Remember that ISO 50 on Nikon cameras such as the D800 and D4 is not actually ISO 50 (look at DxOmark's ISO charts for the camera) it is just ISO 100 underexposed by one stop in the camera. I don't think you really want them to give you ISO 4 or even ISO 25 by that method. That being said you don't need a 10 stop ND filter to get down to the equivalent of ISO 4, you need a 4 2/3 stop ND filter.

I'm not 'stuck' in the 'good old film era'. It's sheer practicality based on experience. I grew up shooting ASA 25 all day (and night!) long. ASA 400 was crap right of the box, but the best there was if you wanted to shoot fast action light sports in low light. Sure, you could 'push-process' it in the darkroom to 800 or even 1600, but that just made the images even crappier.

What's so insane about wanting to shoot with a lens at the sweet spot (f/8 or f/11), and have a 30-second shutter time in broad daylight without having to plop down $500 for a special filter to do so?
