I am an avid photographer. I used to use a Canon DSLR for most of my photography (of antique/classic car shows, macro/flowers). Since getting my Note 10+ last year, it has been my primary/go-to camera. From general photograpy to macro/up-close, it has done a fantasic job. Folks rave about the photos I take with it. Yes, sometimes the focus hunted and sometimes it was aggravating by focusing on the wrong part of the image I was trying to take, and yes distance photograpy was lacking a bit. I took a 2-week driving vacation and never used my DSLR and almost every shot (over 3,000) is a keeper.
With all of the talk about the new cameras in the Note 20 Ultra, I ordered one. It arrived yesterday/Wednesday.
After getting it fully running/charged/patched, I went outside (bright and sunny) and took some up-close shots of flowers. The results were garbage. Totally unusable/out-of-focus/over-blown. Using the default 108MP is useless (takes at least a second to save/store the image from the time I pressed the shutter button). Even dropping back to the 12MP lens (which is slightly less resoluton than the 10+), the results were unusable.
Later in the evening, I decided to try it again in a more controlled environment. I propped both phones the same way (to remove hand-shake) and took the same shot with both phones (see below - unfortunately, this site would not let me upload the 108MP version of this shot due to size).
So, unless someone can tell me that I am "simply doing it wrong" (can't imaging what that could be) or "change this setting" or "you got a bad one - here are some shots I took with mine", I am ready to send it back to Samsung and say forget-it - not worth it!
That much of a focus difference is the depth-of-field, i.e. an f/2.8 lens will show more of the object in focus than a f/1.8. But spec-wise, the primary camera aperature in the N10+ and N20U should be the same. it's not just the examples I posted. The ones I took outdoors were completely out-of-focus. Here are some more examples I just took a few minutes ago...
Since the 108MP version can not be uploaded here (10MB), here is a link in Google Photos: https://photos.app.goo.gl/NpM4wTAfw32EaULG7
As you can see, it is even worse. Also, FWIW, I am using the s-pen to take the shots/reduce screen movement...
Nice sample photos - your flower shot (taken by the Note 10+) is gorgeous. However, yes, I am experiencing the same focus issues as you. Not so much the erratic focus or overexposure, but the fact that the Note 20 has a larger sensor and NO dual aperture like the Note 10 series, all my close-up shots exhibit "focus fringing" where there seems to be more of a pinpoint focus with much of the outer areas out of focus. It's partially explained in NothingButTech's YouTube video at 4:27.
My sample shots are of my dashboard - the first (brighter picture) is with the settings on Auto. As you can see, the center is in focus; however, the outer areas are not - specifically see the "4" in the tachometer and any number from 80 mph on in the speedometer. The second picture was taken in Pro mode, and I ratcheted up the shutter speed, and it helped ever so slightly. Why Samsung got rid of the dual (or variable) aperture on the Note flagship is a mystery - probably the same reason they went from a 5000 mAh battery on the S20U to a 4500 mAh battery on the Note 20U (true head-scratcher there). I'm no pro photog, but it's disappointing to see that we can't take close-ups (let alone macro shots) with a $1300 phone camera without a nice, sharp, focused image throughout the shot, if that's what we desire for the picture. Looks like I'll be using my wife's aging S10 to take those shots!
Can this be fixed with a software update? Maybe and hopefully! Perhaps one of the nice friendly Samsung Care Ambassadors will read this thread and comment further.
Since my post I have been playing with it and doing some research. One place discussing similar issues with the S20 talked about "go into pro mode and manually focus"? Another way I found was to force AF/AE Lock in the regular photo mode and then force it to focus where you want. However, to do that you have to be in 12MP mode, not the 108MP mode which then makes the 108MP somewhat useless since I now pretty much leave it in the 12MP mode.
With the 10+, I simply pressed the .5X zoom button and shot the photo. Easy-Peesy.....
While I was able to get some decent shots using these methods (see attached samples), it defeats the whole purpose of being automatic focus. But after spending a day using the 20ULT for what I use the 10+, it was an exhausting, frustrating shoot. See my post here: Note 20 Ultra Photograpy/Camera Issues
At this point, I am at the verge of sending it back.
Again - beautiful pictures with artsy bokeh. But I can't help but wonder if, in the second picture, i wanted the entire flower, including the distant petals, to be more in focus, that would allow the flower to pop even more!
Alas, you have come up with some workarounds that might help, might not, because if you select focus on those distant petals, perhaps the pistel of the flower would then be out of focus...? That would be an "Arg" moment for sure. I tried out your focus selection workaround on my dashboard, and it does work for the most part, but again, it's a hope and a wish that Samsung can somehow push and update with a software-based algorithm that mimicks a variable aperture for shots that you want a wider field of focus.
I've heard debates back and forth that the pixel binning for the 12MP setting is actually sharper than the full out 108MP shots, and since I'm not blowing any of my images up to poster size, I'm sticking with the 12MP normal mode.
Good luck with your decision to return the 20U. I'm at the point of no return (literally), as I've already sent my Note 8 in as part of the Trade In program. The best I could hope for is that my unit is faulty and I would exchange it for a better unit. However, I think the "focus fringing" that I'm complaining about is a "feature" of these larger sensors.
I'll go read your other thread now...
Thanks. I did not force the bokeh - it did that itself since it choose an f/1.8 aperature. The way to choose your focus points is the press-and-hold on the image itself and 2-circles will show up - which you can drag/separate (I did this in the first photo with 2-yellow flowers by dragging the AF circle to the left side/darker center) to where ever you want to choose the focus (AF) and/or exposure (AE) locations for it to use. Otherwise, in PRO mode, you can simply choose Manual Focus and drag that slider to the focus/sharpness you want.
I thought the aperture was fixed at f/1.8 on the 20U, so it can't choose a smaller aperture for a wider focus scope.
How do you get the 2 circles to show up? When I'm on Auto (PHOTO), if I press and hold the screen, the yellow circle of the AF/AE lock gets set and no other circles come up. If I press in 2 different places, it goes into zoom mode.
My bad. The separation of AF/AE only seems to occur in PRO mode, which I am accidently switching to when I don't mean to (another annoyance of the 20U).
F/1.8 is the widest and gives you the most light but causes the bokeh. But I think it will vary based on the camera/natural light. For example, the photo I am attaching shows an F/3. Not sure if the metadata is included when you attach a photo here - here it is in Google Photos: https://photos.app.goo.gl/DS5RXpKDNherevH79
