				| I have a 2x3 Speed Graphic with a 101mm Optar. I just purchased an RH10 (6x7) roll film back and I was wondering if I should change the viewfinder mask or just stay in the center of the field. The chart on this site doesn't seem to cover this particular combination. Thanks! |

				The "correct" mask for this lens/format combination is the no. 2, but be advised that the no. 2 is proportioned for 6x9, not 6x7, and there is(was) no mask made for 6x7.  There was a recent thread here on this very topic; see   http://graflex.org/helpboard/viewtopic.php?topic=4420&forum=1&6

				| Thanks. I was using a "23" back and avoiding the edges anyway, sounds like I don't really need to change much. |
