I'm not trolling here, but why is 'increased' DoF used so often as a positive? Surely you can just reduce you aperture size (don't most lenses go up to F22?)? Is it purely because you can get away with using a lower ISO at the same shutter speeds? Or am I missing something? Perhaps someone can kindly explain this one to me.

The idea is that in bright sunlight, you sometimes have to open your lens wider in order to get a correct exposure with your camera's maximum shutter speed. Sometimes doing this makes you DOF too narrow for whatever it is you are trying to take a picture of.

In this situation, a smaller sensor is an advantage because of its larger DOF at a given aperture.

You can add also a ND filter to fix this in the larger sensor, but you don't have to with the smaller sensor.
