Thanks. I shall learn more about it soon. The E-M1 should arrive on Tuesday. I hope the EFC firmware update is already installed.

Yeh,
Lots of good stuff. Firmware update enabled an EFC--labelled as 0sec
anti--shock. Limited to 1/320 or slower.
Wonder if Oly  will enable the "super-resolution" multi shot protocol
when the sucessor to E-M5 is released.

Superresolution (SR) has been around for a number of years and more
recently example based (from single image) can be combined with the
standard multi-image technique relying on sub pixel misallignments for
further apparent resolution gains. This depends upon the fact that many
images have areas that are very similiar both on the same scale and
different scales. Combining techniques reduces the chance of the single
image scheme from falsely "hallucinating" details that are not really
there.

I am not not sure that Photoacute does this but it might ---as under
perfect conditions up to 4Xincrease in apparent resolution noted.

See paper out of the Weizmann Institute:

Perhaps hallucinating that anyone is interested in this on a Fri eve, Mike
