Hi fellow members,
I am new to Graduated neutral filter (GND) and I just bought a Cokin P-series filter system (second hand).
My gear: 18-200mm Nikkor VR II lens + 72-77mm setup ring + 77mm adapter ring + Cokin P-series filter holder + Tianya GND filter (sounds quite a heavy installation huh)
When I shot at 18mm, I noticed there is vignetting at four corners of the images.
Is is a normal phenomenon? Anybody who using the similar setting has ever spot this phenomenon before?
If I just change card holder to Z-Pro series, will the vignetting gone at 18mm?
Thank you for any advice.
