<Could someone explain me briefly the basics of the cables MC-27 and MC-20 with F90x?> The MC-27 is a Datalink cable and was used with the original DataLink system to connect the camera to the Sharp Wizard Organizer. The MC-20 is a 32" long remote release cord and permits both remote fiiring and long time exposures up to 10 hours. (Requires a CR-2032 battery.) The MC-30 is also a 32" long remote, but does not offer any additional features. Neither remote cord requires a data back for operation. regards, Henry Posner/B&H Photo-Video http://www.bhphotovideo.com
