Except for the vp4001 thread, there is very few picture bowing issues reported with projectors. My Canon digital camera produces a slightly bowed picture. A search on the net led me to believe that bowing is very common with cameras.


So do projectors need special design to not produced a bowed picture?

1. Do projectors use higher quality lens? or

2. Do projectors use special optical engine design to compensare for lens bowing?


I understand that comparing pj to camera is not apple to apple but if anyone has some information please share.

Bowing occurs as you reach the widest point in a lens whether camera or PJ. So as you reach the widest angle on either, you can expect to start seeing a bowing effect. PJs that also provide lens shift can produce bowing when you push the shift to the furthest extent available because the image is being projected through the outer edges of the lens assembly.
