F-Stop - Sharpness

While it is common to shoot copy work using a small aperture in order to achieve maximum depth of field, I recently ran some tests shooting at f20 and and f8 and here is what I found.

f 20 on the left, f 8 on the right

These images have not been sharpened in Photoshop. They were both shot with the Canon Eos 1ds Mark III using the EF50mm/f2.5Macro lens. It is clear that the f8 image is significantly more clear than the f20. Not surprising news, I know, but it's fun to shoot tests to confirm.

Here are larger images for your enjoyment.
