100 mm field of view on the Vitessa T?

[Eugen Mezei]

Got me a Voigtländer Vitessa T with the 100 mm 4,8 Dynaret. Unfortunately without the Turnit finder 3.
For the Kiev 4 exist the approximation that the rangefinder spot is around what the 135 mm lens sees. Is there such approximation for the Vitessa too?

I checked mine- the Patch is square more than rectangular and is fairly small, does not cover 100mm. I would look for a zoom-finder, they are not expensive. I have the Turn-it, also have some zoom finders that go to 200mm.

As a quick alternative: you could make a mask out of some color take or plastic sheet to g over the finder.
