Lens profile for Z Nikkor 14-30 F4

[ThomasZ]

Hi all,

I'm looking for a lens correction profile for the Nikkor Z 14-30 F4. That lens is on the market for a long time now, but I'm unable to find a profile. I've checked the database at https://github.com/lensfun/lensfun, without success.

Any help? 

Thanks,

Thomas

Hi Thomas,

I can't speak to their quality or accuracy, but there are some pending user submissions to LensFun for this lens:

- https://github.com/lensfun/lensfun/issues/1054
- https://github.com/lensfun/lensfun/issues/1404

I have combined them into a single XML LensFun profile (attached). If you go into Preferences > General, then "Open lens profile folder", put the XML file in there, then restart Photo, that data will become available in the app.

Hope that helps!

Tom,

Thanks for this file. It is very helpful.

 

Would you happen to know when importing a .NEF file directly from the SD card to Affinity, if lens correction has already been applied by Nikon? I'm trying to find a way to view the unaltered file before any corrections have been applied by Nikon. 

 

Thanks!

You can't view the unaltered file because in a RAW file there is no tangible image in it to view (other than possibly a thumbnail preview) before it is developed. For a full explanation of this see the Affinity Spotlight article, RAW Actually.

See related:

• Nikon Electronic Format (NEF)

So as the NEF is Nikon's RAW data, a NEF file contains all the image information captured by the camera's sensor, along with the image's metadata (the metadata in turn contains the camera's identification and its settings, as the lens type used and other vendor specific information). - Thus for NEF files on the cam's SD card, there haven't been any lens corrections applied so far. Instead just the lens specs/settings are defined inside the metadata portion of a NEF file, and that portion will be interpreted by a respective RAW converter software (for example Nikon Studio, CaptureOne, DxO, Lightroom, Affinity Photo ... etc.) which then applies the needed lens correction for the RAW (NEF) image!

Ah! So it IS the software that applies the correction. Thanks for the explanation.This has been really helpful.
