Hey Guys,
would this lens work to get the projector further from the screen ?

Lens features:
Outer Diameter: ~135mm
Back Focal Length: 380mm
Effective Focal Length: 450mm

Tnx !

remember you have to have a fresnel that matches your lense. how to match it im not sure but brainchild could tell you .from what i have read so far to match one to a lense triplet that size may be a special order and costl
