Found another nice looking lens from a dump – it’s in a good condition, could be from an OHP or such…
So, I cleaned it and made a simple cardboard lens board to be able to use it on a view camera…
Tried to figure out the focal length and aperture… I put the lens on Tachihara 8×10 camera and made some viewing tests. The focal length seems to be 300 mm and the aperture about f:5. So, a nice and fast lens — and will easily cover 8×10, allowing quite a lot of camera movements too! I’m hoping to use it for wetplates some day.
By the way, the lens measurements were done with a view camera TTW (“Thru The Window”) ðŸ˜‰ , because it is so damn cold outside: -25 C / -13 F.
Finally got my acrylic sheets — 5 mm thick and cut to sizes. All I had to do was glue the pieces together (with Acrifix 106 adhesive) to build my silver bath tank. The glue has now fully dried, and after the first tests the tank seems to hold water, with no leaks! ðŸ™‚
