I guess I'd say that low light is in the range where it is challenging to get a clear photo, hand held, even with a K-5. Looking at this chart, which only goes up to ISO 3200: http://www.fredparker.com/ultexp1.htm#EXPOSURE%20FACTOR%20RELATIONSHIP%20CHART%20B It looks like that's somewhere around EV -1, or EV 0, maybe as high as EV 1. ISO 3200, 1/8 second f/1.4 is EV -1 I'd say that dim light is in the range where it would be challenging to get a clear shot, hand held with one of my film cameras ISO 400, 1/30 second f/1.4 is is EV 4. It is my gut feeling that up until the current (soon to be previous) generation of u4/3 they were probably OK up to about EV 3. The current generation is probably good to EV 2, maybe 1 before things start getting rough. Most of my experience is based on looking at one or two other people's photos, so I'm not going say my figures are exact. But with the current generation sensors, and the faster shorter lenses available in u4/3, their low light ability is close to that of a K-5 thanks to the extra stop of speed you can get with the f/0.95 lens, and focus peaking for low light focus. > > G > > On Oct 9, 2013, at 7:02 PM, Larry Colen <[email protected]> wrote: > > > ...
