After work one day, I had about 3 hours to myself. I decided to kill the time shooting with a 70 mm f/2.4 using a wide open aperture.
Considering its reach, this is an amazingly small lens. With 70mm I can always use the viewfinder and there is no reason to think about shooting from the hip.
The depth of field (DOF) of f/2.4 is shallow and my only goal is to focus on the object. This is a liberating experience. The challenge is to focus on the moving target, so don’t think about what else you want to be sharp.
