What is the minimum focus distance of the wide lens and the telephoto lens? - Huawei P40 Pro Questions & Answers

Just curious to get a estimation for how good macro photo's can look on the p40 pro, so im wondering about how much minimum distance is required for these two lenses to have a object in full focus.
does anyone know or can check?

10cm and you can use x3.5 zoom and still looks like macro without loose quality.

Hard to do screen with knock to get still sharp screen

what about the telephoto lens? perhaps you can make even better macro's with it.

I mailed huawei, they say for the p40 pro+ it is 240mm for the telephoto lens as the minimum focus distance.
I am very much doubting that this is correct haha.

Best photo resolution

Hi everyone!
Which resolution do you use, 12 mpx or 20 mpx? 12mpx gives you hybrid zoom x2 but phone only uses rgb lens, while 20mpx supposedly uses both lenses to create a hybrid colour/b&w pic. So which do you use? I have it on 12mpx in order to use zoom but don't really know which is best.
Cheers!
It actually depends on your preference and the situation you want to create in the photo. I use the 20mp when shooting wide angle landscapes, while im using the 12mp when shooting portraits or closeups

Thanks for replying! I've actually found that shooting a normal close up pic on 12mpx shoots in kind of a wide-angle effect. Last friday celebrating carnival at school, I was able to fit in a whole class of 28 kids from a few feet away. If u look at the pic, it looks like it has been shot on a wide-angle lens!
Any more opinions on camera config are more than welcome!
I don't believe that the 20MPx option uses both cameras. When you partially cover the B&W sensor, there is no noticable effect on the photo. Looks like it is only software based up-scaling and may get you jagged edges sometimes. After some testing with 20MPx and then 20MPx resized to 12MPx just for comparison, I prefer the 12MPx default setting.

Hi Marian, thanks for your reply!
So on a phone with a dual camera, what would be the purpose of the dual lens?? If one is rgb and the other monocrome, don't they both work together to provide depth information and zoom? Or do all colour pics use just the one rgb lens and the other is exclusively for b&w pics?? Seems a little pointless to me...
You are totally right about the sw upscale to 20mp as any other camera app only detects a maximum resolution of 12 mp, but it seems strange to me that even on 12mp colour pictutes, the phone wouldn't use both lens (depth and zoom) because the inferior P20 Lite precisely doess that on all the reviews I read about it (I've always thought that was the point of all dual-lens cameras).
Cheers!
The B&W sensor should provide depth information. You can try different camera modes and cover the B&W sensor. The phone says "Please do not cover the lenses." in some camera modes. But if you don't put finger too close, nothing happens. I can't tell it does anything at all to the image quality which seems strange. Did they made some mistake in latest build? It only does have some effect on aperture mode when you can see heat haze effect on display. It sucks we don't have more options like jpg quality or sliders for post-process filters.

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?

Ultra-wide angle camera color science is off?

Apart from the frustrating fact that you can't record video and that the ultra-wide lens isn't very wide, the colors and seem to be extremely off in the comparisons I've seen to the point that I don't know if it's solvable through a software update. Maybe fixing the distortion and the super low saturation through software will somewhat save it, I don't know. Heck, even Mi 9 has a clearly superior ultra-wide WITH recording. What do you think? Does anyone that has the phone have a different experience? I want to buy this phone, but at this point in my country it's about the same price as a S10+ (Exynos) and I'm struggling to make a decision.
I wish GCam mods come early to save this mess.

I cannot answer specifically to the 7 Pro, but I can tell you that the colour science is off on my now-sold Galaxy S10 Plus Exynos version. Switching between the main lens and the wide angle lens in the same exact lighting and spot yields different colour reproduction. It might be down to the actual lens used in junction with the software, but I can safety say that this problem isn't exclusive to the 7 Pro if anything.
Also, don't buy the Exynos version of the S10. It has garbage battery life, and has different camera lenses to the SD version that have shown to be inferior to the SD version.
There is a setting in the camera called "Ultra Wide Lens Correction." I wonder if testers are switching this setting to see if this is the issue. I just got mine, but it's night time right now so I will need some time to test (but I only have the LG G7 ThinQ to compare to.)

Yes, but at least every other wide angle camera in the market gives decent results. 7 Pro's results are very undersaturated, very soft and sometimes seem like out of focus.
I know about the S10+. If it was a Snapdragon version I would have already bought it.

Great! Post some samples when you can. I'm not that worried about the lens correction, I don't mind the distortion. My problem is mainly the saturation and softness of detail. If you can, post original results + "corrected" versions using Snapseed/Photoshop to check if some post-processing saves the day at least. Thank you in advance!

Beauty of OnePlus and this wonderful community is the fact that there'll be GCam for it very soon, and we'll undoubtedly be able to take amazing shots through GCam using the wide angle lens.

It really depends. It might not be fixable with gcam.
The main camera uses a pretty good sensor. But it is a different sensor for the wide angle lens. So the quality of the wide angle shots will heavily depend on the quality of the sensor they use for their wide angle lens. It might be a weak sensor, we don't know right now. Huawei uses 4 Sony sensors for example, their wide angle pictures are pretty good. And yes, the best hardware is useless without a good software. But the best software also can't fix a bad sensor.
Not saying that it is a bad sensor, it's just that we don't know by now. We might have to wait for a teardown and some talented devs to see what is inside and if it is fixable.
I can only link you the specs from dxomark:
Primary: 48Mp Sony IMX586 sensor (12Mp output size), 26mm-equivalent lens with f/1.6 aperture and OIS
Ultra-wide: 16Mp sensor, 17mm-equivalent lens with f/2.2 aperture
Telephoto: 8Mp sensor, 78mm-equivalent lens with f/2.4 aperture and OIS

camera lenses

Hey, anyone found any external lenses for the p20 pro camera, I had a nifty little set for my p20 wondering what other people have been using
If you mean for the P30 - as this is the P30 Pro xda page - then it's unlikely.
I have tried using kit lenses with mine and it's a royal PITA because it keeps changing between the lenses automatically. As such you can't predict what it'll try and use and how the resulting image will be affected. Was far too much faff, especially when the 10x hybrid zoom works perfectly fine for my needs.
Yeah p30 pro lol my bad writing.
All these multiple camera setups seem to have killed the lenses off
I wouldn't say that's a bad thing to be honest. From my experience they gave a very narrow field of view, major vignetting and required you to crop the image after taking. This then resulted - in recent experience - in an image that is of lower quality had I just used the digital zoom of the device itself.
It's a blase statement, but if you want to be taking pictures with mega zoom then look to get an entry level DSLR - it's a huge step up over a smartphone camera, even in today's world, and you can get yourself a nice cheap telephoto lens that'll take pictures of things at the end of the garden like you're stood next to them.
Buy a cheap £8 lens for your high-end camera and you'll likely have a bad time. You'll also encounter the issues of laser autofocus not being able to function as the lens will block it resulting in crappy focus as well.

Camera OIS/sharpness?

Hi folks,
I am presently playing around with my P40 Pro, especially the camera as this is of special interest for me.
I am comparing with a Oneplus 8 Pro.
What I noticed is that the P40 Pro camera is giving a lot more blurred images at medium to lower lighting, in fact it's surprisingly diffcult for me to get a sharp indoor shot.
This is on .122 Firmware and I am bit at a loss on how to tackle this, in fact it's a bit disappointing for such a hyped camera.
Isn't the P40 pro camera supposed to have OIS?
And this is with very comparable aperture and shutter speed between OP8P and P40P...
Am I the only one? Any suggestions?
Thanks,
Axel
Are you using Google services?

Yes... Why?... Is there a known influence?
What do you exactly mean by blurred photos. Motion blur or out of focus blur? Motion blur is caused by slower shutter speed. Focus blur by focus failure. There is also blur(bokeh) caused by much bigger camera sensor used in P40 PRO. So depending what your subject is you may experience different results. Longer shutter speed and lower ISO is preferred for best image quality as long as you have static scene. But in scene with moving object, object in motion can be blurred. Personally I am on .121 and I rarely get blured photo due to any phenomena described above.

To me it seems like motion blur from camera shake... But images at around 1/30s with OIS should normally be fine - at least they are on the other handsets I tried...
This is why I am asking, maybe OIS is not working... Anybody got an idea to test this with some tool?
Have you contacted Huawei customer support? Could be faulty, it also may be worth checking out the huawei community page to see if that is the case

Yeah, firlando code method creates on my night shots some effect lines and on a1234567 method i have good night shots but blurry fotos on daylight... Today i will try to use my phone without Googleplay services...
This installing method on Google services witch you need to go on apps and delete playstore etc i think is the keys for the problem... We need a clean installation without deletations..

Wrong
Observation about the lines in the foto. Lines are reflections from lights. I realised it today. Im testing camera without Google services. Tomorrow i will test on daylight.. I think 121 update is bad update.. is there any way to roal back to 112?
Here its a foto without Google services... Still no sharp almost blur... I think is Just the 121 update is worst than out of the box 112 version
We just w8 the 127 update

I am also disappointed with this update (121) pics quality is average but video quality is lower than on p20 pro.
Zoom doesn't seem to work properly either - it's digital up to 8,5 -10 x then periscope kicks in.

Erm ... I don't see anything wrong with that picture.
You focused on the closed petal at the left side, it's perfectly sharp, rest blurred as it should be. Not the prettiest bokeh, but okay.
Do I overlook something?

Again, I don't see what's wrong with that picture. Maybe you could point out the problem a bit more in detail?
It would also be quite helpful for sorting out culprits if you (and anyone else) accompany your pictures with some EXIF data, like shooting mode, AI on/off, ISO, exposure, aperture and zoom factor. Unfortunately, XDA seems to remove that data from posted pictures.

That's indeed the case with firmware .121. And it's far worse in the "Pro" mode, rendering "Pro" mode almost useless.
Let's hope the next updates home in on that fault.
Look the sharpness on 112 version

EXIF data? Answers to me previous questions?
These are important information, e. g. telling me about the aperture of the lens used, making a difference regarding depth of field, possibly explaining why you *perceive* a picture as not okay.
Besides that:
Similar quality, similar sharpness - if not identical.
This time, there was more distance to the subject, widening the depth of field, the "sharpness range."
Let's assume the picture was taken with the main 50 MP camera, having an aperture of f/1.9 - a big difference to the aperture of the telephoto lens with f/3.4.
The smaller the f-number, the larger the physical lens opening. And the larger the physical lens opening, the shallower, smaller the depth of field.
Meaning: With a shallow depth of field, a few millimeters more or less distance to the subject can make the difference between razorsharp and blurry. Result: Only objects exactly within the depth of field are rendered sharp.
With a wide depth of field and a larger distance, like with the telephoto lens, it's less crucial, every part of the flower will be sharp.
I would show you example pictures if I was allowed to use external links - but my post count is still too low.
Just try taking pictures of the same flower with different lenses, one with the 50 MP main camera, one with the telephoto lens. With the latter, increase the distance till the flower roughly occupies the same space in the viewfinder as with the main camera.
Important: Use a zoom factor of 10, not 5 - this makes sure your really switch to the telephoto lens. At present, there's a software bug causing the camera to often use horrible digital zoom for 5 x instead of the real telephoto lens (seems to be connected with the metered subject's distance). You can check this by covering the rectangular telephoto lens with a finger. If the picture vanishes, the lens is doing it's job.
You'll find out that the photo taken with the main camera has sharp and blurry areas, while the photo taken with the telephoto lens is rendered sharp everywhere.
That's the results of aperture and distance.
And that's why I don't see anything wrong with your first flower picture: Wide open aperture, small distance = tiny depth of field = tiny area of sharpness.
The way it should be because we all like that bokeh effect (blurry background, making the subject stand out) more than typical "flat" smartphone pictures.
But this benefit is paid with a drawback, the small depth of field, rendering everything outside that "sweet spot" blurry.
Perfectly normal, nothing to write home about.
Oh wait, I'll dare to post a link anyway - hope the moderators won't kill me for that impertinence.
Just took two quick photos right outside my house, clearly showing the effects I explained above.
http://waagerecht.com/kram/Flower_comparison.jpg
Picture is quite large, so be warned.
Telephoto: ISO 50, f/3.4, 1/196 s. Main lens: ISO 50, f/1.9, 1/846 s. Both shot in Photo auto mode, no AI.
About that numbers: ISO 50 tells me there should be no grain in the picture; the higher the ISO, the more grain in the picture.
f/3.4 tells me there's a wide depth of field, so there should be no greater blur. Also tells me the telephoto lens was used. f/1.9 tells me to expect blur everywhere outside the "sweet spot", main lens used.
1/196 and 1/846 tell me about very short exposure, so in-motion unsharpness (camera shake, moving subject) is very unlikely.
And because the telephoto lens has a smaller aperture of f/3.4 (and lenses with a higher curvature), less light reaches the sensor, thus exposure time is greatly increased, 1/196 s versus 1/846 s.
See why I asked for that data?
You'll see that the telephoto shot is all sharp (until you zoom in; lower sensor resolution plus digital zoom, today's modern pestilence), you can even see the structure of the green leaves, while the main camera shot has everything blurred except the flower's pistils.
That's just the way cameras work.
So enjoy your fine camera, it does a great work and does it right.

Jeasus Christ i never used 50 mp sesnor i use the normal sensor for the red flower and also same sensor with pink flower... im changing so many phones every year and i can clearly understand what a foto needs! P40 pro with 122 version is less detailed on normal shots than with 112 , i need t use night mode on day light fotos to get some sharpness..
Also the foto you have posted there is no detailed at all i can taje same photo with my xiaomi mia 3 Stock camera apk... and i can get also much better shots withy GCAM on mia 3!
