Actually do tell me if this is a back focus issue. I know the photo is not the greatest. This is not my concern. It seems that her right eye is in focus.
This was shot outdoors at night. The lighting comes from a lamp post. I was using my F1.8 "Nifty Fifty". It is a Sony lens. I was shooting with auto focus on. Metering mode was center weighted average. The focal length was 35mm. Using aperture Priority.
Is this a back focus issue? Or is it just how I shot it and that I have nothing to worry about?
F1,8 @ 1/80 sec. ISO 1600
Could the problem be that she was looking at you in stead of straight ahead? I would like to have a picture with another pose and compare. Could have tried posing her look straight ahead and slightly up and see if you could get that dreamy look. She should be good subject to try different poses.
I'm guessing it's the shallow DOF from shooting at f/1.8 (and probably fairly close to her).
Edit: At one point you say you used the fifty, but then you list the focal length as 35mm?

I would say it is all F1.8. And a little close to the subject. I would back up and then crop to size.

i don't have a clue what a back focus problem would look like or be - I look at the image and it seems to have "captured" what the shooter intended.......

I don't understand what you are trying to say?
Her right eye looks perfectly in focus as are her lips, we can even see the fine hair above those lips so focussing is not an issue.
My thoughts are you got what the settings were capable of producing, you have already voiced your opinion regarding the quality of the actual shot..
If you wanted more of the face in focus then obviously that was down to you and the choices you made.
May I suggest there is no issue with the camera? ;)

Yes. It is a 50mm prime. The exif data said it was at a focal length of 35mm. This is probably because it is making a comparison to a 35mm film camera.

It was just a quick candid. I wish I could get her to pose for me more often. I rarely ever see her and she is my own daughter. Lol.

I hope you are right. I just got finished looking at a bunch of other photos I took with this lens and I have not seen this proble. It must have been the circumstances.

I like the last part of what you said. Lol. But do you know what back focusing is? It is when you know that you focused on something dead on but when you look at the photo, the part you focused on is blurry but just behind your focus point, everything is in focus.

Correct but only you KNOW where you focussed and yet you are asking us if you have a focussing issue?? :shock:
So after telling us you 'think' it focussed in the wrong location, where did you intend focussing and how many times has this lens allegedly not focussed on where you intended.
Are we incorrect to assume you focussed on the eyes?
Yes I said eyes but it was your choice, not the camera's choice but your choice to have such a narrow depth of field.
One eye is sharp because I perhaps incorrectly assumed you were focussing on the eyes??
If you did not focus on that specific location, then where did you focus?
Back focus, as I understand it, pertains to zoom lenses. When you zoom in to your subject and set focus...you have set your back focus. Now, wherever you focused at the lenses max will stay in focus as you zoom out (or back) from the subject. Back focus does not occur in prime lenses.
If you focused on the right eye then, no, your camera doesn't have a problem. If you focused on the left eye, perhaps you do. Did you use auto focus or manual focus?

Yeah, that's what I thought.
