setup on Xiaomi Mi A1? [Not Really]

Greetings my dear Mi A1 brethren! Today I am the bearer of bad news for you guys. From unreleased source codes to headphone hissing. This problem is the final nail in Xiaomi's coffin for me. I will never ever buy another Xiaomi device again.
I have reason to believe that the "dual" camera setup on the Xiaomi is FAKE! Let me show you. Follow these steps:
1) Open up the camera app.
2) Cover ONE of the two camera lenses at the back with your finger.
2) Zoom in to 2x mode (or greater).
Did you notice something? THE CAMERA LENSES DO NOT SWITCH! The main point of the Mi A1's dual camera setup is that one lens is wide angle and the other is telephoto (as mentioned on their website). When you zoom in, the app should automatically switch cameras.
Another test is that the dual camera setup should provide a background blur (bokeh effect) on objects that are up close to the camera. Cover a lens with one of your fingers and you'll see that either the camera gets blocked by the finger or the blur effect still remains (regardless of the fact that TWO cameras are needed for a proper bokeh effect)!
Both these tests prove that one of the Xiaomi Mi A1 cameras is a dummy. Has Xiaomi lied to us again? Why would Google let them do this?
Or is it that I don't understand how dual cameras work? Someone please enlighten me. I feel I've wasted 250$ of my hard earned cash on a scam
EDIT: Nevermind! I just found out it does work. But only in manual mode or portrait mode. Strange that the app does not switch to telephoto mode automatically. Perhaps in a future update.
Have you tried manual mode

Yes, I did. I've edited the OP. I feel like a goof for not trying that first
No its real!
Try that in outdoor lighting conditions.
In natural lighting cover the zoom lens, and then hit the 2x zoom.
You will notice that the zoom lens is functional in good lighting conditions, not in bad light conditions.
Same with the portrait mode, thats why it is recommended to use 2x optical zoom and portrait mode in outdoor lighting conditions.
The camera decides if it should use digital zoom or telephoto lens depending on light conditions. Telephoto zoom only works with a lot of light(like portrait). If there is not enough light, digital zoom from wide angle lens is better. This even happens on iphone 7plus/8plus camera set up(if there is not enough light they just use digital zoom). However, I think that maybe it switches to wide angle digital zoom sometimes in good light conditions.
I can understand that you were concerned but please test things thoroughly before posting (or maybe Google it out). Actually the telephoto camera have a narrower aperture then the main camera. So it captures less light then the primary camera. When who cover the telephoto camera to see if it is working or not, then hit x2, it detects that there is low light (since you are covering the lens) & hence uses the primary camera. Okay, so this is how you should have tested. First go to a very will lit environment, then select 2x zoom, and then try covering the telephone camera. You will get the proper results. Hope this helps.
It's the same in Oneplus 5, for example!
Telephoto works properly only in good light situation

If you want to know before clicking a photo which lens is used for 2x zoom just look at the animation when you use the zoom button. If theirs an animation of zooming then it's digital zoom & if it is directly switching to 2x or 1x then it is actually switching between the lenses. And it won't change with a future update too as the OP hopes. Works the same way even on iPhones. It OK to have questions but you went too far calling it a scam, fake & never buying from Xiaomi again.

Whats the role of the left camera?

Hi,
I was sure that the dual camera setup on this phone is that one camera has a wide angle at 27mm, and the second camera is a telephoto (zoom) at 52mm.
I was also sure that clicking the x1/x2 zoom button on the camera app will switch between the cameras, based on the mentioned above...but it doesnt.
Ive tried covering the left camera with my finger, and clicking the zoom button, and it still uses the camera on the right for both x1 and x2 zoom.
What am I missing here?

Enough light then the secondary camera will be used for 2x zoom. Otherwise, it's always the main camera. You can test it using manual mode to ensure that the secondary camera really works. It surely is used in portrait mode, it can't be processed instantly otherwise.

So if there is enough light, the zoom is optical, otherwise the zoom is digital?

You can say so. The telephoto lens ****ty pixel size and dark aperture really suck in low light.

telephoto lens?

did anyone noticed that when shooting in "auto mode", if you press the 2X, the phone doesn't use the telephoto? it's just a 2x zoom from the wide camera.
You can test that covering the telephoto lens with one finger and pressing the 2X.... it shows your finger for a fraction of a second and then it shows the zoomed wide camera.
the only way to access the telephoto lens is from the PRO mode... and you can notice the difference when zooming at 8X.
Do you test it in low light condition? 2x optical tele only work in bright light condition, otherwise it will use main camera and crop.

Telephoto lens pictures at 12 mp?

So I just received my OP 7 Pro. I love it to this point, though I am still evaluating whether I can adjust to the curved screen. But my question is about the telephoto lens:
We know that the lens is actually a 12 MP 2.2x telephoto lens. The 8 MP 3x pictures the OP camera app produces is a bit of cropping and software zooming. Is there a way - either in the OP camera app itself, GCAM, or some other trick to use the lens as it is actually a designed? A 12 MP telephoto picture at 2.2x zoom?
Thanks...

It crops the 12mp/2.2x zoom image to output an equivalent 8mp/3x zoom image. Just look at the differences in zoom between the portrait mode and the regular "3x" zoom option. Both are using the same lens.

And hence my question. Is there a way to capture the true 12 mp 2.2x zoom image without the OP "magic" of making it 3x zoom. Maybe I'd prefer to crop to a different area of the 12 mp photo?
Just wondering. But I'd like maximum flexibility in camera shooting options...
I know that it will be 2.2x with gcam, or with portrait mode in the oneplus app. I haven't used gcam for a while so I can't find you the latest links and downloads. But hope this info would help
