For all of you wondering about compression
That is not compression, it is perspective!
+1 - it's due to the fact that the camera-to-subject distance was changed to maintain framing, and has nothing to do with the focal length of the lens.
PBD has posted visual examples of this before, as have I. I prefer mine, mainly because I was able to imbibe the subjects after the test.
Thanks... Never read that post because I became a member in 2013.
BTW... So you did enjoy the Chocolate Stout!
