Does anybody have any experience with Pentax 67 focusing screens?
I got a second focusing screen and fresnel lens with my pentax 67 a beattie intenscreen with split image.
However, when trying to install the beattie screen with the second fresnel lens (which looks a bit weird in itself, having weird circular reflections on it) I get a bright center but a drastic falloff of brightness towards the edges.
With the stock fresnel lens ( i suppose it is the stock) the falloff is even worse.
With the standard focusing screen, image is same brightness all over.
Which way should a fresnel be installed? rough surface towards mirror ur up?
And the beattie instructions that come with the screen says that the original focusing screen comes in 3 parts (matte screen, fresnel and glass), but there is no glass in my 67... neglectable or problem? Also the matte screen and fresnel of the beattie are also separated, should that be?
I would be glad if anyone could help me out here
