Lens Impression


I think it should be taken apart from some middle/large format camera, but the details are still unknown. Fortunately, it has shorter back focus length than I expected, I could get the infinity position using the helicoid ring of Pentax 6x7 and with small addition.

I took a walk around my house to make some trial photos. The pictures it made are very neutral. I also can see rather sharp edge in the shape of bokeh which I originally expected.
