Longer the lens wider the image projection circle?

[Daniel Porto]

Hi,

Am i wrong or does a the longer a lens the wider the image projection circle? for instance on my komodo a 17-85mm barrels at 17 but 85 seems ok.... I am asking really because Im imaging a future digital camera that is like IMAX sized sensor with longer lenses to cover the obviously large image plane ?

thanks

Yes, longer lenses have larger projected images... but a longer lens designed specifically for a small format like Super-8 or 16mm still might not necessarily cover a large format like IMAX.
