Optical Image Stabilization? - Essential Phone Questions & Answers

Will this phone omit OIS? I don't see it listed on the spec sheet.

I remember reading in their Q&A section that it's only digital.

I could be wrong, but I don't think OIS is possible with this kind of dual-camera setup. Somebody else can feel free to correct me.

They said on Twitter a while ago that it will have EIS, based on the gyroscope in the phone (like the Pixel).

Post :Your best found Cam settings for clarity

Here's the deal, I'm curious to know what ...peoples best found camera settings/ tweaks for the best clarity on ranging from "moderate distance , to up close shots ".
I had the HTC one initially and fell for the camera day one, then ended up getting a s4 I had for a week ..and I really enjoyed the extreme clarity as far as detailed focus was concerned on up close pics when I say upclose I mean anything within 10 inches of the camera focused any blurr right out into clarity . While the s4 seemed to focus Into detail ,the HTC one seems to struggle just a bit.
All in all I returned to the htc one as I like it more ... for many other reasons .
So who has some specific One cam settings to share ,that have been found to be perfect thru trial and error.

There are no "perfect" settings. Everybody sees different things in a photo and from a previous thread I saw, variants were very different on the setup of the camera. The way I see it is this, play with the settings and settle on what looks best to you. forget what anybody else suggests because it's only what you think that matters ..... Personally I have mine setup as it came, default on everything and I'm more than happy with the quality of the pictures.
- The HTC One has a large sensor
- Large sensors produce "shallow depth of field"

Regardless of sensor size, depth of field is dictated by the aperture and not sensor size. Bokeh is more apparent with a wider aperture (faster). The HTC One sensor is exactly the same size as every other camera sensor in high end Android devices.
Personally for me I use -1 Sharpness and +1 Contrast.
Ok I'll agree with you I guess- it's a large "opening" where the light goes in. Large aperture. Fine.
A large aperture does cause shallower depth of field.
I guess that article just says there's multiple things that go into determining how deep your focus will be and *all other things being equal* larger sensor size changes the geometry in a way that generally decreases depth of field.
To spell this out for everyone one more time: In an image portraying many objects of widely varying distances from the camera, it helps draw attention to the objects that the camera locked focus on by increasing the likelihood that other objects will be out of focus. This is often desirable. The OP of this thread apparently was in a situation where he did not find it desirable, but that is not necessarily a *defect* of the camera, just a design decision.

Nexus 6 and Camera FV-5 discussion

So I wanted to make this thread for photo buffs (as much as you can be on a smartphone lol) and newbs to get together to discuss best settings in this app for different situations. FV-5, as most of you probably know, basically takes L Camera to a new level w/ a much nicer GUI (of course, you have to pay in the google play store for it). they do have a lite version as well for you to test out. But it allows you to shoot in RAW and control pretty much every aspect of your camera.
For those of you not aware, here is the user manual.
* I may have posted this in the wrong section and it should have gone in the app section, if so mods please move
I use this app next to manual camera and I must say this one is the better one fo the two.
It's just not that much of a hussle to use.

LG G4 Bad OIS

Looks like the G4's OIS is too aggressive and the videos taken look shaky.
Is this something future G4 owners will have to live with or can this be fixed by a software update, or perhaps a third party camera app?

I think LG depends too much on the OIS. OIS should work with DIS, not be an either-or situation.
The OIS in the G4 has more travel than the S6, which means it wants to stabilize the picture when the camera is moving during video and then snaps back more when it hits the end of the travel. The net result is, paradoxically, shakier video when the camera is moving around. This issue with video and OIS was pointed out in the Anandtech review of the S6, and was considered the probable reason that the iPhone 6+ disables OIS for video and uses only EIS.
I haven't tried it, but I've read that using EIS in conjunction with OIS on the S6 causes the video the pitch all over the place. Since OIS can't be disabled, it was recommended to disable EIS.
Technically, the OIS in the G4 is OIS 2.0 as they added another axis.
Yeah, that does not look good.
Yes, a software update can chill out the censors activities. The hardware is not just independently acting on it's own.
Umm....Those videos were taken at 1080p....not UHD setting. Not sure how that affects OIS.
All I can say is that my G3 takes very steady video on UHD...nothing as shaky or warping like as that video showed for the G4. I can't imagine LG screwing up so badly with the G4. I really want the G4 because of its better contrast screen(once thing I always found annoying is that the G3 always looked a bit grey/washed out compared to OLED screens). I will be looking to get the G4 full price, not on contract....so really hope this OIS thing gets sorted out.
Quite frankly, the OIS issue isn't really a big deal unless you really like taking video while walking around. For typical video shooting, OIS helps way more than it hurts.
Keep in mind these are early G4's with a non final firmware.
On the other hand if you send reviewers a G4 better have the OIS fixed.
Let's hope it will be not that bad.
The conclusions are too early.
The person who posted an another video of speed test said that this is not a review unit, It is a consumer unit which all consumers will use in comments when someone asked
Ha love the idea of quoting one early review and then stating it is fact and gospel. Ridiculous.
I am buying it. No matter what is OIS doing. It's better with it then without. I can't understand why we even talking about something that is hitting the shelves at the end of the month [ here in Europe ].
I use my G3 for video very heavily. (got over 2tb of videos from it and its only been almost a year since I got it.) None of my vids are that janky as in those review videos.
Just have to wait until the G4 is out for a while...see what happens.

Yes I've had the g4 since last Tuesday - got it from a work mate in South Korea - and my videos look fine.
Silly LG ! why don't LG just use common sense? if they give unstable, unreliable and unfinished phone or software version phone to people for try they will publish and talk about all it deficiency, problem and other bad things, most of people publish video, opinion and review based on this initial hardware and software, so instead of promotion LG is actually damage his image and product and ruin the successful flagship launch by doing it, also LG need to understand that when they give phone to thousands of people to try give them a best looking phone instead of just giving plastic version to every tester or reviewer, do you thing any tester or reviewer can impress their friends or family by showed this unimpressive plastic version???
One thing I will say, I just did a video testing myself with my G4. The video was a little shaky then what I thought was recorded but what did annoy me was in auto mode the focusing was just horrible.
This camera software is definitely not finished

Usually OIS can be disabled through build.prop
upload this file found here system/lib/hw/camera.msm8xxx.so
i will find what needs to be added to build.prop to disable ois

Maybe we should disable OIS and try to figure out a way to have DIS.
And on this review they say it has better stabilisation?
Lbs has a faulty device?

Would there be any way to disable OIS on a G3? Sorry to go a bit off topic with my question but this thread is the only one I could find anywhere on the web mentioning the possibility if disabling OIS on an LG phone.
I use my phone as a dash cam when driving my car on race tracks. OIS give a wavey distortion due to the various G forces encountered.
Defcomg, will a solution for the G4 work on a G3?
Upload camera.MSM8974.so from g3 I will find the build.prop property needed to disable ois

Edit:
Here are the OIS Control params they can be added to an opensource camera app such as a better camera/opencamera/freedcam
Key
Code:
"ois-ctrl"
Values
Code:
"preview-capture","capture","video","centering-only","centering-off"
this is from a g2 pro lib but it was the same in g3 lib not sure if it applies to g4
Thanks defcomg for a quick reply. I don't see any access to system/lib/hw/camera. I'm going to bet my phone needs to be rooted. I can give that a go but it may take a while for me to learn how. Sorry I'm a low level user. And Verizon is pounding me to update to Lollipop which I have been hesitant to do. (I read lots of complaints about battery degradation and wi-fi issues.) I should probably go ahead and do that in case doing it later unroots the phone.

Info on the Z5's camera system

I found this a few weeks ago while looking for details on the new fangled closed-loop actuator. It was from a presentation given by Sony in Taiwan. It's in Chinese (use Google Translate), but the slides are in English.

The closed-loop actuator should be just used to detect the motion direction for the video software stabilization, not really acting like an OIS to actively cancel the vibration.

It definitely cancels vibrations. Check out this video. The dash of the car is vibrating like nuts, but the video is buttery smooth.
https://www.youtube.com/watch?v=ylKufshZ698
What's not clear is whether the actuator is being used to stabilize picture taking. The only thing I've read is that the actuator helps make the auto-focus faster and more accurate for pics. I assume if it were software-only, then the frame would be cropped, and the border would be used to "adjust" the image. I don't think that's the case... could Z5 owners verify?
I believe Timaustin2000 said that SteadyShot doesn't work in 23/20 MP manual mode (please correct me if I'm wrong), which would lead me to believe it is disabled for 23/20 MP SA as well. That would explain why some pics look "smudged" in 23/20 MP.
Any Z5 owner want to comment on how SteadyShot is working for pics?

The video enabled the Intelligent Active Mode for software video stabilization which helps from the actuator but isn't an OIS still because it does cut the FOV. If it is a truely OIS, Sony will advertise it. Actuator isn't any new stuffs. Sony been used such actuator for a long long time in some old DV tape camcorderor small FHD camcorder like TG1(which I had one).

As a result, the volume of entire optical system including the actuator is significantly reduced, namely "a 75% reduction from the existing models," according to Osano.
The steadyshot won't actually work for photo bcoz both 23MP/8MP got the same FOV. The actuator is mainly designed for detect the direction and hence, might got a bit helpful for video focusing as well.

Ah yes, you're right. I remember seeing that the FOV is narrower when taking video, hence the "hybrid" stabilization. But it still doesn't clarify what SteadyShot does for pics. I had assumed the actuator system was derived from the Alpha series, which is sensor-based, but it might not be the case. Looking at the block diagram, the actuator sits above the sensor, nor does it use a floating lens of a traditional OIS system.
It looks to me that the actuator is used as a shock/shake suppressor rather than precise lens compensation. Not enough info to go on.

Sony said they are considering to implement OIS in next year. The actuator comes with the Z5 lens but the Sony TG1 actuator is also located in the optical system. It needs some of shock/sharke suppressor to calculating the direction but if it is an OIS, it actually need a much larger space for the lens or sensor to "move". On my S6, I can see my lens moving on the back, it is a lens-shift based OIS.

FIRST OnePlus 5T camera review by heise.de!

https://m.heise.de/ct/artikel/OnePlus-5T-Keine-Zoom-Kamera-mehr-3887487.html
Heise.de is one very serious german tech site and they say that since other sites already broke the NDA they dont feel obliged to hold information back.
To make it short: camera does not get better, low light performance gets even worse.
Long version: The camera setup (still WITHOUT OIS!) will be 16+20 mp again BUT the 20 mp sensor this time won't work as telephoto lens. Also aperture changes from f/2.6 to also f/1.7 like the 16 mp main snapper. Pixel size of the 20 mp sensor stays at 1.0 um. This sensor will, despite its crazily small pixel size, automatically work as low light shooter when light levels drop below 3.5 lux, making pictures look even worse than with the 16 mp sensor.
The Software does NOT use both sensors to combine the picture information like it is the case for other phones. Thus, picture quality does not seem to improve compared to the OP 5.
My comment: This really doesnt seem to make any sense. Why not put in a sensor with bigger pixels if you want a lowlight specific unit? Why take one with even smaller pixels? Wtf!? Did they have too many of those crappy 20mp sensor left over? Or why not at least use both sensors to combine the two die pics? Or why not just use the fabulous sensor that the s8/pixel2 uses and put an OIS in it? This is so stupid oneplus, i just dont get it..
Furthermore: Usb will again be 2.0.
2015 all over again..
What do you think?

This is OP5 forum, there is a OP5T forum.
Sorry, didnt see there was a 5t forum already. I posted it there, pls delete this thread, thx.
