Mostly good experiences of MF-28 databack,I've used it continuously for = 2,5 years in F5 printing speed and aperture information between = frames,also date and time. Has happened sometimes that data has been = printed annoyingly to the picture horizontally. Can anyone explain why = it has happened? If I recall right those were mostly CH,CS and CL = situations(continuous high,silent,low)or similar. I've tried to register = names of shooting sites,but the one by one character selection is too = cumbersome to do in the field. Of many other features I've used Focus = Priority to observation shootings: birds coming to nest,wild animals = arriving to eating place,sailing boats passing by,not too easy,because = focusing most be very precise to the anticipated target. Focus priority = works best with a cable release pressed and locked.Requires about 1 sec. = time of the target to stay in the selected focus to activate the = camera.Just for fun I have also running number of shoots on,now showing = 10567.=20
