Success!

I popped in to check the terns on Derek's tonight and was delighted to find two of these dudes on the pit - Black Terns.  Until today I'd struggled to get flight shots with my GX7, but a spark last night meant that I decided to ignore the EVF and use a magnified viewer over my screen instead.  It seemed to do the trick - several decent keepers amongst the few hundred shots I took - a better rate than simply using the EVF.
