>>2942945>>2942952It's confusing but I thing
>>2942945 is right. If you intend to frame exactly the same picture, a 28mm in APS-C will have the same perspective as 44mm in FF, but the position of the camera will be entirely different.
"In photography, there’s a common misconception that focal length determines the perspective of an image, but the only thing that really determines perspective is where you put the camera."
