yes absolutely jim, the low light /high iso ability of the OMD is far beyond that of any PEN, qnd may end up being competitive to the X100. and i also agree the handling of the camera in general, its speed and varied functionality, as well as compartive kit lenses are all far superior with the OMD. my niggling concern is specifically comparative IQ/resolution in good light at lowest iso (200).
after reading all the great OMD reviews i realized most of them really concentrated on the OMDs low light ability. only lori grunin from zdtech spent a little time on low iso good light IQ and summarily concluded it wasnt much different than the PENs. at first reading i thought she must be nuts, but that seems to be what i'm finding so far.
being somewhat frustrated/disappointed in this result, i'm curious as to others perceptions. then yesterday i recalled reading somewhere that the OMD somehow shoots 2/3 under the chosen iso, meaning when set to 200, one is actually shooting at 125. my understanding is that most contemporary digitals are optimized to shoot at iso 200, so to 'compensate' i started shooting at iso 320 with the OMD. i felt i got better resolution, though since yesterday was very rainy, i only took about a dozen photos, so not enough of a sample.
i also feel i'm getting many more blown highlights in bright daylight than i did with my PEN. they do seem to be recoverable, but i keep fiddling with different settings to deal with this phenomenon...
