Just wanted to say thanks to @joxby for the awesome donor project!
I'm now looking at lens options for an ultrawide conversion :0)
Some nice machining on the Beiber one.
Now, do I make a Holgawide or a Bronica Mod :0)

I've been looking at donor lens options briefly tonight and agree that a TLR lens is probably the best compromise of cost/size.
Ive got an old Yash Mat in the cupboard thats jammed up but the lens is fine.You can have it if you want mate.

PM me your address and I'll get it in the post tomorrow. Don't worry about postage, get me a pint at the next meet.
I saw your posts on there because I was being promoted to moderate them :0). I haven't had chance to look at it properly yet bough. I'll see if I can add anything to your suggestions later.
