This Wine Country Camera 150mm Filter Holder Sigma 20mm Art Lensis designed for a Sigma 20mm f/1.4 DG HSM Art lens. It contains a Wine Country Camera 150mm Filter Holder as well as a Wine Country Camera 150 x 150mm Blackstone IRND 1.8 Filter, a Wine Country Camera 150 x 170mm Blackstone Soft-Edge Graduated IRND 0.6 Filter, and a circular polarizer filter. Those IRND filters can be used individually or in combination to improve the results of your photography by preventing overexposure, along with the circular polarizer which serves to prevent distracting reflections or glare.

The kit's Wine Country Camera 150mm Filter Holder allows for the convenient use of up to all three included filters. The Wine Country Camera 150 x 150mm Blackstone IRND 1.8 and 150 x 170mm Blackstone Soft-Edge Graduated IRND 0.6 filters are pre-installed within a Wine Country Camera 150 x 150mm Filter Vault and Wine Country Camera 150 x 170mm Filter Vault respectively. A Wine Country Camera filter vault encases the edges of a filter for use within the filter holder. By encasing the sides of an installed filter, these filter vaults each help to eliminate or limit stray light, which could have unwanted effects on exposure, from coming in between an installed filter, as well as the filter holder and the lens behind it. Additionally, a Wine Country Camera 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.

The Wine Country Camera 150mm Filter Holder includes a dedicated inner slot for the 150 x 150mm filter vault. That slot allows a Wine Country Camera 150 x 150mm Filter Vault within a Wine Country Camera 150mm Filter Holder to be instantly switched with an identical filter vault that may contain a different filter needed for other subjects or changing lighting conditions. An outer slot on the Wine Country Camera 150mm Filter Holder can accommodate a filter vault up to 150 x 170mm in size. The filter holder also features a quick-release button that is dedicated the outer slot. When pressed, it allows a Wine Country Camera filter vault within a Wine Country Camera 150mm Filter Holder's outer slot to be adjusted upward or downwards relative to the subject. When used with a Wine Country Camera 150mm Filter Holder's outer slot, an integrated safety-catch system prevents a 150 x 170mm Filter Vault from accidentally sliding out of the filter holder.

Installation of a compatible filter within a Wine Country Camera filter vault is accomplished by first turning the 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 compatible 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.

Use of the filter holder can be easily accomplished by first screwing the included fiberglass Sigma 20mm f/1.4 DG HSM Art lens's integrated hood. The adapter ring's screw-in locking pin allows it to remain securely attached. After being fitted onto the adapter ring, the filter holder's brass locking knob helps to provide a reliable, yet adjustable connection that allows the holder to be rotated 360°, further benefiting the use of graduated neutral density and other filters that are enhanced by varied positioning. Additionally, adapter rings are separately available for lenses with 67mm, 72mm, 77mm, 82mm, 86mm, 95mm, or 105mm front filter threads. For other lenses that have integrated hoods instead of front filter threads, including the Sigma 12-24mm f/4 DG HSM Art lens, the Sony FE 12-24mm f/4 G lens, a Phase One 28mm AF f/4.5 Aspherical or Schneider Kreuznach 28mm LS f/4.5 Aspherical lens, the Nikon AF-S NIKKOR 14-24mm f/2.8G ED lens, or a Tamron SP 15-30mm f/2.8 Di (VC or non-VC) USD or Tamron SP 15-30mm f/2.8 Di VC USD G2 lens, adapter rings which fasten over those lenses' hoods are also separately available.

That included drop-in circular polarizer filter is mounted within a geared aluminum-alloy filter ring, and is made specifically to fit between a Wine Country Camera 150mm Filter Holder and a Wine Country Camera filter holder adapter ring during use. An external knob on the filter holder integrates with the geared filter ring, allowing for the independent rotation of the circular polarizer filter in order to adjust the intensity of the polarization effect. Utilizing aluminum-alloy components for durability while remaining lightweight, the Wine Country Camera 150mm Filter Holder also features rosewood accents over its outer slots. The external polarizer filter control knob is made from rosewood as well, while the filter vaults' fiberglass construction also reduces weight while providing reliable protection for any filters placed within them.

The 150 x 150mm Blackstone IRND 1.8 Filter is a neutral density filter with a 64x filter factor that provides a 6-stop exposure reduction. Its 1.8 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 150 x 170mm Blackstone Soft-Edge Graduated IRND 0.6 Filter from Wine Country Camera is a rectangular filter that helps to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image. The filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the dense and clear areas. A neutral density filter with a soft-edged line of transition is particularly useful for images that do not have a strongly defined transition between the sky and the foreground. Neutral density filters do not affect the coloration of the image, and this filter provides up to a 2-stop reduction in light from entering the lens.

The design of these Blackstone IRND filters have 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 these filters' surfaces. The Blackstone ND Coating is also designed to help minimize any effect on a digital camera's resolution when using these filters which are constructed from Schott Ultra-White Glass for clarity as well as color fidelity and measure 2mm thick.

A Kinesis F422-X Filter Pouch is included which can fit a Wine Country Camera 150mm Filter Holder with an installed Wine Country Camera circular polarizer filter and Wine Country Camera filter holder adapter ring. Wine Country Camera filter vaults placed within this pouch are kept separated by a divider unit that creates five, nonabrasive sections and is secured using hook-and-loop fasteners. The filter vaults and their filters within those sections are kept organized through the use of among six, write-on, hook-and-loop ID tabs. Each tab can be individually moved or removed as needed, while the filter vaults and their filters are protected by a soft and nonabrasive polyester interior-lining, plus closed-cell foam padding against the pouch's front and back.

The included filter pouch is compatible with the Kinesis Attachment Tab System (KATS) for ease of use with Kinesis belts or any belt up to 2" wide, and it can also be carried using the integrated, rear hand-grab loop. Filter vaults and their filters placed within this pouch can be easily accessed by opening its hook-and-loop fastened lid. While using a camera on a tripod, the filter pouch's hand-grab loop can be used to drape the entire pouch over a tripod head. If more length is required during use with a tripod, the filter pouch's included Y208 Quick-Release Extender Strap can be connected to the hand-grab loop's quick-release buckle to provide up to 31.5" of additional length that can be used for over-the-shoulder carrying as well.

This pouch's exterior consists of 500-denier nylon for water-resistance. Two integrated D-rings along the rear side allow for spring-clip shoulder straps such as the optional Kinesis Y215 Basic Shoulder Strap or the optional Kinesis Y315 Padded Shoulder Strap to provide up to 56" or 59" respectively, of additional carrying length.
