If you thought getting to the maintenance menu for the EX1 was a pain, check out the following procedure needed for the EX1R. This is what to do if your back focus is off:
LCD must be in the closed position
LCD back light switch (under top handle) must be in the OFF position
Gain switch must be set to H (high)
Press and hold Cancel + Jog Wheel, then + Menu
Maintenance, RPN and Information Menu items will be added to bottom of Menu below “Others” menu
Flangeback auto adjustment (also called back focus) is under Maintenance, shown as Auto FB Adjust
Procedure for actually carrying out the adjustment is the same as the EX1–
An 8″ or larger Seimens star chart is ideal. Siemens star — Wikipedia, the free encyclopedia
It should be mounted on a plain wall, wide enough to cover most of the frame at full zoom.
Don’t have anything else on the wall that will be in the frame on full wide. High contrast objects within this field of view may effect the calibration
Mount the camera on a tripod, about 10′ away from the high contrast back focus target
Zoom all the way in to the target and center it in the viewfinder
Set lens to Auto Focus (focus ring pushed forward), Auto Iris, Auto Zoom, Macro Off.
Select Auto FB Adjust in the Maintenance menu
Don’t touch the camera until the procedure is complete.
Many thanks to the various posters at DVinfo.net for the instructions. Oh yeah, you can find some great free test charts here in PDF format. Happy flange back adjusting.
