RM-2, HC-3 70 Prism enlargment

[blowupster]

HI,
These heavy prism viewfinders are for sale for peanuts now. Perhaps I'm interested to get one to test, however I'm interested only if the enlargement is close to standard viewfinder ...or more.
The goal is to use it with CFV-39 for vertical shooting.
Strong enlagment helps to get sharp images.

I have the HC3-70, and the HC-4 Prisms. I like using them, magnification is good with the 500C/M. You must align your eye with the viewing tube, or the image blacks out. Not difficult, but takes some getting used to. A good product, I was using the HC-4 last week with a regular (very old) microprism screen, and the C 40mm F4, and it worked very well. The HC3-70, I use when I am shooting 70mm film. (Yes I still shoot 70mm film, and I like it!).
