wanna ask about Close Up +4 filter. to my knowledge by adding this filter it allows my lens to move closer to the subject, correct? Ibelieve it will also alter the MFD of a lens to allow us to go for a closer focus... Will it cause any distortion or image issues?? is it recommended to use especially on the 35mm or 50mm lenses? the purpose is just mainly to take pics of small objects like charms and toys at a closer range

wanna ask bro here who uses CZ 24-70 can u tell me if its normal for the lens to zoom creep when the camera is hanging, with the front of lens facing the floor?? no choice the lens will be pointing downwards cos heavier than my camera body..
