TheRodenstock Sironar-N 150mm f5.6 is a very compact “standard” lens for 4×5 cameras. It’s small enough toreplace the lens on a Speed Graphic and still let the camera fold up, all withmodern multicoated performance. Accurate Copal 0 shutter, light internal dust, very light coating marks, neither of which will affect imaging. Includes front &rear caps and retaining ring.
