I only used this a couple of times. It has extemely low coma, just a bit of CA when fully open. Easy to correct.
I think the attached image is the only one that I used the lens for. I am divesing myself of all my Canon gear.
For some reason AM makes the colors look horrible. I can send a link to the original image.
