Had a wonderful afternoon on Saturday at Gigrin Farm. Booked the Big Tower Hide - well worth £20. Took over 800 images - about 80 usable images and 5 wow images. Here is one of them:
Taken with my Canon 400mm f5.6 lens - very good for birds in flight though I did get some great images with the 500 as well. ISO 1000 f8 @ 1/1250sec.
