Sorry I didn't get all this in the other msgs: 

The 45mm ApoGrandagon 

SPECIFICATIONS OF RODENSTOCK GRANDAGON N SERIES LENSES 
                Lens 				45mm 
Aperture Range 				4.5-32
Shutter Type 					Copal 0 
Maximum Recommended Film Format (In.) 	4x5"
Angle of Coverage at f/22: 			110° 
Image Circle at f/22: 				131mm 
Filter Size Ø 					58mm 


And here the spec's for the SCHNEIDERSuper Angulon 47XL

SPECIFICATIONS OF SCHENIDER SUPER ANGULON XL LENSES 
Lens 						47mm 
Aperture Range 				f/ 5.6-32 
Shutter Type 					Copal 0
Maximum Recommended Film Format (In.) 	4x5" 
Angle of Coverage at f/22: 			120°
Image Circle at f/22: 				166mm 
Filter Size Ø 					67mm 

NOTE the much larger image circle, allowing more movement, wider angle of
view and the larger filter size (to accomodate image circle and angle of
view) on the Schneider.

	You get what you pay for.  In this case Schenider wins.
