Diane K. Costello Photography

I borrowed a 300mm f/4 lens from a friend of mine for an upcoming whale watching trip out of Half Moon Bay.  I don't typically shoot with anything more than a 70-200mm, so I thought this would be fun.  We took Gromit out into the field behind the house so I could "practice"...funny I kept trying to zoom the lens.  I had a great time.  This particular lens is really fast and was able to focus on Gromit running toward me.  Canon 7D, 300mm f/4, 1/1000 @ f/4.

Love, love, love that running happy face.
