Macro lens - OnePlus 7T Questions & Answers

So, the macro mode apparently uses a motor to move the ultrawide lens slightly to change the focus. If you cover up the main camera or the telephoto, macro still works. However, when turning on and off macro, if you look at the main camera, it moves slightly, while the ultrawide doesn't appear to move. Shouldn't it be the other way around?

The main lens moves because it turns off the stabilizer at the time of switching modes. The ultra-wide lens also moves slightly when you turn on the macro mode.

Thanks. This is the first time I've had a phone with OIS, so I never realised it actually moves the lens. Just realised now that the lens also moves every time the camera is opened.

camera takes unusable pictures. but excellent macro images

I am facing an unusualy issue which has cropped up suddenly.
I am not able to use the rear camera of the moto z play for anything as all images are extremely blurry as if an opaque cover is kept in front of it. But If I use the camera from a 1 inch or lesser distance, the clarity is superb as if its only meant for macro shots.
This issue is not happening with the front camera but only the rear camera.
Please help.

Sounds like hardware problem
Do you have a warranty?

Seems like problem with laser focus, check if manual focus is working or not.
If it's working then maybe it's the laser module that's giving trouble.
PS: check if the lens is clear and there's no dust inside.
Hi,
I changed my battery yesterday and my camera is behaving the same way. Manual focus does not work.
I had to apply a lot of heat to open the screen and also on the back, to loosen the old battery. Could it have damaged the rear camera?
If I replace the camera module, the laser sensor will be replaced too?
I also lost the finger print sensor, but maybe that's because I lost the lever of the zif connector.
OP, did you have some heat on your phone too?

Fake rear second camera?

Daisy should have second rear 5MPx camera but I dont think that is even used, it feels like just a hole. Doesnt help for bokeh, in low ligh, for zooming. If I covered it image was the same. Anyone knows when this camera take any effect?
same problem, bad front camera experience

next time please read post before you write some unrelated text
I think so too
It is definitely not fake.
You can test by going to dialer and typing *#*#64663#*#*
In that test mode you can test each camera lens ( finger over lens) and that will verify both cams do in fact "work"
Not saying the software actually uses both, but the cams are in fact real

Im not so sure in my case:laugh::laugh::laugh:
edit:same for dual back camera
With the stock camera app, it does work correctly. Perhaps you should contact warranty...
The portrait mode that focus only on what is close must be a proof that the second camera works, right?
If you cover the second camera in potrait mode in stock cam app, you will see that it is not working properly anymore
the 2nd camera only there to enhance DOF information
not to actually take a picture.
front camera is also able to fake the DOF but its slower and not so accurate when compared to the rear camera

This works for me! Thanks. I don't know why others doubt their smartphones
i also use this model and i think that secondary dual cam is just for show off it does not do any thing. its a mimic only for branding purpose.
So many people have no idea what they bought.
The first sensor is a 12MPx Sony sensor (bottom one) that captures standard photos, in focus.
The second sensor is a 5MPx Samsung sensor (top one) that analyzes the whole frame and returns RAW depth data for the camera app to process, to bring a better blur effect for the portrait mode.
This is a bonus to the classic software portrait mode, it helps. It's not useless, and it's not for show off.
The fact that it doesn't work as good in dark environment is because the Samsung sensor is cheap and can't give enough data in darkness.
Now, let's see when both cameras work at the same time (not applicable on this device):
- when the secondary sensor is black and white, this helps the pictures get more dynamic range
- when the secondary sensor is the same as the other sensor, this is used for 3D imaging (chech HTC 3D)
Now when 2 modules work independently and can be switched via software:
- when the main lens are normal and the other lens are wide lens
- when the main lens are normal and the other lens are zoom lens
Now, our device doesn't fit in either of the above categories and the best way to use the Portrait mode is to use a ToF sensor, but baring in mind the price of our device the ToF sensor was replaced with a standard, low quality camera sensor from Samsung.

Note 10+ camera lens

My expectation when switching between the cameras in the standard photo mode, that each mode would use each sperate lens (1 lens per mode, 3 lens) but this is not the case. What is the bottom lens? Block it with your finger and no matter what setting you use, your finger will not actually block any use able camera. What actually is the lowest lens? What is it for? The s10+ has the same lens also.

Bottom lens is the telephoto lens. It is only used if there is enough light. If it thinks that you can get a better photo using a cropped image from the main sensor then it will use that instead.

Thank you! It's pretty hard to find any information on this.

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.
