You wouldn\'t want in-camera CA correction for raw files anyway. The whole point of raw is to record as much of the original image data that the camera saw; any corrections in post would simply be indicated as a set of directives to the raw converter, as is currently done.
But because video isn\'t recorded as raw, this feature is most welcome, as it can be applied on the fly without expensive frame-by-frame computation in post. And because it\'s also done for JPEGs, it\'s great for JPEG shooters, who presumably want to do as little processing on their files as they can.
Now if they could just make their fast-aperture primes with less axial CA, that would be awesome
Yes of course.. I was just thinking out loud.
Still, it\'s interesting to me as a RAW shooter, for this reason: In ACR, I enable this by default so that CA corrections are automatically applied. Buit in DPP, this is not so easy. CA correction is off by default, and you can\'t just select all of the thumbnails in a folder and enable it as a batch, because Canon applies its whole set of image corrections together. For example, if you *also* have vignetting correction enabled (the level of which is controlled by a slider), Canon will apply the correction level of the first selected image to the entire set, rather than the \"as-shot\" correction as required by each lens.
Obviously, this is lame software design and should be fixed. But at least with this camera the CA correction can be toggled in-camera, making it a set-and-forget feature (finally) if using DPP.
