The HF comes with four cameras, main 108MP with F/1.8 a periscope, second 10MP periscope telephoto imaging with  optical zoom aperture up to 10X and Zoom Digital up to 100X, third telephoto with 10MP rounding up to 3X, and fourth with 12MP resolution A 40-megapixel front camera with a F/2.2 aperture.

Main Camera

You can choose either 108-megapixel imaging or integrate pixels down to 12-megapixel efficient imaging by assembling 9 to 1 pixels. The latter choice is more effective at getting great images, not only because it gives clearer results with better light assimilation, but because the image size is much smaller and easier to share, which means it won’t take up much interior or cloud storage.

If you choose to take 108-megapixel still images, you will be able to enlarge the images taken in all the details further than the 12-megapixel images, but as we said it takes over a large area. So, 12-megapixel imaging in any scenario is almost more effective.

Regardless of the resolution you decide to shoot, the S21 Ultra camera captures very impressive images at an amazing level, and thanks to the large sensor you get great isolation images, DSLR digital cameras resemble.

Although there is no custom macro lens or macro imaging mode, the S21 Ultra camera actually does a great job of keeping the focal point close to the target. Even while filming is only an inch away. And get the exact details.

These types now include filtered videos, filtered images, speed effect clips, selfies, wide/cropped shots, and featured videos. They are all captured in about 10 seconds with one push.


The Galaxy S21 Ultra is Samsung’s first phone with dual closeup cameras, balancing two 10-megapixel sensors to offer 3x and 10x zoom. Both lenses are visually stabilized, and can be zoomed up to 100X.

Wide Camera

Cameroon Daylight offers wide camera images, thanks to an extremely wide 0.6x camera instead of the wider 0.5x camera that has become popular with Samsung’s latest flagship phones. The wide camera images are rich in clear details, and the HDR is great, with a great deal of color.

Front Camera

The front camera captures great images, containing full face details. You also have a great professional background insulation. The front camera supports the integration of four pixels into one pixel, for effective imaging in 10 megapixel resolution.

Selfies were generally bright and sharp, as is the option to expand the range of group photos. It automatically turns into a broader perspective when it detects many faces, and can recognize the face while wearing a mask.


Samsung outperformed itself in developing video shooting using smartphones. The phone is capable of capturing up to 8K video at 24 fps. Or 4K at up to 60/30fps, 1080px at 30/60/240fps, at 720pps with 960fps.
