Hi.
Is there a way to obtain or calculate the Field Of View (horizontal and vertical degrees) of the transferred pictures ?
I have a D7000 and a D3200, and it seems the pictures hasn't all the needed EXIF information or device information (inside the ICameraDevice) to calculate it.
It would be enough to have the focal lengh (in mm) and the sensor size (in mm), but AFAIK, only the focal length is available into the EXIF descriptor.
Without the sensors size I cannot calculate the FOV.
Is there this information somewhere ?
Thanks for your help.
BTW, these are sensors sizes (x,y,p) for some cameras, if you need them:

How to calculate FOV
Hello,with NEF-files from Nikon D800 you can directly read horizontal FOV from EXIF data.Following an example of data read with EXIFTOOL. You find the interesting values in the COMPOSITE section. Tag name is: "Field Of View". Also interesting for you may be value of tag name "Scale Factor To 35 mm Equivalent" which - in my understanding - gives you the crop factor.C:\Program Files (x86)\ExifTool>exiftool -a -u -g1 C:\Users\xxx\Pictures\_DSC2116.NEF---- ExifTool ----ExifTool Version Number : 9.31---- System ----File Name : _DSC2116.NEF...
