No need to stop down.

At 7mm you always have substantial DoF. But to maximize its use it's important to focus such that everything you want to have within acceptable focus is within that DoF. This often means focusing a bit off-center to something that is closer than what is in the center.

Below is an example of an image where the extreme wide angle at 7mm was needed (despite it distorting people near the edges). And the difficult lighting asked for f/2.8. For me the sharpness throughout the frame is acceptable. (This image was later used by a newspaper, with permission.)

7mm f/2.8

The image below was taken at f/4 and I don't see improvement in bringing more into acceptable focus. The circumstances of both the image above and below are not likely to lead to great images, but as a memory of the events they are good enough for me.

7mm f/4

Enjoying the Olympus OM-D E-M5.
