Macro Sharpness Test: This test was taken to demonstrate the effects of aperture on DOF and sharpness. The test subject was a Spotted Flower Chafer, chosen due to the fine detail in it's hair and body as well as being relatively "deep" providing a good test for DOF and sharpness. The test was taken with a 20D on a tripod using a remote release (TC-80N), the beetle was still alive (as variations in leg position show) but turned on his back to limit movement. Each frame was shot at 1/320s ISO 400, exposure was adjusted for using a MT-24EX flash ring. Apart from increasing exposure on each frame by +0.67 in raw conversion and removing dust spots, no editing (including noise reduction/sharpening) was done.

This frame shows a 100% detail crop from the beetle at f/11
