A beginner asks:

Regarding the 210 APO Symmar lens and Copal 1, to disassemble the front and rear lenses from the shutter, is there a 'catch' that needs to be released before unscrewing the sections--or, simply turn until they come apart?

thank you!



ps: any informed commentary on its use with a 4x5 Speed Graphic--e.g., quality of results, tips on superior shots with this lens, etc., are gratefully received...
