How is the image quality between 2x-4.9x zoom? - Samsung Galaxy Note 20 Ultra Questions & Answers

Has anyone come across any detailed review / analysis of the main len's image quality when zoomed in? I'm a bit concerned it might not perform as well as other cameras that have a tele lens that starts at 2x or 3x optical zoom. The tele lens on the N20U doesn't kick in until 5x optical zoom (or I think there was a bug where it doesn't kick in until 10x zoom?)

It's a digital zoom. What do you think?

2x - so, so. 4x - clearly digital and pixelated (especially, when recording videos), 5x - great (both video and photo), 10x - very good, almost like optical, 20x - pixelated, not good for serious things, 50x - just for fun, pixelated artwork.
I m highly disappointed as I thought everything up to 5x should be optical. 5x is great but sometimes we just need 2x.
I am also disappointed in 108mpx camera as no optical zoom/ultrawide is available in this option plus image quality is worse than standard 12mpx camera. So not sure why Samsung did like this.
The same thing with video: we get ultrawide/optical zoom only in 30fps mode. No ultrawide/optical zoom in 60fps mode, only digital zoom, which is very disappointing.
However, putting these issues aside, both photo and video cameras are just great, pictures are crisp, quality is very good even during night time.
I wonder if it would be possible to unlock optical zoom/ultrawide with 60fps mode...

[Q] How does the Sensor-Zoom work?

Hi Guys,
I asked myself how the zoom on my Z3 should work.
As far as I know, the Z3 can Zoom into the sensor while taking 8mpix pictures.
While I tried it, it seemed to me that the quality gets really bad.
I was guessing that the indicator on the left is the indicator which separates digital zoom from the sensor-zoom.
As far as I thought the light grey indicator-bar shows the part which is the sensor zoom and the dark part is the digital zoom.
Considering the quality it seems to me that both modes are digital zoom. The picture looks really annoying while i use it.
I just thought maybe I'm doing something wrong - has anyone an idea how I can improve this or use it right or or or...
Regards,
Matthias
I didn't know about the 8mp restriction, i also tested it out in the shop, but in 20mp mode. The sections looked identical. However, as the sensor is not at it's limits at 8mp, i guess it could take a higher resolution and crop it to 8mp size at the zoomed in section.
Auto mode enables you to use the camera's Clear Zoom feature, which produces good-looking, lossless-like digital zoom.

the image is stretched by the software, which then attempts to fill in the blanks as best as it can. Well, thanks to the giant sensors on the Nokia Lumia 1020 and Sony Xperia Z1/Z1 Compact, zoom is no longer a problem. But instead of opting for bulky zoom lens (Galaxy S4 Zoom), they both rely on their massive resolution in order to get what we call 'lossless' zoom.
So what's lossless zoom, then? In simple terms, it means that zooming into a scene will only result in a negligible loss in quality. Think of it this way: there are so many pixels available with a camera like the one on the 1020 that you can 'crop' any part of the photo and still have more than enough pixels for a full-sized photo that will appear zoomed in. No upscaling, and no loss of quality. But how does it work in practice?

Okay, it is something like digital zoom. But I think, the quality while zooming into an 8mpix picture should not be worse in quality (depending on the zoom factor) than the 20mpix picture.
When I take a 8 mpix picture, I assume that the image processor will take it in 20mpix and shrink it down to 8.
And what I would like to see is that
I could zoom in and it will just move into the sensor to a 1:1 size.
Another thing : while using the video mode, the stabilizer does an amazing job.
What about the photo-mode? I can't see any stabilisation there.
Since I only take 8mpi pictures, I guess the picture-frame could also be panned around the 20m of the sensor...

In SA mode, phone take oversampled photo (which means he take 21mp, but he make HD pixel (one pixel combine colors from neibghours)... so when you take 8mpx it takes 20mp ovesampled.
When you zoom in, it will take more and more neibhours pixel to combine in one, so that means loseless.

How necessary is a telephoto camera?

I am wavering between buying an s10e or an s10. In favor of the s10e: I prefer the size of the device and I like that there is a slight bezel on the left and right of the screen. However, it doesn't have the telephoto camera. I found that zoomed photos with the telephoto on the s10 are quite a bit sharper. On the other hand, I seriously dislike the s10's infinity screen. It warps the egdes of photos, web pages, etc. So, it comes down to how much advantage the telephoto camera provides. If it's not so important, I'd opt for the s10e. I'd like to see some opinions about the necessity for the telephoto. BTW, I realize the P30 has 3 cameras and a flat screen, but it's not the horse I want to ride - no wireless charging, no IP68, so-so sound, probably even worse at updates the Sammy.
All depends what you want.
Yes, a dedicated zoom camera makes better zoom photos.
But, even with image stabilization it is harder to get good shots that are not blurry. I never used zoom on a phone. But i can tell you that since i have the S10e i do mostly 2 photos with the standard cam and than with wide angle. Wide angle does interesting photos.
It is good to have
I don't take photos all too frequently, and when I do I never use zoom. It degrades the quality of the image quite a bit, be it optical or digital.
Since asking this question, I took time at a local store to play with the 10 and 10e. I set both to 8x zoom, since that is the max zoom for the 10e. There is quite a noticeable difference. The 10e had lot of noise and the 10 didn't. In fact, at 10x, the 10 still had a clearer image than the 10e. Now, if I could just come to terms with the curved screen and the weird edge reflections.
Not at all to me but i wish samsung went for the same wide angle lens on huawei mate 20 pro, usable in close up shots and gets amazing photos.

I don't think it's that necessary... When you get 5x or 10x optical then it's cool, but 2x nah... I think the ultrawide is more fun
Getting a 10e here. But wondering how much worse the live focus will be without the Tele lens. Anyone have the experience?

Camera vs S10?

Any one able to compare the camera with the Samsung S10? Is it better or worse?
Having both phones, I can say it's worse.
The main issue really is the exposure and whatever HDR+ algorithm they're implementing in the stock camera app. Even though they said it's the same HRD algorithm that was applied by google for pixel phones, I still think it's over exposing everything especially the low tones and shadows - this produce a very unnatural looking picture. (If I wear a black shirt, my pic came out as if I'm wearing a gray shirt due to overexposure on the shadows).
On the other hand, I'm really loving the flip camera and the ability to use wide angle for selfie/group selfie and video. That is definitely the highlight of this hardware. But I will be lying if I say I'm not struggling to love the quality of the pictures produced by this phone.
Have you tried the GCAM port? for me it produces better pics...
The Asus stock camera is hit or miss. Too inconsistent for me, especially the HDR++ mode.
But with arnova's GCam port it is simply amazing and blows away even the pixel 3 cameras.
The wide angle camera in our Asus does not focus as good as the main camera ..try it..also the slow motion videos are not that sharp and crisp.

Agreed, that there is sometimes overexposure, but I like more Asus camera's bright photos instead of GCAM darker photos. GCAM is better in very dark, but I prefer Asus camera often, specially for low light photos. Well, I have exposure compensation + 0,4 in GCAM, but still ...
I can easy say that this is the best cellphone camera on the market now, I installed Gcam and activaed raw.
I have never seen a phonecamera produce such a good raw files, even in low light.
Skintones, natural colors is great on this camera, Samsung, Sony, Huawei. and lot of other manufactors are terrible when it comes to natural skintones, overuse of noisce reduction....
Also the 4K 60fps is very natural and doesn't have the unatural look that almost every other brand have.

Photo quality

Say "cheese", then rate this thread to express how photos taken with the OPPO Reno 10x Zoom come out. A higher rating indicates that photos offer rich color (without over-saturating), sharp detail (with all subjects in-focus), and appropriate exposure (with even lighting).
Then, drop a comment if you have anything to add!
Images are good but a little soft ..
Image/Photo quality
Oppo reno10x zoom
Camera
Image quality not good.....
Dynamic range is not good
No sharpness in images
Oppo Reno 10x zoom dont have metering mode in camera settings...
Artificial Intelligence is of no use...
Dear #oppo team stop cheating your customers....
Bad camera.......
I feel it performs well,with higher pixels,and clearer.
Great Camera Hardware, still needs improvements in image processing
Reno 10x got a very good hardware in its camera department. The photos are also good and feels nice. However the images needs better processing, especially the HDR shots. Thank you.
Huge focus hunting issue in lowlight,worst camera app...
My last phone was the Xiaomi Mi Note 10 Pro with a very good camera. Now i´ve bought The Reno 10x and in comparison the photos with the 10x are in the most situations muchg better than Xiaomis photos. Especially the zoom function is more effective. I´m very satisfied with this device. Photos are sharp, many details, with Color OS 7.1 i can use the zoom function also in video mode - with Xiaomi this is a big problem. And the device offers 5G and a much faster processor than Xiaomis model.
Photo quality is it's quite good considering it's price tag. If you compare this smartphone to the typical samsung, iphone, huawei flagships of course you may conclude that the camera is not good at all.
Color tones are inclined to "natural", not like Samsung cameras that tends to make over saturated photos.
Main camera:
Lacks a bit of detail and color deph. At 48mp mode detail improves but zoom, hdr, color dazzle options are nulled.
Night mode gives vivid colors but are blurry. To countermeasure this issue I use Gcam or "Manual mode" in the default cam (long exposure at 100 ISO).
Telephoto lens:
Photos zoomed up until 4.9x are digitally zoomed. Then optical 5x zoom kicks in. Zooming higher than 5x makes blurry grainy photos. For this reason I only use 1~2x or 5x. Colors lack a saturation but can be improved with "hdr" and "dazzle color". Or by using Gcam.
Wide lens:
Makes photos with noticeable color aberrations lacking even more detail than main lens, but still makes much better photos than using these cheap attachable wide lens.
Macro:
Strangely the wide lens is suggested for macro but I think the main lens is more suitable due to higher image detail. Closest focus distance of main lens is approximately 8cm so you cannot take very close-up photos. But by buying these cheap small attachable lens you can make good macro photos.
Coming from a single lens smartphone, I'm very happy with the Oppo Reno 10x zoom as it can cover almost all camera modes. Zoom, ultra-wide, macro (by using attachable lens), manual mode, RAW(Gcam), astrophotography(Gcam), 4k 60fps, etc. I'm only disappointed at how sometimes the images lacks deepness.

Question Camera and Video Recording questions

So far liking the new 7p, havent seen any crazy battery drain or anything yet.
Camera can shoot 30x pics but only 20x video... any idea why? Tried changing settings (1080p, 30fps) to no avail.
Wonder why we cant shoot HDR in 60fps either...
Can the 6p do these?
Thanks
Likely due to lack of light and/or processing power. The 7 Pro uses the telephoto lens that can do 5x and 10x with a 1:1 crop. Everything between or beyond those steps get processed with data from the main sensor and the new Super Resolution AI. Considering it can do 30x for a single frame. Mediocre 20x for 30/60fps is seems fine for video.
I am also miffed about not having HDR at 60fps especially since we can now do full zoom on FHD/UHD unlike the 6 Pro getting locked out of 60fps for UHD 4x zoom.
