Thanks everyone for all of your replies. I went with the B+W 77 cpl and got their step up ring. The widest lens I have is the Tamron 17-50 and I think it will work fine on that and the 70-200 F4 IS that I have. I was going to do an engagement shoot Friday and going to give it a try for some of the sunset pictures. They are family so don't really care about me experimenting.


Thanks again,


Jayson
