Anonymous, 14 Jan 2021Do you even understand that f stop only indicates an aperture of a lens relative to the sensor... moreAmen to that, F stop only shows the ratio between the focal length and the diameter of the pupil. On top of that, many smartphone manufacturers seem to use "increase in sensor light sensitivity" and "increase in the amount of gathered light" interchangeably (e.g. Apple's product description page for iPhone 12 Pro Max).

Anonymous, 14 Jan 2021Do you even understand that f stop only indicates an aperture of a lens relative to the sensor... moreWrong.
Aperture, is simply the diameter of the diaphragm. Your aperture is written as focal length divided by the ratio of focal length to aperture. So if you have a focal length of 50mm, and an aperture of f2, you can use these 2 pieces of information to work out the exact aperture in millimeters. 50/2 =25mm. Because of the severe crop factor of phones, phones (even zoomed in) have a focal length of around 4-10mm depending on the sensor size, the diameter of a wide angle lens will let in more light at the same diameter as a telephoto lens. So, a 10mm f4 lens needs a 2.5mm aperture, whereas a wider 4mm lens will need only a 1mm diameter for the same f4 aperture. I don't know the exact focal lengths and crop factors on phones, but I DO know that sensor size is irrelivant to your aperture (in focal length ratio aka f/stop) an f4 lens will always leave in the same amount of light (assuming identical perfect conditions) as an f4 lens. You will never be able to make an f4, and an f5.6 lens match in light transmission (again, in the same perfect conditions) assuming you don't use nd filters or light blocking coatings on the glass. I used different numbers to you here, but the same maths applies.

i know im right, everyone knows it, you do too. E2100 will be the new thermal throttle king in 2021.
sustained performance will be the worst on any exynos chip, ever.

Assuming both lenses capture the same horizontal field of view, a f4.9 lens sitting in front of 1/3.2" image sensor has a larger opening than a f4.4 lens in front of 1/4", therefore is capable of letting in more light. Samsung engineers aren't stupid, bruh.

Anonymous, 13 Jan 2021the note 20 ultra is 5 months old, not sure where you think it was released a month ago so you... moreCalm down buddy. I never said anything about the Note 10+ as I have never had any desire for it. Simply stating what I read about the positive reviews, not that I've read everything ever published about every thing ever invented.
Yeah, I embellished the newness of the phone, but it is still within the 1 year of warranty so why not utilize it instead of complain?
And for you being this amazing photographer, that's awesome and I wish you the best of luck and what not, but don't tell me what my eye's perceive as better pictures.

Gsmarena is full of tech engineers bashing samsung😂😂😂😂🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡🤡I used to defend Samsung when engineers built their phones. These days, it looks like marketing and finance team tells the engineer what to do instead.
Artificially limiting technological developments so there is something new to be introduced the next 3 years. For these big companies, they have at least a 3 year road map of what they are going to do or sell. 80% of phone features are planned 2 to 3 years in advance. It is very obvious that Samsung now operate on a "do not exceed $X in costs for each phone" model rather than "innovate the XXXX out of the phone at all costs".

Nick Tagataka, 14 Jan 2021Nope, P40 Pro+ captures LESS light in this case because the sensor was substantially smaller o... moreDo you know anything about photography? Did you get your knowledge from the vegetable counter in Walmart?
Larger sensor does not capture more light in a camera system. The amount of light hitting the sensor is limited purely by the aperture. A larger sensor cannot capture what does not exist.
What a large sensor can provide for, is more accurate light information without distortion (commonly seen as noise in photos). When there is less perceivable noise, the software can boost sensor sensitivity to the light.
Small apertures in a phone camera system will have diffraction limitation issues. The entire science is explained online. Hence, the smaller the aperture, the worse the photo quality. There is no way around it. Its the physics of light.
Boosting sensitivity while reducing aperture is what a money grubbing company would do, since it significantly reduces the costs of building larger aperture systems.
Whoever designing the first Huawei phone camera systems is definitely a photographer with extremely in depth scientific knowledge. They actually focused on increasing sensor size while keeping aperture big.

TheLastOracle, 13 Jan 2021You're incorrect. It is actually a Zoom lens, and that's why the Entire Industry use... moreYou managed to make yourself sound like a fool with your first 10 words.
The industry does not call it a "zoom". Marketing does.
The camera has a fixed telephoto lens. That's a fact.
But, software provides the interpolation to give the zoom impression.
S21 Ultra has a 240mm equivalent telephoto but a 11mm wide angle. In theory, it can provide a 21x magnification. Why don't they call it so?
Hint: they still follow photography convention. Hence, I'm not sure where you read about phones having zoom, you may want to stop reading those rubbish sites.

P50 Pro+'s telephoto lens may turn out to be better than S21 Ultra image quality wise, but only under certain conditions:
-If it will use a more effective stabilisation system
-If it will have at least an equally sized sensor
-If Huawei can release any new flagship phone at all (due to US ban).

You're all can argue about the camera all you want, but please do not buy this phone. If the sales took a dive, the charger will make immediate return.

S21 Ultra will be the most powerful chip ever BUT only for about 20 minutes then it will thermal throttle like crazy and cut down performance to lower than the garbage E990 chip..
They also still use that garbage Mali GPU so the battery drain will still be absolutely huge!
DON'T BUY THE GARBAGE EXYNOS 2100 CHIP - GO FOR THE SNAPDRAGON AGAIN AND WAIT UNTIL 2022 FOR EXYNOS COMEBACK. IT WON'T HAPPEN IN 2021 DESPITE ALL THE LIES THE CRIMINALS OVER AT SAMSUNG IS SPEWING..

TheLastOracle, 13 Jan 2021You're incorrect. It is actually a Zoom lens, and that's why the Entire Industry use... moreCalling that lens a zoom lens is technically incorrect. It's used by the phone industry because it's the only term that the majority of the customer base would understand. In their eyes zoom = magnification, and a lot of people without technical knowledge call everything a zoom, and would ask questions like "how big of a zoom this prime telephoto lens has".
However, the fact that phone companies decided to take an easy path doesn't make it correct. When I heard about S21 telephoto lens being a 10x zoom, I was frustrated because for a second I thought that it's a variable FL lens which would be of significantly lower quality compared to fixed focals (lower resolution, lower uniformity, higher chromatic aberrations, higher distortion, potentially slower AF and worse aperture)
