Canon EF 2x III Color

Just curious if anyone has had this experience. When using the Canon 2x extender, in Post I see in a lot of photos more instances of blue & purple hues across the image forcing me to spend more post time correcting. I use the following,

Canon R6
Canon EF 2x III Extender
Canon EF 70-200mm F/2.8 USM II
Shooting RAW
DxO Photo Labs 6 for lens & noise corrections export to DNG
Capture One 23, import the DNGs to complete processing and subsequently the hue/level corrections, mostly blue & red.

Just curious as I don't see this without the extender ...

Thanks,

Tom

What you are seeing is chromatic aberration (color fringing), and it is common with teleconverters. The 1.4X v.3 handles this much better than the 2.0X, with the obvious downside of losing some reach. The only other way to reduce the fringing is to upgrade to the 70-200 III. Still, you are going to get some fringing in high contrast areas of the image no matter what lens you pair with a teleconverter. Rather than upgrading, I'd take the extra 3seconds to run it through Lightroom and use the de-fringe tool. It's literally one-click with the eye-dropper tool and the blue/purple is gone. I don't recall if CaptureOne has the same feature.

Thanks MMp, much appreciated. I am going to see if C1 can do it or even DxO which is the first step in my workflow ...
