1) Congratulations on the megaflash bulbs, as I understand it they are the
finest flash bulb manufacturer on earth.
2) could you work out your calibration problem by just setting the the focus
knob to say 3 and seeing if items in focus are three or nine feet away?
3) Given the amount of light put out by a typical megaflash bulb ,surely all
you have to do is set the focus to infinity and fire away?
All the best
