Do you mean 135mm?

close enough, I cant put all focal lengths up.
What does it matter? Sharpness is only a tool for translating one's vision to paper.
What if you have an f/4.5 lens?
I asked because, frankly, I don't know of ANY 138mm LF lenses.

138/4.5 Graphic Raptar. But what its for is anyone's guess.
I have a 135mm Schneider Xenotar which is pretty sharp edge to edge even wide open at f/3.5, it only gets better stopped down. The lens seems to excell at around
f/11 or f/16. This has long been my favorite all around lens for 4x5.
