Originally posted by Urkeldaedalus That ISO 2500 shot on Winder's link isn't that impressive to me, especially in the hair detail. Still, I imagine if I bought a M4/3 camera even with this apparently improved sensor I'd still mostly expect to shoot at ISO1600 or lower, and that would be fine for most applications -- sort of how it was with my K-7. That ISO2500 shot would still be useable in a lot of different situations.
The guy converted it from RAW to a JPEG using Faststone, so I'm not sure how that would compare to LR or C1 in terms of noise and detail retention. Looking at the GX-1 over one DPR the M4/3 sensor is definitely better than the K-7 and matches the performance of the Canon 7D. When we get actually support for the new E-M5 RAW files we will see how good it can get. For what it is I think it is pretty good
What are the expectations for a 4/3 sensor and a $1,000.00 camera? Clean 3200? Just 18 months ago Pentax users would have been thrilled to have an APS-C sensor that performed this good. The K-5 has set the bar pretty high in terms of IQ and compares well with older FF cameras.
With lenses like the 45mm and 12mm Olympus is making a pretty capable & compact system.
