Wide Not Deep
It's more common for an inheritance tree to be wide than deep.
In your application code, you likely won't see a Camera class inherit from a chain of 13 classes up to Equipment. If you do: run. There are better organizations to work for, I swear.
Why Wide Not Deep?
A child class must fit every parent class "type" above it. That just doesn't happen very often in a deep tree. It's more likely that you'll have a base class with many child classes that are slightly different variations of the base. They're all "siblings" of each other.
