Also, the filter scratches easy. Hand holding a Grad ND filter doesn’t work well for me because unless you hold

I am interesed in taking film images (unparalelled sharpness and gradation detail) and scanning them at higher resolution than digital images (35-40MP at around 3,000-4,000 DPI) to processing them as a high resolution digital HDR image for large format prints. it may sound like wagging the dog for what can be accomplished with the 14-24 on a D700 or D3 body and a computer, but I feel that the fine gradation created by film and the pinsharp clarity at the edges possible with film using the 14-24 will outperform anything from a full frame 12MP (or 24MP) sensor when blown up to 30"x45" as a poster. my goal is landscape art photography. I agree with handholding larger filters, it is the most sensible thing to do. On the 14-24 lense particularly the hood wont allow the filter to touch the lense, the only scratch potential then becomes between the hood flares and the filter itself. alternately you could cut a lensecap to hold a filter but because you might need to leave a lip to hold the filter in place (you could also glue it permanently to the lense cover but its a little barbaric), you wouldnt be able to use full 14mm and would have to move to 18mm or 28mm, where handholding may allow getting closer to 14mm images! I shoot underwater images with just such a lense cap and 77mm filter scenario and it works similarly but I have to zoom in a little to avoid vignetting. the whole purpose of getting the 14-24 for me would be to use at 14mm and a 4x6" filter (hand held) sounds like the most obvious option, now are there any GND 4x6 filters out there?

And if you move the hard edge up and down would that not scratch it?
