Which Knight Optical Condensor lens for my Agus35?

Hello,
This is my first post here, HELLO EVERYONE!!!

For the past week I have read all the Agus and Aldu 35 adaptor posts, and I am very excited about all this. Thanks everyone on here for there hard research and work. I have done some tests with a basic Agus35 prototype. All is working enough for me to know that the concept works, now i need to go about improving things....

I get bad vignetting, so am under the impression that i need a condensor lens to 'collect' the light? I am in the UK and have found a company called Knight Optical that I can order from. I have read that the condenser lens focal length should be equal to or more then its diameter, so could you guys have a look at their webpage and give me an idea of my best choice? I am looking for a 50mm diameter lens:

That is a link to their Plano convex lenses, but they also have many other catergories here:

I am thinking about the 50mm dia 63mmFL one for 22.25 on the first page, but if you guys have any sujestions, that would be just great!!!

I hope to get some footage up soon!!!

Cheers,
Wayne.

They are probably really good there, but expensive - surplus shed used to have alot more - under $10.00 - I don't know where they have all gone! Maybe they go under a different name - like achromats and objective lenses.

Thanks for your reply.
I want to stay with a UK suplier if I can. There are so many different condensors on this site, its hard to know which one to pick. it has a section for condersor lenses, but also another section for planoconvex lenses.....are they not the same?

Please guild me to the correct lens...

Thanks
Wayne.
