Focussing Pana 20mm at infinity

I wish to take photos of a parade. It will be held in twilight to semi darkness. Using the GX7 and 20mm 1.7, if I focus at say 200 yards and then lock focus only using the AF/AE button can I get sharp near to far pics with an aperture of 1.7 or do I have to increase aperture? Obviously 1.7 would be more desirable bearing in mind the lighting situation.

Regards.

Jonantony.
