Although Olympus does not recommend this combination, using their own
quality standards, many of us have used it because it still produces
very acceptable results. The only drawback is the slow F9 speed that
makes focusing much harder than the bare lens or the 1.4xA combi.
Tripod highly recommended although hand-held in plenty light conditions
is still possible @ 1/1000 sec. using 400 or 800 ASA.

This can happen because of the narrower angle of the lens with 2xA
combi giving you some spot metering as compared to the bare lens; when
you aim it at an object that is brighter than the average of he area
covered by the bare lens you still may get the same shutter speed. A
true OM-4 spot metering on the same area with the bare lens and with
the combi will tell you that the converter actually did cost you two
stops.
