I made my third consecutive visit to Rainham Marshes RSPB this morning and wasn't disappointed. Although no real surprises in the birds being seen ,it was just nice to plod around with the camera. Talking of which I've brought a new one. This time it's a Cannon 400mm instead of a Sigma one and I'm really pleased with it. No frame fillers yet but it's alot sharper than the Sigma was.
