If you contest the fine and it goes to a magistrate, you will almost certainly lose. That junction is in City of London, just over the line from Islington. It may be worth trying a pleading letter to City of London Police, saying that you are willing to go to them and discuss what happened and how you always obey the traffic law. My guess is that you have about a 10% chance.
Otherwise just pay the fine and think of the times you haven't been caught.
