For use with a Durst 138 S which is now set up with a CLS-301 head etc...- expecting a head for 8x10... are these two lens equal in quality: RODENSTOCK Rodagon 240mm f/5,6
thread size on the back is 72mm thread - seems an issue with the 138 S turret, or a: Rodenstock Apo Gerogon 9/240mm M50X0.75 thread compatible with a Durst Lapla plate. Thanks, - Brad
