I am looking for a Mamiya 250mm f4.5 lens for the RB Pro S, in excellent condition.
Does anyone have one of these.
Thanks

I own a 330S camera, and I'm looking for a different type of focusing screen.
The type I would prefer is the Type B Rangefinder (split image) 4 degree, if not the B2 6 degree.
I'm finding the standard one that I'm using is not the best to focus with, and I have had a few prints back that are not as sharp as I would have liked, I know it's not the lense as some have come back pin sharp and I'm sure it's not camera shake.

Preferably a second hand one as I cant afford the expensive types that I have seen on the net.

Hope some one out there can help.

Thanks
