M100 - Focus Problems

[Manda1962]

Hi.  I'm hoping someone can help.

I'm a newbie so apologise if my question seems obvious.

I've been using a 750D for a year without any issue so I have some limited understanding of camera functions.

I recently bought the M100 for use when I don't want to have the big DSLR as it can tuck in my pocket or handbag but I'm struggling badly with the AF function.

I want it on 1-Point-AF and One Shot . I lock focus by depressing the shutter and it will lock on exactly where I've put the focus and turn green, I then depress the shutter completely to take the picture.

When I download the image into Lightroom the focus can be anywhere except where I originally put it which is frustrating me a bit.

Have I missed something in the settings?

Grateful for any help/advice!

TIA

I have just managed to download a version compatible with Sierra which is the last OS before my Mojave and I now have DPP working perfectly.

And my focus points are where they should be for the M100 and the 750D so clearly had a bit of an issue with Lightroom and the focus plugin.

THANK YOU FOR ALL YOUR HELP!!!!!
