Is your Note 8 x2 optical zoom camera defective?

[Neo3D]

I think mine is defective? Try this test:

[(x2 Camera) (x1 Camera) (HR Sensor+Flash) (Fingerprint Sensor)]

1. Cover the x2 optical zoom camera with a piece of paper, tape, or your finger
2. Press the x2 Optical Zoom button on the camera app
3. Press the x1 Optical Zoom button on the camera app
4. Toggle back and forth between the two
5. What happens?

As a control, try the test again but in reverse:

1. Now, cover the x1 camera with a piece of paper, tape, or your finger
2. Press the x2 optical zoom button on the camera app
3. Press the x1 Optical Zoom button on the camera app
4. Toggle back and forth between the two
5. What happens?

So, here's what happened with my camera.

TEST 1 - x2 Optical Zoom Camera covered: No obstruction of image in x1 optical zoom mode and x2 optical zoom mode.
TEST 2 - x1 Optical Zoom Camera covered: Yes obstruction of image in x1 optical zoom mode and x2 optical zoom mode.

CONCLUSION: My x2 optical zoom camera is defective and does not engage when the x2 optical zoom button is pressed, instead the camera defaults to x2 DIGITAL ZOOM using the x1 camera. I think my phone might be a lemon but I wanted to see if others have this problem too?

There is like four or five threads on this topic, explaining this in detail and BTW I think it works the same as iphone and no, it's not defective.

The wide/main lens has better low light image quality than the telephoto lens (f1.7 aperture and 1/2.55" sensor for the main and f2.4 aperture and 1/3.6" sensor for the zoom). When taking a picture outdoors, the scene is bright enough that the telephoto lens will be used when you click on the x2 icon. If you take the picture indoors, even with artificial light, the phone sees the you get a better picture from the main lens so it uses that instead, and then crops the picture to get the zoom effect.

Look at the pictures attached. That's the same shot from the main and zoom lens. In low light, the zoom lens has worse image quality, with increased graininess from pumping up the ISO and a lot more blur from having to keep the shutter open longer to get more light in


You can try it yourself. Open the camera, aim it at a well-lighted scene (usually outdoors). Tap the x2, THEN cover the main lens and the viewfinder still shows the uncovered view.

Yeah mine "doesn't work " either.

And for the record, this is not how the iPhone I tested worked. 7plus. In my office where light is moderate but not great, the note used the main lens and the iPhone used the telephoto. If you want to force it to use the 2x, then choose live focus. Which has no other choice.

if this is the case then you should also show the reverse, as in what it looks like in good lighting situations and not just low light.
because with your example you're just repeating the problem but are not actually showing a solution or showing that there's nothing wrong with his lens. ie: you're not really proving anything.
i'm actually not that invested but just saying if you're going to prove something at least just try to do a complete job. nothing wrong with that, right?

Actually it does work similar way:

They will never be exactly the same, since they have different hardware, different logic etc. but for the purpose of this topic in low light they will both use digital zoom, instead of optical zoom, albeit at different threshold point.

the 2x lense works on the live focus.

 

[Sunnyschlecht]

yes it works fine on the live focus. your camera isnt broken. I tried it myself yesterday.
when the x2 lens is covered just a little bit it switches to the main camera and zooms in digitally.
when you then remove your finger from the x2 lens it switches back to that one almost immediately. you can barely notice it but i played with it yesterday because this post was driving me nuts!

The pictures are to demonstrate that the zoom lens takes worse pictures in low light, since most people expect that the cameras are identical except for focal length ("zoom factor"). I really didn't go good light examples since that's essentially the phone working as expected, and people have already seen millions of examples of that. So here's the 1x and 2x pictures in good light... I guess?

Really dumb question , is there a sure fire way for me to see if my X2 zoom being used is optical or not?

Is there a way (or an app) to force the use of tele lens camera on the samsung note 8?

 

[demo23019]

Working fine here if you block it will default to one camera as it detect issue if you toggle 1 and 2x it will re enable the other camera also if you just open camera app without blocking any camera both work as they should.
IDK if this is with new update but It also tells you when camera one is blocked and if you block camera 2 it says not enough light.

Again with this? If you cover the tele lens it thinks it is dark and ceases to function, plain and simple
