Yesterday there was a bomb threat in Derby and I had my Canon G9 with me. This one was taken with the lens set at Hyperfocal distance set in C2 (custom control) which means it is instantly available to me.
The benefit of this is it means that the lens does not have to auto focus which allows for almost instant shooting. Setting the lens to Hyperfocal distance equates to everything being from about 4 feet to infinity will appear to be sharp, depending on what aperture you use.
This is obviously very useful for street photography, parties, or any other quick focus applications
