An even better strategy would be to read the owner's manual of any camera you are considering before buying it and figuring out if it will work for you.
Yes and yes. My GR III has 5 categories and over 100 settings. After spending 10 minutes reading the manual and 30 minutes of fiddling with the camera I was set. Would only need to turn the USER dial between its three slots in real use. After my first major excursion (to Cuba) I refined the custom functions assigned to these slots. The bond is formed.
Read the manual. Read the manual. Read the manual.
Do not shy away from it. Do not blame your tool for being able to do more things than you're capable to utilize. Nothing wrong with knowing its full capacity. Sometimes it changes you for the better as well.
A paint brush does not come with a manual but would take a lifetime to master. A painter also knows how different pigments present in his paints handle differently under various conditions. The only way to go is constant study and research and endless trial and error. We're gifted with today's cameras that come with clear directions printed on paper.
