It's amazing how much physics and math I have forgotten, so let me simply note that the focus of the camera isn't going to change the proportions of the objects. The focal length will. The perspective will change as your lens measurement changes (in (...) (23 years ago, 14-Aug-01, to lugnet.off-topic.geek)

"Mechas" is the incorrect plural form of mecha. Mecha is like the word "fish", it can be used both as a singular and as plural noun. Of course, if you're talking about non-Japanese-anime-inspired robots you can use the word mechs... ;-) (...) (23 years ago, 14-Aug-01, to lugnet.build.mecha, lugnet.off-topic.geek)
