Hello everyone, Very happy to join the list again after 2 month away. As far as I know, the MR3 is a mechanical shutter release for MD12 motor drive or N 8008 body. I have an opportunity to buy a MR2. What is the difference between MR2 and MR3 ? Thanks in advance for any quick help. *************************************************** Fabrice Joly 17 rue du General Gouraud 69008 Lyon - France Tel/Fax : 33 (0)4 72 72 92 15 ***************************************************
