Hi everyone, I was wondering if I can get some advices before I make a purchase on a graduated ND system. This will be for my 24-70 f/2.8 lens + Canon 5D MKII. I've never used a GND filter before, so I do not know if I am buying the correct items, or knowing what is a good brand to buy. Please let me know of these items are what I would need to purchase (I've gone with Lee because I've heard good things about this brand for its price):
Resin 4"x6" filter
Lee filter holder
77mm Adapter. This is where I get confused. I see listings on B&H for two 77mm adapters. One is $27.95, while the other is $59.95. What's the difference?
Also, is it necessary to purchase a filter holder and adapter? I've heard stories of photographers just manually holding their GND filters in front of their lens as they shoot. Is this practical and does it really work?
Cheers, and thanks in advance for any info.
