I got a Nikon D800 not so long ago, and a 24mm 1.4 wide angle lens. The camera has an option to perform lens distortion correction if you have a suitable lens. Clearly, the camera can apply this correction if you are shooting JPEGS, but my understanding is that when shooting RAW, the raw image is left untouched and additional metadata is added to the RAW file. OK, if my understanding is correct, a suitable editor like Capture NX can then use the embedded information to modify the image accordingly. However, I've read that Aperture is blind to this information so cannot do this. But the really strange thing is that when I load RAW images into Aperture from my camera taken with the wide angle lens, they very briefly appear in what appears to be a mildly distorted form. Then after a short instant, the distortion goes away and the image pops into place, with apparently perfectly straight lines and no bowing. What's going on here, do you think? Am I imagining the image 'popping' and getting fantastic results from the (admittedly expensive) lens? Or is Aperture actually aware of the lens correction in some situations?
