Could someone please confirm that if 90mm lens on current projector
gives me the correct projected image size, then 90mm lens on another
projector will give the same projected image size, even though aperture
is different?
Simon, the aperture should have no affect on the image size. Assuming the
distance from the projector to the screen or surface project on is the same,
the image size should be the same. That is all accurate unless I've lost my
mind and there are those who might say that is the case. Bill Barber
