We have just installed a new Sanyo PLV70 to provide video output in one of our lecture theatres. The device arrived with a standard lens already fitted but the technicians replaced this for a long throw lens.

Can anyone tell me what the model number of this supplied lens would be? I cannot find any markings on the l;ens body itself. Since it has never been used, we wondered if it had any value in the marketplace?

Many thanks.
