CA with Tokina 12-24 vs. aperture
Mar 4, 2006

I have been following threads comparing the extra wide zooms for months now. Now that PMA is over, with no new lens announced, I'm about ready to spring. I am mainly interested in shooting landscapes with the wide angle.

The Tokina sounds pretty good except the CA at the wider angles. I'm wondering if the amount of CA is a function of aperture (I'd anticipate the majority of my shots at around f/8.) Also, Iv'e seen reference to correcting CA in PP. I use NC 4.4.1 and Photoshop 7.0.1 (Mac) but don't see tools explicitly dedicated to CA (unless this is an ancillary function of the Vignette Control tool in NC).

Thanks for any help,
