Helo everybody,
I am wondering if there is a way to lock F2.4 lens with 2x zoom no matter lighting conditions? I am so frustrated when we get digital zoom instead of 2x optical zoom because of bad (under 100 lux) in worse than optimal light. It's F2.4 optical stablised lens so why digital zoom? That sucks don't you think..?
honestly, you'll be surprised on how bad the tele lens in capturing light.
You can play with this. Go to live focus mode, turn the blur effect all the way down. This will force the tele lens to be used. Make sure dual capture is ON.
Now go to your gallery and find that pic, compare the picture in Close up Vs. Wide. You'll be surprised on the difference between the two lens.
What boggled me more is the fact that the tele lens is the one that they used for the Slomo mode. You would think that they would use the main lens with brighter aperture for something that requires soooo much light.

It seems like the camcorder is much higher quality, seems odd, since it's coming from the same lens. Even just switching between the two, the camcorder doesn't have as much viewing angle, and everything seems much sharper.
Anyone else notice this?
I have noticed it.
Wider angle = more in the picture = lower quality.
It's the same 5mp camera for both the camcorder and camera but since the camera has a wider viewing angle, more is in the picture at once and it decreases the relative resolution.
Unsure how it has a wider viewing angle, it is the same hardware.
My camcorder video always comes out looking nicer than my photos, even after I lower the resolution on the photos to 1280x720 after the picture is taken. The camera should natively look nicer on the small screen, since it's a larger resolution snapshot.
You probably just aren't holding the phone as still as you think you are. Try resting it on something stable when you are taking pictures if possible. Also, make sure you are holding down the shutter button to focus before you let go.
Done this, camera appears more blurry on the display even before taking a picture. Camcorder appears much more sharp and vivid.

The camera does not have a fixed lens, it can focus and zoom. When the camera is being used, the lens is at it's widest angle possible. Since the camcorder would not be able to process that wide of a video fast enough in 720p, the lens has a shorter viewing angle (aka wider focal length).
I'm big in photography so I'm speaking from knowledge of cameras and it may or may not be the same on cell hpones...but I'm pretty sure it is.

Partially correct, the camera physically moves to focus, but it's not changing the viewing angle. http://www.newscaletech.com/phone_camera.html
The resolution is changed within the app, it just crops the image. Camcorder is just likely sampling at a higher rate so there's less noise, and the stock camera app on the atrix is terrible.

The term "fixed lens" is ambiguous, since it doesn't specify which aspect is "fixed."
The Atrix camera module has a fixed focal length lens (i.e. not a zoom lens), but it is not a fixed focus lens (i.e. it has variable focus, in this case autofocus). The "zoom" function is just digital zoom, electronically cropping the image.
In video capture mode, the camera is cropping a section of the sensor, rather than using its full area as in still camera mode. (This increases the apparent focal length of the lens, but it's not actually changing the optics.) The video mode probably does this so that the resolution in the portion of the sensor used is a regular multiple of the video capture resolution, which can greatly simplify the image processing requirements.
Regarding the OP's original question, the viewfinder image appears sharper in video capture mode, but if you actually capture still and video images of the same scene, the still images are sharper. The better looking viewfinder in video mode is probably a result of the same reason they only use a cropped section of the sensor. It's like if you view an image in Photoshop at 25% size, it looks great because it's easy to scale the pixels that way, but if you view it at some usual magnification like 43%, it looks fuzzy.
Hi
Do you think it was possible to produce the same bokeh effect that iPhone 7 with wide Lens ?
Thx
Manual mode and take a macro shot? We do have manual focus mode so i guess you could recreate it
Its différent because iPhone use two Lens at time to create this effect (like Huawei p9?) And actually lg cant use Lens at same time to add more luminosity
Its a Big difference.
No, it's software processing not real bokeh. It may use the other camera to calculate distance so the software is more accurate but that's it. It's physically impossible such small sensor and lens to produce natural bokeh unless the subject is in macro range.
Hello,
i take photos from the night sky since serveral years (with smartphones too).
Unfortunately with the Samsung S9plus the stars are not pinpoint like as they are on the Samsung S7. They apear very distorted with a kind of a halo.
Ofcourse the smartphone was not moved during 10 seconds of exposure time.
I did layed it down and used the self timer mode to prevent shaking.
I tried it serveral days in comparison with the Samung S7.
The S7 is always much better and show pinpoint like stars.
The distortion of the stars is visible in the RAW files(DNG) too so no jpeg problem forced by the compression.
Could you reproduce the same problems?
I am not allowed to post links.So how to show you the photo?
Could send you the link of the uploaded photos for comparison.
The dual camera variants of Samsung phones tend to overexpose shots, especially during darker environment.
That's what I noticed, and I'm waiting for the update they sent to Note 9s.

Are you using the telephoto camera? It has OIS driven by digital gyroscopes. Those gyroscopes aren't effective at low frequencies so the OIS will slowly drift around a small amount. 1/5 second is usually the limit for sharp photos. Even when the gyroscopes are turned off, OIS lenses are VERY sensitive to motion because of the lens being on a soft suspension. Walking next to the tripod could wobble the lens.
You also can't expect clear images if you use F/1.5.
Try using the wide angle lens.
I would send a photo to someone of you so you can post it here into the Tread.
Who like to do it?
The camera was layed down on the ground so no shaking or vibration ppossible during the exposure time.
I found no setting that the OIS gyroscope is working in photo mode. OIS is probably only working in video modes.
Even if it works in photo mode, the camera was layed down, so no shaking could happen.
Who of you could make a photo from the stars with the following settings?
Pro Mode
Camera mounted or layed on the ground with direction to the night sky.
Self timer to prevent shaking
Iso 800
10sec shutter speed
F 1.4

Antwort unfortunately the tele lens only works in very good light conditions.
Even in a bright lighted room there is no way to activate the real Tele lens. The camera automatic switch to digital Zoom.
Also in pro mode its not possible to use the telephoto lens if the light condirions are not perfect.
This is very bad because if the cameras is standing still completely and the object doesn't move why not using the Tele camera lens in pro mode?
Very interesting Thanks for the link

Hej guys, I was wondering if my Mate has a problem with its lenses. As far as I understand it, there are three different lenses for wide, normal and zoom. The zoom lens is supposed to be the one under the flash.
But I can't activate that lens. Yes, I can zoom 3x, 5x. But the picture still comes from the normal lens, which I found out by putting something in front of the lenses to see which one blacks out. The lens under the flash is just never used, no matter what zoom setting I choose. So it seems like the zoom images are taken with the normal lens and digital zoom instead of the zoom lens.
Am I missing something? What do I have to do to activate the zoom lens ?
I just noticed that my 2x lens is not enabled under some circumstances, covered with my finger the middle lens (2x) to confirm, and you can still use normally the 2x zoom option in auto mode, it seems it doesn't switch to the 2x lens, and just zoom in the main camera.
In service mode all lens are are working as intended.
EDIT: it seems this occurs only in certain conditions like low light situations
It's just with auto trigger (auto mode using zoom).
Sent from my Sony Xperia 1!
This is normal and happens with most phones with more than one camera.
If you cover the 2x lens before switching to it and then you try to zoom in, it will detect that the lens is covered, so it will only zoom in the main camera lens.
Furthermore, if you switch to the 2x lens in low light (below 100 lux of brightness), the 2x lens will not be used and it will continue using the main lens.
