Sorry every body I am at the head of the list and it's due to eye cups.
Andy - these will get a 20 in any comp - so don't turn up with these OK or you're walking home mate - seriously good shots
Very, very nice. Many a time I run across a shot like that, but the background is horrible, so it doesn't come out nicely. I once got a shot of a kingfisher diving into a pond, but because of the terrible background, it's not a good shot at all.
