My cameras (Fuji X-T30MKll and Nikon D7500) have so many features.  They have menus that have tons of different options, and I couldn't tell you what most of them do.  Nor, do I care about all those functions. 

I just need to know how to point my camera into the proper composition of a subject, focus, set my f/stop for depth of field, and set my shutter speed for the proper exposure.  I also need to know about setting my ISO and white balance, as I shoot jpegs, that's it.  

So, that's all I really need to know, so I have never explored all the other options in my camera's menu.  

I'm not any better with my camera than anyone reading this post.  You are all as experienced as me at these simple functions.

What I excel at is not my camera tech skills, but my ability to find good subjects to shoot, compose them well, and to apply good post processing skills to each image.

To many photographers spend too much time on the camera skills, and less on knowing what is a good subject to photograph, understanding composition, and practicing post processing.

I've always said that once I find a great subject to shoot, the easy part is photographing it with the camera.
