The newer camera’s all have a fine tuning for lens focus. It can happen that your lens has to much front or back focus. This means if you focus on a object and the details of your focus are not on the spot you did focus on but on a point before that, it is called front focus. The other way around is called back-focus where your lens is more sharp behind the focus point of your subject.
All this can be corrected if you have one of the camera’s mentioned on the list on the bottom of this post. If your camera is not on the list you can still measure it and pay attention to where you focus.
To figure out how your lens is focusing you can use some DIY solutions or a system that is ready to go. I’m in the middle of getting the lensalign pictured here.
We will use that in our meetup-group to calibrate lenses from different brand. I will post an update with the experience.
The following camera’s can be adjusted;
