This 1.6-stop, 100 x 150mm Combination 81EF and Hard-Edge Graduated ND Filter from LEE Filters is compatible with a LEE Filters 100mm System filter holder. This filter can be applied to create a warm cast over an entire image while darkening specific areas of that image, such as bright skies. This combination effect can be obtained under daylight when this filter is used on a film camera system with daylight film installed, or on a digital camera system with its daylight white balance setting selected. This filter's overall coloration corresponds to an ability to reduce 3850K color temperatures to 3200K, which reflects a mired shift value of +53 that can be applied to other starting color temperatures as well. While the ability to generate a warm cast extends throughout the entire filter, its neutral density feature is most pronounced at the edge and tapers to clear by the middle, with a hard-edged line of transition between the areas with and without its neutral density coloration.

This filter is non-coated and is constructed from optical-quality resin for clarity as well as color fidelity. Where its neutral density coloration is most pronounced, the LEE Filters 100 x 150mm Combination 81EF and 0.3 Hard-Edge Graduated Neutral Density Filter has a 0.5 density with a 3x filter factor that darkens the corresponding area of an image by 1.6 stops. This is due in part to the 0.2 density of the filter's overall warm cast.

The greater the color temperatures they can potentially reduce to 3200K, light balancing filters are considered to be progressively stronger in their effect when used to add warmth to a daylight image.

Q: 3. I currently have a sony A7r with a Sony FE 24-240mm f/3.5-6.3 OSS Lens. Is this filter compatible with the lens I am using? Are there any kits or adapters I need as well? Thanks!

A: Hi Christian, Yes, it will work, you'll just need a 72mm adapter for whatever filter holder you're using. My recommendation is a Lee Filter holder and a 72mm lens filter adapter. If you have a lens that takes a larger filter size, say a 77mm, then I'd get a 77mm adapter and a 77mm to 72mm step down ring. That way you don't have too many adapters. Hope this helps.mick

Q: 9. Hi, there is a little soft thing around the edges of the filter to seal the light. But there is still big gap I can see, so how it suppose to seal the light then? appreciated any comment. Thanks.

A: There are two slots that the filter can go in. Be sure to put the Lee Stopper in the slot that is the closer to the camera with the soft part towards the camera as well. Those two things should keep light from filtering in. Also, make sure that you cover the eyepiece either with tape or the cover provided by the camera mfg.

Q: 10. I want a Lee Big Stopper for my Canon EF 16-35mm f/2.8L II USM Ultra Wide Angle Zoom Lens. Which one do I need for that lens? What adapter and other equipment do I need? I also want the 3 stop and 6 stop Lee filters for this lens. Will I use the same adapter as for the Big Stopper?If not, what equipment do I need for them to use on the same lens?

A: You will need the LEE Filters Adapter Ring - 82mm - for Wide Angle Lenses. This will then attach to the LEE filter holder (which holds any 4x4 filter or 4x6 filter, such as the big stopper). The name of this kit is: LEE Filters Foundation Kit (Standard 4x4 , 4x6 Filter Holder). So, you attach the adapter ring directly to the lens (make sure not to have any UV or other circular filters attached or it will vignette), and then the filter kit attaches to that. You then slide in any LEE or other 4x4 filter you want.
