The lens of the camera is not a flat piece of glass, it is curved. The curve of the lens distorts the image a little, making certain things seem larger than they actually are.

Different methods of recording and playing back use square pixels or rectangular pixels. When going from one to the other, the video gets "squished" to fit the new format. With decent editing software, it isn't hard to correct this problem, but often it is ignored. The lens does distort the image slightly, but if the lens is made correctly, it distorts the image the same way in all dimensions, so the net effect is barely noticeable.

when filming indoors, you need to use wide angle lens to get all the subject in the frame. Using a wide lens does distort the perspective. i fouy can move far away and film with a zoom, you won't have that problem.
For portraits, pros use a lens with a focal distance around 80 to 105 mm (for a 35 mm camera) which gives pleasant results.

This is due to the distortion caused by wide angle lenses (aka short focal lengths).

i agree with all of you!
but why is it like that? can't they correct it and have a flat one instead of curved?
one of the reasons is that lens is made of glass that it has to be produced with a little curve to make it stronger (like how they build dams!).
And if you ask me, 4lbs is not that much!
