I'll give you two examples
One is just a scenery shot at 0 negative zoom

This is where I am at 0.75 zoom.... or 1x the - key

This is in extremis but it proves my point ( This doesn't look good though)

Now to use a situation involving A plane In this case the Kfir C7 by Eduardo Fadul
0 zoom

0.75 zoom with just a little more depth

Hope it's Useful!
