The Wine Country Camera 100mm Master 5-Filter Kit 77mm Adapterfrom Wine Country Camera 100mm Master 5-Filter Kit 77mm Adapteris an ND filter with an 8x filter factor that provides a 3-stop exposure reduction. Its 0.9 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing exposure time or increasing aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

The design of this filter has been optimized for use with digital sensors and to promote nearly flat attenuation of visible and infrared light. Due to imaging sensors' greater susceptibility to infrared light compared to traditional film, color casts can occur when photographing darker subjects that require increased exposure times. To provide neutrality across the visible and infrared spectrums in order to eliminate color casts and ensure cleaner, truer blacks, one layer of Blackstone ND Coating is applied to each of this filter's surfaces. The Blackstone ND Coating is also designed to help minimize any effect on a digital camera's resolution when using this filter.

This Wine Country Camera 100 x 100mm Blackstone IRND 0.9 Filter is constructed from Schott Ultra White Glass for clarity as well as color fidelity, and measures 2mm thick.

The Wine Country Camera 100 x 100mm Blackstone IRND 0.9 Filter is pre-installed within a Wine Country Camera 100mm Master 5-Filter Kit 77mm Adapterwhich is designed to encase the edges of a 100 x 100mm, 2mm-thick filter for use within a separately available Wine Country Camera 100mm Filter Holder. By encasing the sides of an installed filter, this filter vault helps to eliminate stray light, which could have unwanted effects on exposure. Additionally, the Wine Country Camera 100 x 100mm Filter Vault reinforces an installed filter's rigidity while preventing its sides from having to come into direct contact with a filter holder's slots. This protects those side surfaces and promotes sharp results by ensuring that the filter remains flat.

Installation of a compatible filter is accomplished by first turning the Wine Country Camera 100 x 100mm Filter Vault's brass Wine Coin lock into the open position. Located along the front of the filter vault's inner and outer top edges, the Wine Coin is a flat, disk cam lock that features a straight edge on one side and a rounded edge at the other. When the lock's straight edge is aligned with the filter vault's inner edge, a 100 x 100mm, 2mm-thick filter can be set within the front of the filter vault. The Wine Coin can then be turned so that its rounded edge obstructs the installed filter, securing it within the filter vault.

A separately available Wine Country Camera 100mm Filter Holder includes a dedicated inner slot for this 100 x 100mm filter vault which also features a quick-access side handle. The combination of that slot and the side handle allows a Wine Country Camera 100 x 100mm Filter Vault to be instantly switched with an identical filter vault that may contain a different filter needed for other subjects or changing lighting conditions. If used with any one of the Wine Country Camera 100mm Filter Holder's two outer slots that can each accommodate a Wine Country Camera filter vault up to 100 x 150mm in size, an integrated safety-catch system prevents this 100 x 100mm filter vault from accidentally sliding out of the filter holder.

A: I have no direct experience but have been doing some research. If you look at the Wine Country Camera website FAQs http://www.winecountry.camera/faqs/, there is this statement, so I presume that the holder generally works for Lee filters: Service Advisory: We are noticing that some Lee grads have been produced at a thickness outside of their specification.
