Singh-Ray 77mm (Thin Mount) Vari-ND Variable Neutral Density Filter
Key Features
  • Controls Up to 8 Stops of Light
  • Good for Blurring Motion
  • Holds Optical Quality at All Settings
  • Fast and Easy to Use
The Singh-Ray 77mm (Thin Mount) Vari-ND Variable Neutral Density Filter - This neutral density filter gives you the capability to use fast film in bright sunlight. ND 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 reduce the amount of light reaching the film.

When used with a digital camera, you can effectively see how this filter works. After the initial exposure, you can check your LCD image and then make whatever change in exposure you feel you need to enhance your image. By rotating the ring, you can either increase or decrease the ND effect. This will be especially useful when trying to achieve "blurred" or "panned" shots.

The filter contains "index" points to help you mark your spot. They do not represent actual ND settings , i.e. non-calibrated - but are there to help you re-set your filter when you wish to recreate the effect.

Singh-Ray RT-86 Overview

The Singh-Ray 77mm (Thin Mount) Vari-ND Variable Neutral Density Filter - This neutral density filter gives you the capability to use fast film in bright sunlight.

Note:
Singh-Ray cannot predict when vignetting may occur - especially with very wide angle lenses. To avoid vignetting, adjust your focal length, position, and/or composition to remove the vignetting - use your digital camera's display for reference.
Front ring can accept a Mor-Slo 5-stop Solid ND Filter or a Cokin holder for ND Grad Filters
Note:
To stack Mor-Slo with Vari-ND, at least one filter has to be standard mount with front threads - two thin-mount filters will not stack
Front Min/Max density ring lets you adjust density from 2-2/3 to 8 f/stops

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 which could cause overexposure

Neutral Density Factors

ND.3 (exposure adjustment = 1 stop)
ND.6 (exposure adjustment = 2 stops)
ND.9 (exposure adjustment = 3 stops)

Why do you only carry the filter in the 77mm size?

Singh-Ray manufactures the Vari ND in nine sizes - from 49mm to 82mm - so you may want to look around or visit Singh-Ray's site.

question

Can you use the Nikon hood when this filter is attached to a 24-120 zoom or 24mm prime?
Asked by: George G.
No, not at the 24mm setting . It will cause some vignetting. Only a little though, so you could shoot wide and crop out.

question

If I use a polarizer with this filter, where do I place the neutral density, in front or behind the polarizing filter or will it work both ways ? The answer will help me choose between a thin or regular mount filter. Thanks.
Asked by: Michel F.
My opinion is I would put the NDExposure filter on first. The polarizer on the outside because you will need to rotate to the desired position. The downside is you will need to set the polarizer, focus then set the nd number.

question

Will this filter vignette on the Nikon 16-35/f4 lens?
Asked by: George T.
The filter comes in an 82mm width as well and you could always mount at 77-82 step-up ring if vignettes are a worry because you shoot at 16mm A LOT.
