A little demo of Aperture Size

This is a short post; just something cool I made while getting to know my new camera and lens.  I thought it makes a great example of the effect of varying aperture size on the photograph.

Probably all too simple for the pros out there, but for us newbies it kinda explains f quite well. Important to note is that the focus point isn’t varied at all here - the focus is manual and is fixed on the front battery (closest to the camera).  The only thing that changes is the f number.
