Hello
I was told that it is necessary to unscrew the three VERY SMALL screws in the ring near the back side of the lens; I had a similar problem to yours, haze/fog inside the lens, and I wanted to solve it, but I was not able to disassemble the lens due to my inability to remove those screws
Later I asked a professional opinion and I was told that some inner elements are glued together, I could cause damage in my attempts to separate them ...
My final option was to sell the lens, warning the buyer about the problem🙁
I hope you suceed, I look forward to know what happened.
Good luck
Joao
PS. I am not so enthusiastic about those add-on lenses, pictures seem less sharp. OTOH I agree that the camera looks great with those lenses on.
