Suggestions to fix vignetting on Letus 35?
 

Can somebody suggest a condensor or another method to fix the vignetting im getting with the Letus35?
I really like the Letus35 but I'd like to be able to use it without zooming in so much. I know there are answers for this scattered around but I thought we could consolidate some solutions.
Im using an HC1
Thanks

I am working on a special version for HC1. It's longer and would be much better for HC1. Thanks.

I use a condensor from optisigma and I have no vignetting at all. I get the same size as from my SLR camera. See some samples from www.kokokaka.com/35mm.

Le, do you have a trade in deal? :)
