Generally speaking, closer will be brighter. My throw is 14' lens to screen too.I apologize if this has been discussed and or asked already...
Is there any lost of light output or reduction in brightness with the NX7 if it is mounted further back from the screen, or is better to keep it as close to the screen (within required distance) to keep a brighter image?
Looking at either the C-DCR lens which would require me to mount at a minimum distance of 16' or a DCR lens @ 14'
sorry for the emoji, not sure how it got there or how to get rid of it
