I have for sale very mint Schneider-Keuzach enlarging lens f4 and 28mm. Which I believe is the proper lens for 35mm half frames. It is flawless no scratches no fungus no dust and even no marks on the barrel. The person I acquired this from used it to print large prints from 6x6 negatives on his Bessler 23CII. I also have the recessed lens board for it for a Bessler 23CII. How about $200.00 shipped CONUS. international okay but shipping will be extra. If want the lens board it will be $5.00.
Thanks for looking and I do donate a percentage of sales to the site.

I'm getting a little concerned this might be lost or stolen. Do you have a tracking number?

Received today. Thank you. Is the iris supposed to open all the way?

No. Open about half way at f4.

Okay, thanks. I was comparing it to some newer ones that appear to have nearly identical glass that do open all the way.

Newer versions of the same lens? I think they used a stock barrel and aperture mechanism for many of these. Yours, and mine, just have some stop built in to keep the aperture from opening beyond f4, and beyond the actual lens opening. Probably not hard to undo if it bothers you.

My Nikkor 80's are that way too, BTW.

Okay, thank you. I wanted to use this lens for macro so a faster aperture is beneficial for focusing and for limiting diffraction. Being able to open fully is a definite plus.

I assume they (and Nikon with my 80) had a reason to limit the aperture, and that reason might well be something like focus shift.
