The Fuji X100S isn't a camera I'd recommend for macro photography. Although the 35mm equivalent lens focuses down to 10cm, both the camera and the subject need to be very still for the auto-focus to work at this distance. So I keep it for more general shots.
However, when this red admiral butterfly landed close by, I thought I'd give it a go. Amazingly the butterfly stayed really still, and there wasn't too much breeze. I was able to reach forward across the vegetation to get to the minimum focussing distance. Only two of the dozen or so shots I took were reasonably sharp. Holding the camera upside-down allowed the flash to illuminate the underside of the wings to bring out a bit of colour. Apart from cropping about 20% off around the edges, this is the photo straight from the camera.
