the pentax67 SMC 150mm lens mounted to Horseman L45, image circle is insufficient but anyway it works
the gallen optics China 120mm f2.8 large format lens. It was a rehouse from an instrumental optical lens which hard to know the original supplier and technical data. It is 4 group 6 element double gauss design and covering more than 4X5 at wide open, with insane sharpness on 4X5 film at f2.8. I rebuilt the housing with aluminum and mounted it on COPAL 3s shutter. Acutally the original modification which built with 3D printing had been tested for more than half year. We were shocked by the performance and now made it into metal.
There were still some lens available and if you have interest, let‘s discuss !

From my first batch of 4x5 negs. Gonna need a better scanner... my HP document scanner doesn't seem to have enough DR to get the cloud details. Also the sharpness of the scan is so low that I need to rescale from 1200dpi to 600dpi and apply some unsharp masking to get a nice picture. (I can clearly see the bricks on the building on the neg with my 10x loupe!)
