I know people say that Aperture automatically corrects distortion for m43. I've been using m43 for about 4.5 years - first a GH-1, now an E-M5 - and it has been my experience that if it does such corrections, it does them very badly. The Panny 14-140 is well known for epic vignetting at long focal lengths. When I imported RAW files shot with that lens, the vignetting remained. And the Zuiko 12mm on my E-M5 is famed for barrel distortion if uncorrected; it is very visible when I import my RAW files to Aperture, but I cannot detect it when the same files are viewed in Lightroom.
I therefore conclude that if Apple claims m43 RAW files automatically have lens corrections applied on import, either the claim is untrue or the functionality is very poorly implemented.
1) Nobody is claiming that vignetting is something that is addressed by Apertures lens correction... there is a devignette tool in Aperture.. never had cause to use it so can't testify to its capability
2) I dont have the 12mm , so I can't run the test that would prove that Aperture applies the same lens correction as the camera would if it was shooting JPEG - namely shooting RAW and JPEG and importing both into Aperture and see if there is a difference.
3) Aperture and Lightroom take different approaches to the issue of lens correction. Up until Aperture 3 there was no lens correction in Aperture at all, after version 3 there was support for the corrections specified by the lens maker embedded in the RAW file. Lightroom on the other hand seems to offer a deeper level of identification and control based on a lens profile and adobes interpretation of what needs corrected
4) Aperture does do lens correction... maybe not the lens correction you want... but don't deny it does it.... also curious how you claim to have been using micro 4/3 for 4.5 years starting with a GH-1 when the GH-1 was only announced in March 2009....were you a Panasonic beta tester
