it has a set up filters i have never heard of but for the price what do u guys think? do u know the what are
(1) Multi image 3F
(3) Center Image
(4) Diffuser ?????

Aslo this other company photodiox makes star filters for about $17 each compare to the $70 tiffen filters i'm really scared of the really cheap price but they tell me that these are so easy to make and so simple thats why they are so cheap.

for the Z1 i need the72 mm correct>?
