I modified quite a few lenses recently and for large format are 170mm f/2.7 (kollmorgen) petzval and 175mm f/2.7 isco t-kiptagon double gauss with modified apertures and 3d-printed parts . they cover 4x5 @ infinity .

B&L 159.1mm F2 Super Cinephor on Maki Std by Nokton48, on Flickr
In bright key sun I can shoot J Lane EI 2 glass negs, at 1/125, which is the top speed of Makiflex Standard. Here a 9x12cm glass plate is loaded, this will be 9x9cm on 9x12cm material. These happen to be Voigtlander plate holders, I have many kinds.
Camera mounted and balanced on Manfrotto Monopod, ready to shoot. It's a GOOD workout to carry this beast around. Monopod a necessity I think as I get older.
Bokeh and DOF/"look" is amazing. This is a theatrical projection commercial 35mm and 70mm commercial motion picture type. This lens will focus out to about 25 feet, enough for my uses. Intend to do some portraits soon.
I used JB Weld metal epoxy to glue the lens to a board with correct size hole. This lens will fit on Makiflex Standard, but not on Automatic Makiflex deluxe model.

Thanks for confirming that. I'm a bit forward focused, so I will repeat the test. I'm confident I can get a better result. Time to get out the groundglass back and magnifier as a double check. I used a double sided Linhof plate holder, with spring loaded pressure plate.
It took four exposures (film is 25 years out of date!) but at least now I now know the correct longish exposure.
Developing by inspection by safelight is very fun for me. I just bought fresh Ilford Ortho in 4x5 and 8x10.
