Give water and sky minutes to transform. ND 100000× Golden Series (GS) combines very strong light reduction with quality optical glass and traditional screw-in mounting. Choose 72, 77 or 82 mm to match your lens.
ND 100000× corresponds to approximately 16.6 stops of reduction and about 0.001% light transmission. At the same aperture and ISO, exposure time increases approximately 100000-fold: from 1/250 s to 400 seconds (6 minutes 40 seconds), or from 1/125 s to 800 seconds (13 minutes 20 seconds). These times are approximate; light can change during the exposure. Compared with ND 32000×, exposure time is approximately 3.1 times longer.
The checked 82 mm ND 100000× GS has 14 anti-reflective layers (7+7), protective nano coatings and a brass frame. It has a front thread and supports a standard lens cap. Anti-reflective treatment reduces glass reflections, while nano coatings make cleaning easier. Check each product for other sizes.
Match the thread diameter marked Ø on your lens. Explore the 72 mm ND 100000× GS, 77 mm or 82 mm. Screw the filter into a matching thread or suitable step-up ring. When stacking filters, check the front thread, vignetting and lens hood clearance.
Before fitting the filter, set composition, focus and meter the base exposure. Use a sturdy tripod, remote release or intervalometer and, depending on your camera, Bulb or a timed long-exposure mode. Allow for changing light and the growing importance of noise during very long exposures. With a DSLR, prevent light entering the optical viewfinder as instructed by its manufacturer. Strong ND filters may introduce a colour shift; the filter, lighting and white balance affect the result. Shoot RAW for greater room to refine colours and maintain consistent conditions for comparisons.
