EOS M50 out of focus

[NickSlav]

here wo go again (((((( I have an issue with my m50. i made a studio shoot with sigma 18-35 with original canon adapter (manual mode iso100 1/200 f2.5) with narural light, and i noticed that raws miss detalization and they are back focused (((( Leens have been tested on many bodies and it works fine. Canon DPP show focus point on face. What is the problem can be? Why only on my m50 this lens have  strong back focus ?

What AF settings are you using on the camera, and are you recomposing?

I downloaded your larger image and it has been edited, so I cannot read the detailed camera settings using Canon DPP software. Here's an example of the detailed settings I can see for an EOS M50 Mk2 JPG image straight from the camera.

This is what I see from your image.

If you can give us a screenshot like this from your image then it makes it easier to help you.

So io can give screen shot but ur dont understand bacause it on my native language and i dont know how to make it english. but a can tell the what is the af settings (AF.mode one shot, Face detecting + Tracking AF, continuous AF - enabled)

Brian,

Before offering my "non-expert opinion, I'd like to get your opinion on what I think may be the issue and a possible solution for the orginal poster.

I'm guessing that the face of the model is not in sharp focus (but the background is) because teh AF area select mode is "Face detection + Tracking AF" per the EXIF data.  

Again, my guess  is the the "Tracking AF" was hunting and focused on the background instead of the face and eyes.

My camera doesn't have face detection, but in order to get the model's face in focus, I would have chosen the Center focus point (I have a T7 with 9 focus points) One Shot AF, focused on the models left eye and upon hearing the beep, taken the shot.  

What do you think?

Here are the full details for the RAW Image, as shot:

Thanks for the RAW file NickSlav, and to zakslm and Trevor for the decoded info.

I don't see anything in the EXIF that would point to a camera settings error. I have two thoughts;

1. Maybe the camera and lens don't work together well. Even though the lens works well on other bodies, maybe there is some body specific issue with this combination. 
2. With the camera set for one-shot AF and the AF area set to Face detection + Tracking AF it is possible that the model or camera moved after the AF locked, but usually I'd expect to see much less of a focus difference. 
3. Turn off preview AF, it might be called continuous AF in the camera menu. 

I'd advise the following steps. First check the camera with other lenses - particularly Canon lenses if possible. Does it work consistently and achieve focus. If so this could indicate the lens is the problem in this combination of camera and lens. Secondly I would try to use servo AF not one shot. With the camera set for face detection + tracking AF, servo AF will keep focussing right up until the shutter releases, and will also move the AF point to keep it on the face even if you recompose the frame. I've found that this gives me consistently focused results with mirrorless cameras.

Face detection + tracking AF is the name used for the whole frame being the AF area. It's a little like using your T7 with all AF points, but the M50 has AF points all over the frame and has intelligence to identify and prioritise faces. The EOS M50 also has 1-point AF like your Rebel T7, but where you can put the AF point at one of 9 places, the EOS M50 can put it in up to 143 different positions depending on the lens used.

One of the biggest changes in my own way of working when I went from DSLR to mirrorless was to switch away from the old way of "put the AF point on the subject, focus, then recompose". I now let the camera put the focus point on the subject, trusting it to get it right almost all the time, and me to compose as my priority. This has lead me to compose my shots better as I can devote my brain to composition and let the camera deal with AF.
