The River Misbourne at Great Missenden that has been dry for several years. Here it flows into a banked fishpond once used by the monks at Missenden Abbey. An Augustinian monastery founded in 1133. It was ruined in the Dissolution of the Monasteries and the ruins later incorporated into a Georgian mansion. HS2 is due to run just beyond the ridge of trees on the hill. I got the much criticised 16mm NEX pancake, split from kit, cheaply from Amazon, I can't find much wrong with it at my favourite f8, also pretty good with the 12mm UWA convertor except in the extreme corners.
