Nikon announced a service update to Capture NX 2 today, with the release of version 2.2.5. While the main purpose of this update is to add support for D3100 NEFs, there are a few fixes and new features.
Most notably, the feature I welcome most is the addition of new lens distortion correction algorithms, including support for the 70-200mm f/2.8 VR II and the 16-35mm f/4.0 AFS VR. I’m not sure if the newly announced Nikkors, like the 24-120 f/4.0 VR, 85mm f/1.4 AFS, etc. are supported, as those lenses are not yet available. Nevertheless, the addition of distortion correction for the 16-35mm is most welcome, indeed. Also listed is official support for Mac OS 10.6.4. Whew.
There are a litany of Picture Control caveats with D3100 NEFs and NEFs created when using the Mode I, Mode II or Mode III Picture Controls as camera defaults. The language was fairly unclear on Nikon’s page, but I don’t expect any issues for most users.
One note: if you have Nik Color Efex Pro 3 installed with Capture NX2, you’ll want to uninstall and then reinstall; otherwise the filter names in the drop-down menu will get corrupted. Reinstalling the CEP 3 filters corrects this issue.
(Update: this may only be an issue on the Mac OS version; I’ve heard user reports of no issues on Windows. My advice is to install the update, check your CEP filters in the pull-down list, and see what happens before you uninstall anything).
