The Tiffen 67mm Digital ND Filter Kit is a complete set of filters to help you get better shots in bright light as well as assist you with some special effect images.
Neutral density filters have several uses and offer the possibility to achieve otherwise unachievable results. They enable the shooter to adjust exposure without affecting color balance. ND filters appear gray and reduce the amount of light reaching the film.
Determining which neutral density filter yields ideal results for any given lighting situation takes knowledge, experience, and a collection of such filters. Speaking generally, the 2-stop value (ND 0.6) effectively compensates average situations.
Neutral Density Filters Have Four Main Uses
To enable slow shutter speeds to be used, especially with high-speed films, to record movement in subjects such as waterfalls, clouds, or cars
To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background
To decrease the effective ISO of high-speed film (above ISO 400) and allow it to be used outdoors in bright situation
To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand, or other bright scenes that could cause overexposure
Neutral Density Factors
ND.6 (exposure adjustment = 2 stops, reduces ISO by 1/4)
ND.9 (exposure adjustment = 3 stops, reduces ISO by 1/8)
ND1.2 (exposure adjustment = 4 stops, reduces ISO by 1/16
Any vignetting on a wide angle lens tamron 35mm 1.8 on a full frame?
Asked by: Thomas
I would eat my light meter if one filter ever vignetted on a 35mm lens mounted to a full frame camera.

Will these filters cause vignetting on a 12mm Rokinon f2 lens (mirror less)?
Asked by: Sabine K.
Hi, I have used 14mm and 8mm Rokinon lenses (which are fantastic by the way) but there would be no way to attach these filters onto them because the lens curves out, and there were no threads on mine so I'll assume there's no threads on yours either. Because of the fish-eye character of the lens using a larger 4 ND glass in a holder may work for the center area but would vignette on the edges of the frame. Good luck.

Any vignetting while using aps-c censor with 16 mm lens ( 24mm on full frame)
Asked by: Swapnil S.
I use these filters with an 18mm lens and havent noticed any significant vignetting. Especially if you are correcting for your Lens profile in photoshop. The only serious draw back is at 18mm the rim of the filter is visible when I stack/screw them together to further slowdown the exposure. I have been getting by this by zooming in slightly to get the rim of the filter out of view. But when only using one filter at a time they work great.
