Hi,
I am looking for a scope lens which can be put as close to the projector lens as possible. Does anyone have an idea which one I could use?

There is too little distance to my screen in the room (approx. 4 metres) and if I take my Kowa-scope lens in front of the projector I get a too small image at the screen; the light "gets lost" on the scope lens itself if I make it big.

Is there a scope lens, that would match with the seize of my Beaulieu-lens and is not too long to create a bigger image?

Thanks!

You're lucky to own a projector like this.

I think this is the fate when using any scope lens you will loose some brightness.

Otherwise you need to find a short throw lens for your projector and using the same scope lens.

Dominique wasn't being critical. I would hazard a guess, the KOWA
is a great lens for 8/16mm, and should show your films no probs
