DPReview posted their studio scene tests for the Nikon D7100. See here: http://www.dpreview.com/previews/nikon-d7100/7
I compared the D7100, D5200, D7000, Olympus OM-D E-M5, and Pentax K-5 IIs. Here are my observations:
- The D7100 is slightly but noticeably more detailed than the D5200.
- The D7100 looks about the same as the D7000, but the D7100 image is larger, so more details are preserved at high ISOs.
- The Olympus OM-D has much more chroma noise but has similar amount of detail as the D7100.
- Notwithstanding DXO's scores for these cameras, the Pentax K-5 IIs looks significantly better than any of them - more detailed, with less noise. To me, at high ISOs, the K-5 IIs looks about 1 stop better than the D7100, D7000 or D5200. This was very surprising to me because the K-5 IIs is based on the same sensor as the D7000 (except that the K-5 IIs has no low-pass filter). Well done, Pentax!

UPDATE: I downloaded the studio scene samples and compared them at the same viewing sizes: Nikon D7100 High ISO comparison with D7000, D600 and D700

As far as I remember, in previous Pentax models noise reduction was automatically applied even for RAW files at higher ISOs, I believe this could be the reason why the files look smoother than the ones from Nikon. Worth checking, though, whether that still applies to the latest KIIs.
ReplyDeletePS. Here's relevant link talking about Pentax noise reduction for RAW files:

Funny, as far as I know, this cannot be switched off.
Hi there! Thanks! That's very helpful to know! I didn't know about that regarding Pentax raw files. That really helps explain the results.

hello once again,
ReplyDeleteI have found information on LensTip.com that RAW noise reduction is also applied in latest Pentax DSLR models. That explains everything. On the other hand, K5 is a pretty good camera anyway :)
