These are part of a First World War re-enactment group. You can see they are a medical division by the Red Cross on the woman’s shoulder patch and on the haversack of the woman to the left of the frame.
This was my first outing with the little camera, and it takes some getting used to, but when it gets it right it is sharp. And this is a crop of about 30% of the full frame.
