[QUOTE="lucien, post: 763350, member: 36292"] OK thanks, I'll prefocus and try not to shake the camera while installing the filter. The long exposure apps are giving 4 seconds if I use a 10 stop nd filter (also known as ND100) and shutter speed of 1/250. That is pretty reasonable to me in terms of wait time. Iso doesn't have to be 100 I'll take up to 400. And I'm assuming aperture is a non factor. [/QUOTE]
