Ultra-Wide Camera - definition
Today’s smartphones have different camera sensors instead of one single lens which are wide, ultra-wide, macro, depth, and a few others. The ultra-wide sensor usually takes the photo in such a frame in which the view becomes wider and a lot more objects can be fit in one frame compared to the normal mode. Technically if the aspect ratio of a picture becomes more than 2.0:1 then it becomes a family member of the ultra-wide picture. Also, a wide-angle camera sensor can take the view of 60 to 84 degrees but ultra-wide it becomes 94 to 118 degrees. In addition to the fact, wide-angle sensors use 24mm to 38mm equivalent focal length whereas ultra-wide sensor supports 13mm to 20mm equivalent focal length.
