Red & green outlines in photos

[Jzero]

Hello - I am new here and thanks for having me.

I am having problems getting good focus with my 5D Mk II and I have just noticed that there are green outlines on left of objects and red on right edges. This occurs where there are strong contrasts especially between dark and light colours.
I am using a 24-105 mm 1:4 L IS USM lens.

What could be the problem please?
Feeling devastated.

Ebiggs.

Yes, I love this combo too! Would have bought a Mk IV if I could have, but the Mk II, with this lens, has really helped my photography.

On my website, all the photos were taken with Mk II and that lens (the uni gear), but I can't seem to get the same detail with the camera and lens I bought. I will take it into a local camera repairer and ask for their opinion.

I am starting to wonder if the Image Stabiliser on the lens isn't working.

Hello Waddizzle,

Thanks for the sample shots. Single colour purple in those images and I can see it in a fair bit of the image (?).
My lines are green and red with green always at left and red on right of objects.

Hello jrhoffman75,

Photoshops CS6. I would appreciate to learn how to remove it, thanks.
I mostly convert to black & white but the fact that the problem is there is worrying. In the bl&wh conversion, the lines will still be visible at 100% I imagine, as lines that shouldn't be there.

Thanks.

Hello RobertTheFat,

Who knows if has been dropped 😞
But yes, I will have it looked at and may even send the lens off to Canon.
Could be an alignment problem, as the green and red look like a colour image with incorrect registration.

Thanks.

Here's one way. Others may have additional advice, since I am not a Photoshop user.

"Photoshops CS6. I would appreciate to learn how to remove it, thanks."

PS opens all Raw file in ACR. In ACR there is a CA correction tab.  Just click it and it is pretty much self explanatory. The free form Canon DPP also has a CA correction tool that works very well.  It is free!

CA is in the lens itself. It will be there regardless of the IS being on or off.  It should be easy to tell if the IS is working properly.

Would not be my first choice for lens repair unless Canon no longer services this lens.  Call Canon 1 (800) 652-2666

Hi Waddizzle - I can see the green in those images. Yes same problem I have.

Hello ebiggs,

The lack of sharp focus makes me think the IS isn't working. On the uni Canon/lens the difference in focus was very obvious with IS on and off. But in this camera/lens, I can't see a difference.

I won't get the camera repairer to attenpt to fix anything, but they will be able to tell me if focus is a problem.
I will then send to Canon for  repair if needed.

Thanks for all your help. I wasn't aware that CA was a common problem nor that it could be easily fixed.

Again thanks 🙂
