Ektar 101mm: For optimal result what is the best f-stop?

greenspun.com : LUSENET : Large format photography : One Thread

I am trying to figure out what will be the best f-stop for the best optimal result using a 101mm Kodak Ektar for a 2X3 Speed Graphic Pacemaker. If anyone has the experience using this lense I will appreciate.

If you're using a roll film adapter, better stop down to at least f:16 for B&W or f:22 for color. For sheet film, f:8-11 is the optimum aperture for sharpness.

I have one that I use on my 45 Grafic with 23 film back and 22 film back, sharpness is good at all f/stops, the only thing that changes is deapth of field which increases as it is closed down, this lens is also very good on 45 for macro work. Pat
