...for dummies, such as myself, that tells how things like the zebra stripes work or how to use them effectively when using the A7ii? I'm the type that can work things if I know a little bit about the 'how' something works. Take the focus on my D7000. I couldn't get it to take a decent, in focus shot until I learned how the focus points actually worked, then it was not a problem. Any suggestions for the A7ii?
