Does anyone have any idea where I can get those attachment lenses from as I bought one that didn't come with the extra lenses. Is there a standard for 27mm filter lenses. I've tried to google them but all I get is lenses with 27mm field of view instead of thread size. They are called Eumiconar and Eumacronar.
The only ones i found for 27mm were uv filters on Amazon. But you could use step up rings. I saw some even for 27mm. Or u use a mattebox with filters. I hope that answered your question
