Originally posted by dgaies What's the point of getting all worked up about in camera JPEG images where there was clearly some heavy handed NR. Have you considered taking a look at some of the RAW files?
The RAW files don't impress, either; you get back some detail and quite a bit of noise to go with it. Did you think there was some magic in the RAW files that Pentax cleverly worked very hard to destroy in their JPEGs? Even the RAW ISO 800 K5 shot doesn't look as good as the Nikon D3
JPEG @ ISO 6400, much less the RAW file (the K5 RAW
noise looks better
when comparing K5 @ ISO 800 to D3 @ ISO 6400, but that's obviously because they're applying noise reduction to the K5 even in RAW, and even as low as ISO 800 (that, or it's just
that bad in terms of the mushy detail at ISO 800; again, check the red leaves on red fabric, which shows lots of detail loss even as low as ISO 800 on the K5, and even in RAW), while the D3 is NOT using noise reduction in RAW. The D3 RAW sample also has some slight overexposure, which detracts from its appearance).
In short, noise reduction mush does not an impressive performance make. The K5 is still stops behind three-year-old Nikon D3 performance, and is nothing to sing from the hilltops about. For the record, I'm not the one getting "worked up;" that description would be better suited for those braying on about the K5 long before any actual comparable images taken under similar controlled conditions were available, with all of the ridiculous assertions of "practically equal to FF" performance absent anything to support it. Now let the crow eating begin, though I'm sure the more likely response will be either deafening silence or rationalization, conspiracy theories and/or excuse-making.
