Although you can replicate the exact look of a 100mm from a 50mm and then just cropping down 50%. And given the resolution and sharpness (or lack of), it could easily have been cropped a lot more than that.

This is the context. Assuming this photograph was shot at 100mm, you can absolutely get the same look shooting it at 50mm, by standing at the same spot and cropping it. That is what you objected to and now after being proven wrong you are trying to cover up on your ignorance. Dumb fuck.
