I've been thinking about upgrading to a d800 and nikkor 14-24 with the lee sw150 system. I have a few concerns about the lee system though.
I'm currently using a d7000 and nikkor 10-24, along with the lee filter system. For most of my seascape shots i'll have maybe a 0.9 gnd on the sky, and one or two nd filters from 0.6 to 1.2.
The sw150 flters are not available in a 1.2, 0.9 is the strongest. The holder also has only 2 slots, my current holder has 3. I'm not sure if its possible to add a 3rd slot to the holder and zoom the lens in a bit to avoid vignetting. I'm not sure if this would even work due to the way the filters sit out in front of the lens allowing light in from the sides.
So at the moment i can go up to 8 stops of nds if needed (also have big stopper but i can do without that), with the sw150 i would be limited to 3 stops. The d800 can do iso50 so i can get one stop back with that, and as i understand it i will be able to stop down the aperture more before diffraction kicks in due to the larger sensor. I'm not how big the difference will be with this though, currently i try not to go past f11.
I just wanted to get some opinions from d800 owners, particularly anyone that also has the 14-24 and sw150. I'm also not sure if its worth the extra money to get the d800e over the d800.
