Sinar DB mount Copal #1 4x5 lens board
I am not a Sinar guy (at all), however I recently obtained this Sinar DB mount Lens Board with a lot of Toyo gear that I purchased.
I was able to confirm that a Copal #1 lens fits the front threads.
On the rear there is an armature that moves the 5-blade aperture and the movement seems smooth and has a spring return. Based on my measurements of the smallest aperture and assuming f45, the 3mm hole would imply that this board can be used for a 135mm lens.
Upon visual inspection, it looks fine, however I have no idea what a complete or incomplete setup would look like.
I had considered using this as a modified board to mount a medium format bayonette, considering the hole is pretty large and it seems as though a few screws removed would reveal just a plain board with approximately a 100 mm hole.
