I have been happily using APG with my Nikon D700 for some time. I now have a Nikon D4s - which is a new model. APG doesn't stitch the .NEF files. It doesn't detect a panorama. If I convert the .NEF's to .tif - all is fine. I had a similar problem with 'Lightroom' and the new D4s - an updated version of Lightroom resolved the issue.
When will APG have a software update to allow it to handle the .NEF's from the D4s?
