I will be as honest as I can.
In my opinion the scratch in the pics does look worse than it actually is. I have used the lense and never had any issues and I have held it too my face tonight and you cant see the mark as when on your face its too close for your eyes to focus upon it.
If your at Bricketwood this sunday then I can bring it with me and you can take a look.
Other than that its £10.00 posted mate.
Cheers
