i = This flash is incompatible with the manual focus bodies! It has the same control interface as he F-type flashes, but it has no 'F' in its name, probably because it does not support any functions other than TTL.
ii = Comes only with a 49 mm mounting adapter, but step-up and step-down rings can be used to adjust the mounting diameter as needed.
iii = there are three operational modes: all 4 bulbs, the 2 left-side bulbs only, or the 2 right-side bulbs only.
