How many elements, one?
Anti-reflective coating?
It looks like an optical mess... no blur or CA charts which would probably scare you off fast.

Looks very similar to the Ulanzi lens here:
Neither great nor terrible - but indeed, closer to terrible...

I've shot with Canon L lens, the 70-200 f/2.8 IS was a particular favorite. Sublime when shot wide open, it could grab almost any shot.
I have a N10+ and for what it is it does very good.
If you start trying to add on lens though the image quality will quickly drop. They aren't design to be used like this, the attachment interface as well as the optic matching (or lack of) and that case lense protector would turn it into an abortion. You can get grab images but the quality will suffer.
Best advise; shoot within the limits of your existing cam/lense.
The 70-200 shooting into the setting sun wide open, what street shooter this beast is.

Camera 360 works much better then stock cam software.

So I took some pics with different settings in Camera 360 program. I forgot what the settings I selected were but its pretty much all of them.

This was all done on the phone. No computer side processing.
Oh P.S. these are all seprate pics of the same thing.
better because it has some extra filters?
take some long distance shots with the default camera app, then take the same shot with camera 360, and we'll see which picture looks sharper.

Yeah, I've taken pictures just as good of close-up flowers with the stock camera app. Those look great though! The camera is pretty excellent on the Captivate IMO.
Some of those filters look fantastic!!
/downloading camera360
for some reason i find that my camera is sub-par.. pictures always come out blurry even though i am very steady. i will try camera 360 and hopefully it will help
So what color is the flower supposed to be? Purple or Red. I'd say that only one of those photos looks good. I think the one where its red looks good, the leaves look a good solid green. The rest look kind of like "neon" lights or something.
I find that my Touch Pro w/ it's 3.2MP camera takes sharper photos than the captivate does indoors. I have a 30" monitor so I can actually verify if the camera is keeping up with the horizontal resolution of 2560. I would rate the effective pixel resolution only at like 2.5MP for the captivate. I would say the rest of the 2.5MP seem extrapolated w/ noise.
While YellowGTO's shots look good, we must remember that they are downsized. I tried out camera 360 as well. But imo that application only applies some digital filters to beef up the picture - I can do this w/ picasa. In the end TP's shots blow those of captivate to dust. Captivate lacks refinement.
Engadget did say that the camera quality is better on the vibrant than it is in the captivate. It would be nice if someone who also has access to the vibrant or the i9000 can compare the refinement abilities.
looks awesome!!!
Does this app let you use the camera on a low battery (unlike the stock)?
Those all look severly over saturated to my eye.

Which is one of the main advantages of this program. I also like Fxcamera, though the pictures quality looks far worse on the computer than when viewed on the phone.

HDR Mode?
I have noticed the same thing even in some daytime shots. Usually when there is a bright source of light in front of the camera (unfortunately, can't upload from work due to network restrictions). Do you have the HDR mode set to On or Auto?
That's called lense flair. It's cause by the glass on the camera cover.
That's normal on wide lenses. Lenses on dslr comes with Lens hood to prevent flare but all wide lenses has a more or less degree of flare. You should try to use your hand as a lens hood to prevent light from corners to reach the lens. Some photographers use flare as an artistic effect... so just try to compose your photos to avoid marginal strong light and use your hand to block strong light to reach your lens

HDR auto, first noticed this issue.
I've had this issuse on my S7 Edge and on all my S8+ (5 units).
I've also tested my friend's S7 and it also happens.
It's a technology problem not a deffect. Even DSLR suffer from this.

Some questions about the P40 Pro’s camera settings

Hello, I am interested in buying the P40 Pro. I know that the P40 pro shoots at 12.5 MP by default, but to do this, there is some upscaling. In theory this would result in worse pictures than the Mate 30 Pro. Would it be possible to shoot at a non-scaled resolution, such as 10mp as was the default of prior Huawei flagships, and prevent the upscaling? Thanks
There is no upscaling, there's downscaling.
Main camera provides 50 MP, just devide it by 4 - and you're at 12,5 MP.
So your fears about losses caused by upscaling are quite baseless.
Picture quality is real great, just the Pro mode is close to useless, yet.
Yep, P40P uses 4-in-1 pixel binning to output 12.5MP shots from its 50MP main sensor (50/4=12.5)
I was getting terrible photos versus my previous M30P but after all these firmware updates recently, can safely say it's much better now imo.
ignore post
Gsmarena just published the review on the P40 Pro +. The image from the primary is indeed cropped. Only when users shoot at 50mp or at .85 zoom, you can see the uncropped image. This means that the image is indeed being up-scaled by around 20 percent. I don't understand why they just didn't keep it at 10.5MP to prevent this upscaling. Some Huawei phones allow you to shoot at different MPs, does this phone allowed any other image sizes besides the 12.5mp and 50mp while still maintaining aspect ratio?

^Default 12.5mp images
Shot at .85 zoom which removes the crop.
Thanks so much!
. 85x zoom is not through their ultra wide sensor?

I don't think so, in any case, when you shoot a 1x zoom at 50mp, and then 1x zoom at 12.5mp, the 12.5mp image is still cropped. About 20% of the image is cropped off, that means Huawei is doing some upscaling. I don't care about the image being cropped, the edges of most cellphone cameras are pretty much crap anyways, but I don't think they should upscale it.

Question macro camera shots?

i'm looking for a phone with a good macro camera to view and take shots of PCB surface mount components. (resistors etc)
looking at the Moto G Stylus G5 since it's macro camera is 5MP. however none of the reviews i've seen include macro shots.
dear reviewers... just because YOU don't have a need for a macro camera, don't assume it's the same for others.
can some owners be kind enough to post some macro shots please?
the closer to an object the better.
A little late but the moto g stylus 5g (original quad lens model) has awful macro shots so hopefully you were able to find something else.
The main rear camera quality is pretty decent at least.
The issue is with the dedicated macro lens, it's really hard to get a good focus on your subject since the lens is fixed focus, so no tap to focus. It's kind of boggling to be honest. I ended up just never using macro mode on the phone and use the main rear cam lens for close up shots.

many thanks for the info. i've ended up using an old Galaxy S5 (not as a phone) which does a good job at close work.
i can clearly read the surface mount resistor 18R0 (18Ω)

i may break down and get a dedicated macro image device as i'm getting tired of trying to find 'the one' ungoogled phone.
thanks again. cheers

Question Terrible front camera performance (Colour balance + Saturation)

Hi,
I was wondering if anyone else experienced this, I quite often make pictures with my front cam and the camera is such a downgrade from my 4 year old Xiaomi Mix 3! The colour balance is all off, almost like they forgot to make a profile for the front cam.
The back camera is just fine, but the front camera often looks like a $20 toy camera just because of this terrible colour balance. I can fix most of my selfies in Google Photos by using a combination of adding warmth (Colour Balance) and adding saturation which makes them look just fine.
For a phone this expensive... this shouldn't be needed. I'd say most mid-level phones even make better selfies then this.
I've tried cleaning the lens but this makes no difference, the Samsung camera app just fails to properly process the colours in the front camera's images.
Because I apparently don't value my privacy, here is a picture as taken by the Samsung camera, and the same picture after adding warmth and saturation.
The original image makes me look lifeless with the skin being very pale, like a zombie almost. It was a nice and sunny day, why do I look like I'm 10 seconds away from my death?

Anyone else with this issue? Does a modded version of the Samsung camera exist with the possibility to manually define post-processing settings? I just need to have it add more saturation and offset the colour balance
I'm searching for a solution myself, google's Gcam camera is great but I can't find a way to make it use the front camera. I'll be back if I find a way..

I've searched high and wide for a way to make another camera app the default one to get a better front camera selfie (even by disabling Samsung camera) but it seems like the cover screen and Samsung camera are intertwined and cannot be separated.
What we really need is a developer to have a look at the system framework or whatnot and see if something can be done to change the default camera, but they (developers) are a rare breed nowadays.
But on the bright side, if they ever do a remake of the movie weekend at Bernie's I'm pretty sure they'd offer you a part with photos like that..!
