I need some help, please:
I bought a new Tokina 12-24mm lens for my Eos 60D.
The lens is sharp, there is nearly no vignetting, BUT there is a lot of Chromatic abberation, heavy chromatic abberation, at 15mm to 12mm. red and blue lines on the end of the edges.
Does anybody have the same problem?
What can I do? The lens has the problem @ an aperture of 4 to 22, @ 4.0 it is really heavy.
How can I correct the CAs? Is there any possibility to do so automatically (Canon DPP lens recipie), or do I have to correct it manually?
The same problem at my wife´s 7D.
