Hi Oli glad to hear you are getting on well with your HS30. Loved looking through your flickr gallery, some lovely captures there and lots of variety , Norfolk is known for its excellent light qualities and superb variety of bird species as is Cornwall .
I am still at the bottom of a steep learning curve regarding manual camera settings , i attended a surprisingly good day-long basic digital camera course last month but I regret I didn't plumb for the intermediate course now.
I have found numerous online tutorials including the superb free Karl Taylor video courses and the concensus of opinion seems to be to use A Aperture priority mode for birding rather than S Shutter priority.

Why do you feel shutter priority mode is better for bird photography ?
