Canon 70-200 - focal plane loss

JazzJ

Hi all,

 

Hoping someone can give me some advice. I am shooting on a Canon M50 with a Canon 70-200mm f2.8 IS USM II. Recently, I have been noticing a loss of focus/ some soft areas in my images. I can't decide whether it occurs at a certain aperture or focal length, or if it's just something very weird. See below the images as an example.

You can see the surfer taking off on the wave is sharp, but the surfer on the right hand side is soft. Basically, from that position in the frame, it's all soft. Almost 1/4 of my frame. It doesn't bother me too much, but it's something that I just can't wrap my head around.

 

Any advice welcome.

 

TIA

Here's the two surfers in a screenshot from DPP and the downloaded .CR3 file.

Exactly. It's almost as if it's vingetted, but with sharpness (if that makes sense).

 

I will do the brick wall test. Should be able to do it tomorrow and hopefully see something. I will try at different apertures as well as different focal lengths.
