The Wine Country Camera Blackstone IRND Filter Kit 150mmfrom Wine Country Camera Blackstone IRND Filter Kit 150mmis 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 150 x 150mm 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 150 x 150mm Blackstone IRND 0.9 Filter is pre-installed within a Wine Country Camera 150 x 150mm Filter Vault, which is designed to encase the edges of a 150 x 150mm, 2mm thick filter for use within a separately available Wine Country Camera 150mm 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 150 x 150mm 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 150 x 150mm 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 on the other. When the lock's straight edge is aligned with the filter vault's inner edge, a 150 x 150mm, 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 150mm Filter Holder includes a dedicated inner slot for this 150 x 150mm filter vault. That slot allows a Wine Country Camera 150 x 150mm 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 the Wine Country Camera 150mm Filter Holder's outer slot that can accommodate a Wine Country Camera filter vault up to 150 x 170mm in size, an integrated safety-catch system prevents this 150 x 150mm filter vault from accidentally sliding out of the filter holder.

Q: 5. Can anyone tell me how to read/use the hyperfocal scale on this lens? I know what hyperfocal focus is and on most other lenses I know how to use it, but the scale on this lens is truly perplexing to me - specifically, why are there multiple aperture values on both the left and right sides of the centre mark? And there's also another hyperfocal marker above the distances as you approach the infinity mark. So far I've only been able to test it visually by taking the same photo at different focus values and comparing them on my computer to see which are the most in-focus. This is by no means a very technical approach to achieving the proper focus, so I'm very interested in learning how to properly use the hyperfocal scale on this lens. Thanks in advance for any information anyone can provide!

A: The aperture scales on the left and right of the focus mark indicate the approximate distances from the focal plane of the camera within which the image will be acceptable sharp at the current focus setting. It's referred to as a depth of field scale. The hyperfocal scale allows you to set your focus to the approximate hyperfocal distance for your current aperture, by aligning the f/number on the scale with the center focus mark. Irix has a good article on their site explaining DoF, hyperfocal distance and how to use both scales.

Q: 6. Can the polarizer be taken out in the filed without unscrewing the brackets?!
