Subject Distance 0.6 Caption You can see the high thread count inside the T ring throat for the adapter to 1/25" that I've removed. There also appears to be one or two threads right behind the mounting holes that should be the advertised 2" filter mounting threads. I'm not sure about how easy it would be to insteall or remove a filter there though! And what's with all the white specks?!!
