These are excellent Linda, I too have just learned about my 50mm, it sat in the bag for months. Silly girls.
I have just ordered a set of 3 Kenko Extension Rings, waiting for delivery. Darren (dearis) is going to coach me with them if I get stuck.
It matters not, if you win or lose, it's how you play the game.
