these was the same day but the pictures are taken with Kodak Aeroektar 178mm f2.5. This lens was regarded as a common initiative lens of hyper bokeh on 4x5 format, with the speedgraphic. Making a 35mm equivalent f0.68. Different to the 3G4E structure, the AE is a typical double gauss design, the bokeh is still my favourite style. These 3 pic are also with the kodak aerocolor film 2460, an aero with aero photo
The image circle of SMC165mm is much bigger than 150mm, but not enough for 4x5 at infinity. The element is mounted on a COPAL3s

this is a famous extra large projection lens made in China. It was used to project reflex document which the function was similar to leitz EPIS. But this Nanjing JTS 340mm f 2.4 is double gauss design and has an ultra speed at f 2.4. It can easily cover 8x10, even up to 11x14 inch. but the element is sooooo big even the diameter of last element is > 140mm. Using this lens require a very large front unit like arca 171mm spec. and a very big curtain shutter larger than 5x5inch. Till now I only shoot it once , and using a smaller shutter which affecting the real aperture. Willing to fix all the problem and experience the full power of this 340 2.4 on 8X10 format
The completed camera and associated kit. The little lens case I had laying around and fits the lens perfectly. The first successful negative is shown on the little light table.
Here's the lens mounted on a box of fortuitous dimensions. I had planned on making something from MDF and styrene sheet I had, but this box fit the bill perfectly. I thought I'd use a piece of velum mounted on foamcore for a focusing screen, but a glazier gave me this piece of ground glass. Laminated sheets of paperboard place the glass at the film plane register of 4.8mm.

Just plain sturdy. No batteries or lens. 4x5 sheet film holder. 79mm focal length, .020 in. pinhole. Am going to go to a smaller pinhole for longer exposures & some strobe painting experiments.
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 !
