Focal length does affect perspective .
No it doesn't. I don't know f the cheesy emoticon means you are being ironic or something, but focal length does not affect perspective.
Yes it does .Focal length has no impact on perspective. Perspective is a function of distance.
Well, I'm talking about the picture. You can't shoot the same thing using different FLs from the same distance without changing your camera format.
Same distance + same angle (whatever FL and sensor) = same perpective.
But, same framing + different FL = different distance and perspective.
The FL doesn't matter only if you are photographing the perspective from a fixed position and you don't care about framing (for whatever reason).
FOV and framing has nothing to do with perspective, that is where you are going wrong.
If we change this "Same distance + same angle (whatever FL and sensor) = same perpective."
to this "Same distance
+ same angle (whatever FL and sensor)= same perpective."
Then you will be on the right track.
FOV and framing has everything to do with distance, which affects perspective.
