Wine Country Camera 150mm Master Filter & Holder Kit with 77mm Threaded Adapter Ring

About 150mm
150mm filters are large filters designed specifically for large-barrel wide-angle lenses which would otherwise be unable to accept filters such as the Nikon 14-24, the Schneider 35LS and the Sony 12-24.

The Filter Holder System
The base of all of our kits is the WCC Filter Holder System. This system is the absolute reference for quality in filter holder systems. Here are some of the features:

• The ability to install or remove the ND filter without disturbing critical focus or composition
• Push button adjustable grads that allow precise and easy adjustment.
• The most user friendly polarizing solution ever devised for a filter holder system.
• Filters that can be adjusted independently of one another without interfering with each other.
• Wood contact points that remain warm on the coldest days and cool on the hottest days.

WCC Blackstone ND & ND Grad Filters
Our Blackstone ND Filters are the technological cutting edge in filter design. The Master Kit contains the two most essential filters for landscape photography. The 6 stops ND is the perfect medium density filter, giving you the creative possibilities of misty waterfalls, ethereal streams, and heavenly clouds. The 2 stop ND grad works in nearly every outdoor situation. It's the one grad you'll pick when you need a grad.

140mm Circular Polarizer
The Wine Country Camera holder system features an integrated rotating, circular polarizer. The polarizer fits inside the holder body, eliminating reflections and allowing geared rotation. We worked with a high-end optics manufacturer to develop the highest possible quality polarizer. Our polarizer uses 2.5mm thick Schott optical glass that is fire polished, free of surface aberrations and suitable for use with the highest resolving cameras on the market - including 150+ megapixel medium format cameras. Note: The majority of the cost associated with the 150 system is due to this high quality polarizer.

The Adapter Rings
Our adapter rings are unlike anything that has ever been made before. We design the adapter rings to be manufactured on a special type of 3D Printer called a Multi Jet Fusion. Because they're printed, we aren't constrained by the limitations of molding. The result is that we can build a complex structure inside of a complex structure (think ship in a bottle). In the case of our adapter rings, we can build a clasping mechanism on the inside of the adapter and a light tight hood on the outside of the adapter. These designs are impossible to manufacture by any method other than 3D printing. The fusion jet process creates glass filled nylon parts with zero void, and an extremely high strength to weight ratio. The adapter rings are produced with the absolute cutting edge in manufacturing technology, and are made in San Diego, California. The adapter rings are custom designed for each lens.
