Need a ring mount for 100mm canon lens for a macro light

[omar]

I bought an led macro ring light for my canon 60d + 100mm macro lens

It's come with two ring adapters 72 and 58mm
Neither of these fit

Where can I get an adapter that will hold the light in place?
What size do I need to get?

I looked up adapters on ebay and they costed £20 - similar price to what I actually paid for the whole light!

I would add that I purchased after seeing videos on YouTube , so didn't just buy out of the blue

Thanks

I presume you have a 67mm thread on yours??

A set of step up / down rings should be cheap, I keep a full set of photodiox step up and step down rings. They come in very handy when I need to adapt something. You can use just one or stack several to get to the size you need. It just takes one to go from 67-72mm.

Just be sure to get a filter wrench.
