Just back from the park! In the end I took the X-T1 with the 14mm and 55-200mm and the GoPro. Haven't had a chance to pull the pics from the X-T1 yet but did throw together a time lapse from the GoPro. This was taken over the 2 hours before sunset as we were out fishing on the glass lake (watch the canoes zipping around), stick around for the end as the skies get much better :-)
Pics will follow in a day or so, good time had by all!
