Blender Camera Settings Millimeters/Field of View conversion I have a question concerning the camera setting. You can choose between tweaking the field of view or the mm settings.

I use a 50 mm objective on my canon 6d. The field of view for this lense is at a fixed 46° angle.

So I set up the camera in my scene and set it to 50 mm. when i switsh to field of view it is set to 39,4° which ist more narrow than the angle of my real world objective.

Which settings should i use to fit my real world camera objective?

Any suggestions?
It's because the sensor's size plays a role either. Wikipedia says:


  So a standard 50 mm lens for 35 mm photography acts like a 50 mm standard "film" lens on a professional digital SLR, but would act closer to an 80 mm lens (1.6 x 50mm) on many mid-market DSLRs, and the 40 degree angle of view of a standard 50 mm lens on a film camera is equivalent to a 28–35 mm lens on many digital SLRs.


Hence, you need to increase the sensor's size to 42.447 
I believe there's a formula for this.
