Hi there,
Fun product. Here is my reading of the instructions you have included.
The lens you need has to be a macro one (it has to focus on an object 9" away.
The 50mm f3.5 or 50mm f2 will focus this close. The next problem you have to
solve is the angle of view. I suspect the 50mm may be too wide from what they
are saying. They suggest a 60mm in the text below.
In your experiments so far has the 50mm you tried provided a full frame of the
two edges of the mirror? If so then you need to find one of the two lenses
above. You should also be able to work with a macro focusing short zoom lens.
That one would provide you with some scope to fine tune the angle of view
problem (assuming the zoom is macro capable across it range of focal lengths,
not all are).
The key is to be using a macro lens as I far as I can see you need to be
focusing on the mirror and not the reflection in mirror.
Hope this helps.
Dan.

Underneath is an excerpt from the EyeSee manual.
Note that the distance between subject and camera
must be between 9 and 18 inches. The required
depth of field is 2 to 3 inches.

Hopefully someone on this list can point me in
the right direction. Any advice is welcome!
