Title: Chromatic abberation 10 -22mm EFS
Post by: naeboer on February 07, 2006, 08:00:56 am

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

"In absolute terms CAs can be noticeable at 10mm and 14mm where they exceed an average pixel width of 1 pixel at the borders".

It seems that yours is not a typical sample.
