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.

But the central dot is out of focus.

But the central dot is out of focus.

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It took four exposures (film is 25 years out of date!)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.

That isn’t a film holder, it’s a glass plate holder and that isn’t a pressure plate, it’s a spring loaded spacer so it can also accept sheet film. That ejector lever is there to get the glass plate out without scratching the emulsion. It also ejects sheet film.

Hey Renditiont
I really like the look you are getting with the Pentecon 6 and the projection lens! If you could give me a little more info into what helicoid you used ect. , I would be most appreciative 😀 David
