Morning Robert, the Raynox will fit straight on but I found it a bit tight and I know that somebody, I think on here, broke one of the squeeze clips doing so. If you are going to do it then attach the adapter first then screw in the lens after.
I bought a cheap filter adapter from Amazon, which took about 10 days to be delivered from lord knows where, but can stay on the camera lens at all times and the Raynox can clip on quickly as and when required. I have found that with the camera's lens cap tied to the camera strap I can hang the Raynox on the lens cap when I am not using it on and clip it on when I want to use it - just remember when you take it off quickly to shoot without Raynox that you need to clip the lens cap to it. I nearly lost mine when I simply let go of it ... oops
