I suspect that these ‘scopes are an F5 to F7 design and to allow for their close focusing, typically 3 metres, part of the eyepiece body has to protrude into the ‘scope body.

We also have the Leica photo adapter that converts the ‘scope to an 800mm F10.4 telephoto lens but this adapter is approx 6 inches long (150mm), placing the DSLR quite some way from where the eyepiece position normally is.

I think it is a tough ask unless Vixen have some accessory made for the job?

Hi again Dennis,

Yes the Vixen is roughly an F5.6 (450/80). It wouldn't worry me too much to have to use a long extension photo adapter if Vixen had one at a reasonable price - I haven't seen one referred to but will have to ask them about that. I assume the Leica one sits in place of the EP, so it too presumably has a lens element very close to its front end much like the EP does, to meet the focal plane.

Cheers,

Andrew
