How can a camera be both 12MP and 1080p, when 1920x1080 is just 2,073,600?
1080p refers to video: 1920×1080 progressive scan. The phone is capable of 12 Mpixel still images but only 1080p video. (This is fairly typical; it takes a lot more processing power to take video at a ...

What is this notation for Diagonal Angle of View units in this lens specification?
This is the standard minute and second of arc notation for fractions of a degree; one minute (′) is 1/60th of a degree and one second (″) is 1/60th of a minute.
(I am slightly suspicious that the ...

What is this notation for Diagonal Angle of View units in this lens specification?
In trigonometry, degrees are subdivided into 60 minutes (indicated with a single quote or apostrophe). Each minute is further subdivided into 60 seconds (indicated with a double quote). So 74 degrees ...

There is no shutter in the 24-105; almost every camera system smaller ...

How can a camera be both 12MP and 1080p, when 1920x1080 is just 2,073,600?
The difference is that the video image is processed from still frames. The data transfer rate for full sensor resolution (i.e. 12 Mp) would be too high for normal use and there's no standard for such ...
