Contraindications
58mm Set Ordered - ND4 is 52mm!
Lens Hood for screwing, not engage. Annoying!
Quality: Miserable! Sculpture in steel casing!
CPL provides high Miserable images! Autofocus is going crazy!
ND 2 & 8 (4 I could not test as 52mm!) - Horrible!
UV - Acceptable but "just barely".
FLD - Who wants here FLD filtering, gets only purple plastic.
