Galaxy SArticle from Notebook check
Please read the article from the link below.
While the Samsung Galaxy S20 Ultra may be the best choice for the discerning mobile photographer and videographer, the $1399 price tag may lead most of use to consider the more sensibly priced Galaxy S20 and Galaxy S20+, all you'd miss is a higher megapixel main camera, more zoom-range, a slightly larger display and a bigger battery, right? Wrong!
When it comes to the cameras, the virtually hidden specsheet of the Galaxy S20-trio reveals a pretty massive difference between the Galaxy S20 Ultra and its slightly smaller siblings. However Samsung's clever marketing trïcks try to cover it all up. Neither the Galaxy S20 nor the Galaxy S20+ have any kind of real zoom camera, the so-called "Telephoto Camera" only offers a ridiculously low 1.06 optical zoom factor, which is essentially no magnification at all. The touted "3x Hybrid Optic Zoom" is a mere crop into the (presumably) 64 megapixel wide-angle image, followed by regular, lossy, 10x digital zoom.
As you can see from the official Samsung spec sheet above, both "Telephoto"-lenses in the Galaxy S20 and Galaxy S20+ have a 76-degree field of view (FOV, highlighted in red) as opposed to the 79-degree wide-angle main lens. Basically, both these lenses can be considered wide-angle, the "Telephoto" one has the above mentioned 1.06 times narrower field of view. Samsung does not reveal the focal length of these lenses but they should be around 26 mm equivalent (wide-angle) and 28 mm (telephoto) - very similar optical characteristics.
Instead of offering any kind of real optical zoom, Samsung instead uses the 64-megapixel image or video (presumably 64 MP, since there might be pixel-binning in place: Update: No pixel-binning involved as we learned) and crops into it to simulate getting closer to an object. Samsung calls it "3x Hybrid Optic Zoom" but as we established, the real optical part is just 1.06x - basically nothing. Still, because of this tiny optical magnification, Samsung is technically not wrong, calling it "hybrid", mostly it is **bleep** zoom though - a mere crop, albeit lossless up to 3x, followed by 10x digital zoom, which Samsung calls "Space Zoom" but will lead to image deterioration as Samsung correctly warns in the fine print.
Other manufacturers have been accused of using similar tricks in the past to tout a higher zoom factor. The latest, OnePlus in its OnePlus 7 Pro, at least offered a real 2.2x optical lens and added a bit of crop to achieve the promoted 3x zoom. Compare that to Samsung's 1.06x optical lens with up to 3x crop: In our opinion, it is quite deceiving to call this combination "Hybrid optic zoom" and the 64 MP camera a "Telephoto-Camera".
So why did Samsung choose to basically include a second 64 MP wide-angle lens instead of a real telephoto camera? Well, while we do not know for sure, we do have our suspicions. Thanks to the Snapdragon 865, the Galaxy S20-series is capable of 8K video recording. This, however, requires a 33-megapixel sensor or higher; anything below simply does not cut it. That is why the 12-megapixel main sensor is not used if you record 8K video with the new Galaxy phones. Instead, the Galaxy S20 will activate the 64-megapixel sensor automatically thus it needs to have a similar field of view as the main camera.
Maybe Samsung considers this 64-megapixel sensor to be of inferior quality to the main 12-megapixel sensor and therefore decided to keep both? We don't know. This does result in a bit of a mess, though, because the main sensor is useless for 8K video and the 64-megapixel wide-angle camera doubles as a **bleep** telephoto zoom lens. We know that most people who just want to "zoom in onto an object" will not be able to spot a difference between optical magnification and cropping; however, there are creative differences for instance regarding depth of field or background-to-foreground separation. Neglecting this and calling a wide-angle lens "Telephoto Camera" with "Hybrid optic zoom" could probably be criticized as deceitful marketing practice.
There is a solution for Samsung fans, if you are willing and capable to spend $1399 and up. The Galaxy S20 Ultra does indeed feature real optical zoom. Here the Telephoto-Camera starts off based on a 4x-5x optical periscope lens with a very narrow 24-degree field of view - probably comparable to a 35 mm lens with 100 mm focal length. It then adds up to 5x crop into the 48-megapixel image which results in up to 10x hybrid optic zoom. On the Galaxy S20 Ultra, this term can be considered truthful. Also, the 108-megapixel main camera is capable of 8K video so there is no need for a second wide-angle camera.

Galaxy Sthis reveals that Samsung in only marketing phone Samsung does not wants to give features only wants to focus on camera and display of bezels state Samsung should reconsider about the tech which was important in the field of flagship if flagship matches the mid-range segment then the flagship is of now use that becomes mid-range phone with some extra little features like wireless charging and ip68 rating, moreover Samsung hasn't provided the world-class security system like iris scanner or 3d face scanner they just stuck on the old fingerprint scanner I don't know what Samsung was planning but also Samsung removed the heart rate sensor in favor of expensive active watch series I know its marketing but it too much expensive for us to have it Samsung should give heart rate sensor, world-class security system in the flagship segment like 3d face scanner or iris scanner flagship deserves it moreover if Samsung has made a camera for the smartphone they should include dual autofocus and dual pixel and variable aperture system
