I was just looking for a 67mm GND filter at Adorama and the only one I see is a Sunpak. I don't know anything about this brand. Has anyone heard of them or used them? I'm hesitant to buy it since I know nothing about this brand,
Also it's a bit to cheap to be real.
B+W, Heliopan and Tiffen have 67mm grad ND filters. Have a look.
That said I really recommend against round screw-in GND filters. The graduation is always dead center at the "equator," and that's rarely where you want it for optimum image composition. A rectangular filter lets you adjust where the graduation falls in either vertical or horizontal compositions for optimum placement. You can buy a Tiffen GND in Cokin P size plus a Cokin filter holder and Cokin 67mm P-adapter ring and have a much more versatile rig.
That's true Henry and I have thought about that in the past, but I get into some rough terrain on occasion and have stuck with the screen in basically for the convenience. I've found I can put the graduation where I need it in post.
I had checked your site and saw that you ha those brands but to be honest I've stuck pretty much with Adorama the last few years for a number of reasons.
