My wife bought me the MT 24 -EX twin flash to use with my 100mm f/2.8 L IS Macro. I took it out to have a play yesterday and found that the flash mount is 58mm whereas the is 67mm. A quick suggests that I should use a 67C Macrolite Adapter. But this is a step down as it makes the end smaller. Is this right? The MT 24-EX mount is a piece of plastic not attached to anything else so could easily be replaced with one to suit a 67mm but I don’t see anything on the website.
What are my alternatives as I really don’t want to have to try and return this nice flash.
