Patrick, Focussing screens made for the Contax RTS 2 fit perfectly. You can get a split image screen.I have one in my Viso 11
I believe Beattie Intenscreens offer an alternative for the Visoflex as well. Contax screens should be fairly cheap on the "used" market.
Patrick, if, say, you want to take photos of postage st&s, butterfly wings,blood s&les, etc. you could use a very old gadget called a Focaslide [Fuldy] to which you could attach a screw-mount lens.
Or another old gadget called a Boowu or Boowum, both of which are reasonably priced, particularly the Focaslide, which has gone out of style.
A focussing screen sounds interesting for the Visoflex. I have a Viso 3 with the 90Â° 4x finder, will it also work with the Contax screen? Just curious, I actually love the brightness and clarity of the Viso screen as it is, and it's capability to evaluate DOF.
thanks! Will find one.
Besides, is it very difficult to get a mint 4x 90 finder only? expensive? I have two but both are not in good condition in prism. It produces no enough light to help focusing with matte screen. Any useful tips on quick/easy use of Viso? thanks!
