favorite LF and ULF lens if you had only one lens

[Doremus Scudder]

I'll say an f/6.3 Kodak Wide Field Ektar with the appropriate focal length for the format.

+1

My favorite and most-used lens for 4x5 is my 135mm WF Ektar. Sharp, small, and coverage that you can't get in a Plasmat. I'm surprised this design disappeared so early. It's a real winner in my estimation.
