Hi.
Did solve ur problem?

Ive noticed same problem with my Eos R. Same lenses 85 1.8 usm and 50 usm plus converter Canon one. These are not L lenses .

Whats funny about this.

When I’m shooting in vertical position (trigger on top) and I’m trying get sharp face on object. Front focus on both lenses.

Now I flip camera to horizontal position everything is ok.

And another thing. I flip camera to vertical position but trigger this time on bottom. Face is sharp no front focus.

Cant understand that.

It causing problem because in vertical position trigger at bottom I can’t use grip because it’s very uncomfortable.

Anyone got similar issues?

I tested on tripod, hands about 100pic done plus 4 photo sessions. I thought it’s my fault, shaking hands. Low light etc. I went through everything.

Problem still exists.

Did you try focus bracketing to test this? The tests I see here all use a target with sloped rulers at the side which are very hard to setup with millimeter accuracy.

If you use a flat target and start a focus bracket sequence with the camera performing AF for the first frame, you should see an increase in sharpness for the first few frames if the camera is indeed front focusing.
