I have a canon 20d which i bought in september of last year and after much thought invested in the 10-22mm efs lens as i'm a keen amateur architectural photographer and i was visiting the burj in dubai. However i have noticed a considerable amount of chromatic abberation specifically on circular forms almost 3 pixels in width. I have used CS2 to adjust some of my images in the raw state but was wondering if anyone could give me any thoughts on if this amount of abberation was normal? and if not how do i create a test to send to canon?
Thanks
