Someone on a Canon group on Facebook stated that on a crop sensor such as an 80D you multiplied not only the Focal Length by 1.6, but also multiplied the Aperture. He stated that this was because you're putting it a full frame lens on a crop sensor, you times the focal length and aperture by 1.6. A 50mm f1.8 on a crop sensor is actually equivalent to an 80mm f2.8.
I have never heard of this before. Is it true?
