I canít seem to keep a crisp focus from top to bottom on my new (used) V35. Iíve followed the instructions several times but find the image moves slightly out of focus when I lower the head after resetting the focus as the manual says.
I played around with the lens housing but that didnít make much difference. Should the lens housing be tight against the negative stage or should it be snug leaving the focus ring ease of movement?
Just wondering if any V35 veterans out there can give me some advice.
