I have just purchased a Minolta D-90 with two lenses - a Nikon 55 - 200 mm
F/4-5.6G ED AF-S VR DX zoom and a Sigma 18-50mm F/3.5-5.6 DC HSM with motor. I
have a large collection of Cokin filters that I had used in the past with a
Minolta SLR. This was an "A" system. It appears that the only change I will
need to make to use this system with my new Minolta is the purchase of a 52mm
adapter ring. However, I am concerned with the possibility of viginetting with
the "A" system. Will the graduated filters I have fit in the "P" or other
holders? Will this system work with my zoom lenses? Any and all suggestions or
helpful hints will be appreciated. John
