77, 01 Oct 2022Ugly nasty iPhone notch ruined itThank you for your sentiment. Sorry if the product doesn't meet your expectations. The Mate 50 Pro's notch houses a 13 MP ultrawide and biometrics sensor. Instead of adding two separate punch holes or a pill-shaped one, a small notch was added.
If you need further help on choosing the right device to purchase, I can't do that.

Anonymous, 01 Oct 2022I won't be making further comments on this topic as an... moreOf course, these are all fixed lenses. And phone manufacturers can portray the telephoto as "zoom" by dividing its focal length to a "separate" and widest camera module. It's a made up thing.
I suggest that you visit a camera store, ask for a zoom lens, and look at the zoom factor. You'll get numbers like ~3x, ~4x, etc.
Presenting a single FIXED lens with an optical zoom factor is simply a pathetic attempt to mislead consumers.

AnonD-1026644, 01 Oct 2022I think both of you are referring to different calculations... more"On a smartphone, as someone mentioned, the focal length of the telephoto camera is divided to the focal length of the main to get the optical zoom factor. Is it the standard way of doing it? For decades of photography, I think someone just made that up."
Actually it's not made up, research confirms it, I request you to divide the telephoto lens's of any smartphone by it's main sensor's focal length, and you'll get the advertised zoom factor. e.g, s22 ultra's 230mm telephoto/23mm main=10x zoom as advertised. it works for any phones, try it out, it's quite consistent other than some rounding down. Also you'll find that ultrawide sensor has almost half the focal length of main one (13mm for s22u).
unlike in DSLR/mirrorless, on phones you can't take off and put on lenses on a sensor. so you have multiple sensors each with different focal lengths for different purpose (and main sensor is used as the reference 1x, usually 23mm-26mm of equivalent focal length).
And if fact, in that case, if your fisheye lens is 7mm and telephoto is 600mm, then indeed it's ~85x zoom but, only as a relation between that fisheye lens and telephoto. Would you really use 7mm fisheye as a reference? Or rather the standard one which varies between 35mm - 85mm?
So, lets say your standard lens has 60mm focal length and telephoto 600mm. then it's 10x zoom.

Bionic Chip, 01 Oct 2022Very funny. This is how a zoom lens specs should be present... moreHopefully one day our phones' main camera will have variable focal lengths, so we won't need separate telephoto/ultrawide modules. Galaxy K and s4 zoom design poses many problems for a day-to-day smartphones which is why it's not been carried on.
But now Xperia 1-IV has a telephoto camera where the lens moves back and forth in a periscope assembly to change focal length and you can do continuous zoom.
I think it's actually doable now if they don't mind increasing the phone's thickness by some, We should be fully for it. Who wouldn't like to get same quality in their ultrawide and telephoto as main sensor in expense of some added thickness?

AnonD-1026644, 01 Oct 2022I think both of you are referring to different calculations... moreYou should be referring to a 12mm ultrawide lens as base focal length (not 7mm).
On your bag was another lens unit: a 600mm telephoto with a 2x teleconverter.
600mm * 2x = 1200mm
1200mm/12mm = 100x
That gives you a 100x optical zoom as a whole person carrying a camera and a bag full of lenses. Genius.

Zoom lens:
16 MP, 1/2.33", 24-240mm, 10x optical zoom, AF, OIS
If it's a fixed 90mm lens then:
f/3.5, 90mm, PDAF, OIS, 3̶.̶5̶x̶ ̶o̶p̶t̶i̶c̶a̶l̶ ̶z̶o̶o̶m̶
The specs only refers to one lens, 1 camera module, straightforward.

I don't really understand this lens now-a-days, but I will wait for the phone to come out so I can try it out myself, bc for me the zoom from p40 pro or the mate 40 pro are much better than this one or p50 pro.

notafanboy, 01 Oct 2022Man you're so smart, everyone wants to be like you.Thank you. I guess you also like to divide the telephoto's focal length to the main cam's. That's the smartest thing in the world of photography. Separate camera modules, the same optical zoom. Wow.
If that's the case, the following statements are all du.mb:
SLR Lounge:
"For example, a 50-100mm zoom lens would be 2x zoom, and a 50-150mm zoom would be a 3x zoom."
Sigma:
"To determine the overall zoom ratio of the lens, simply divide the longest focal length by the shortest."

notafanboy, 01 Oct 2022Man you're so smart, everyone wants to be like you.He's talking about dedicated zoom lenses for DSLRs. The zoom factor is indeed, the quotient of the max zoom and the base focal length.
The other guy is talking about smartphone with multiple cameras which is a different story, unfortunately.

A zoom lens basically zooms in or out. It means there is a starting focal length and the maximum focal length. Divided the max focal length to the shorter one and you get the zoom factor. BUT this only refers and applies to ONE lens; not two or more lenses.
On a smartphone, as someone mentioned, the focal length of the telephoto camera is divided to the focal length of the main to get the optical zoom factor. Is it the standard way of doing it? For decades of photography, I think someone just made that up.
It's like having a 7mm fisheye lens on your bag and on the other hand, you also get a 600mm telephoto with a 2x teleconverter. Does it mean you have 1200/12 = 100x zoom?
Ridic.ulous.

Manufacturers can always find a way to exaggerate the numbers in order to sell more. This device for example comes with the so-called "Kunlun Glass," but it turns out that only the orange variant has it.
I just like to add the footnotes from Mate 50 Pro's product page:
"1. Only the Orange version features Kunlun Glass."
"2. ...device is protected against harmful ingress of static water at up to 2 metres for the Silver and Black versions, and up to 6 metres for the Orange version, for up to 30 minutes."
The downsides or negative aspects of the product are hidden in the footnotes; the "amazing" features are emphasized or exaggerated heavily in order to hijack your critical thinking. Just like the false 3.5x zoom of the Mate 50 Pro's telephoto.

Isn't it a marketing tactic to increase the advertised optical zoom? It's all trickery and marketing.
Therefore, in a triple-camera setup starting from ultrawide to telephoto, you just have to use a wide lens with the lowest focal length and add a separate telephoto module with a high focal length. Divide the focal length of the telephoto to the wide and there you have a seemingly "large" optical zoom.
Ex. Wide: 12mm, Tele: 200mm
Optical zoom for advertising: ~16x (200/12) 🤣
Looking at the Huawei's Mate 50 Pro's product page, the footnotes confirmed it all. It's more like a sc.am than actual specs.
None of these are "zoom" lenses. They are all, indeed, fixed or prime lenses.
Buying a camera lens for your DSLR or mirrorless body is a different story. You would ask for the zoom factor and zoom range. The lens specs are engraved on the lens. That itself, is the proper way of presenting the correct zoom range and focal lengths in all honesty.

Anonymous, 01 Oct 2022I won't be making further comments on this topic as an... moreI get it. I found it on DXOMARK's testing. Under Zoom tests, all focal lengths are converted to their approximate FF (35mm) equivalent. Reading the iPhone 14 Pro's review, the zoom range is 77-200+mm, which confirms the 3x optical zoom and the zoom range.
I compared the specs from GSMArena, multiplied it with the published zoom factor, and it's consistent with DXOMARK.
The published focal length (35mm equivalent) of the telephoto specs here refers to the shortest focal length of that lens. You get the maximum focal length by multiplying that number with the published zoom factor. Hence, we get an approximate 315mm at the longest focal length.
Taking "that" into account, we get 90-300+mm zoom range for the periscope telephoto lens.
Huawei Mate 50 can, in fact, zoom in 3.5x from 90mm with its telephoto lens only.

Is it the actual focal length, or the full frame equivalent, or is it even the shortest or longest focal length? I wonder why Huawei didn't provide specific detail on this telephoto feature.

If you see a lens with a zoom factor, it's a "zoom lens." These are photography basics and can be applied to any lens, big or small.
Zoom lenses are called as such because their focal lengths "zooms" optically. It means the focal lengths can extend from the widest to longest based on its design.
Mate 50 Pro can achieve a 3.5x zoom because it has a periscope telephoto zoom lens. That's it.

Anonymous, 01 Oct 2022I won't be making further comments on this topic as an... moreI own the lenses I used in my examples. Don't try to bully you but I know what I am talking about zoom factors, otherwise I won't buy these lenses if in the first place, I can't determine how long the zooms are going to be.
Either it's a camera lens or phone lens, the zoom factors are the same. You simply convert the focal lengths based on crop factor.
But you know what, I find it interesting to know the MAXIMUM focal length that the Mate 50 Pro can achieve. I might even contact Huawei support to figure this out as I am curious about this periscope technology and how the lenses work.
Not to mention the variable aperture.
Anyway, if this phone becomes available in my country, I'll buy it.
But based on experience, a 90mm is not enough to zoom in enough to take moon shots.
"If you are shooting the moon alone, you can get pretty good results with a 200mm or 300mm lens" — BHPhotoVideo
Therefore, my 315mm estimate (90mm * 3.5x) as max focal length makes sense here.
I'll contact Huawei to make sure.
