Product Description

The PS-Technik Rehoused Cooke Speed Panchro set is an amazing little set of lenses. 

However, they in practice, they do present some problems to film productions. Their small size means that using a mattebox, especially a clip-on, can be a recurring difficulty with almost every lens change. With their small front area of the housing, clip-on matteboxes are almost impossible. Also, because of this small front area, donuts often press against the focus ring adding friction on every focus pull. Additionally, the 18mm is prone to vingetting as it is so deeply recessed into the camera body. 

This donut solves all of these problems presented by this lens set.

1) No fiction on the focus ring. It has purpose build lips to perfectly set the depth of the donut and keep it from pressing on the focus ring.

2) Added stabilty. The center point of contact is shifted deeper into the donut than a normal donut on these lenses. This moves the center of pressure onto the barrel of the lens. This, in combination of the lips adding additional points of contact, means that the mattebox is significantly more stable with this donut.

3) No more Vingetting. Unlike regular donuts, this one is not the same all the way around. It's designed with special cut outs on the sides of the frame to allow the full field of view of the 18mm to pass through. With an MMB-2 there is no vingetting what-so-ever.

For PS-Technik Cooke Panchro Owners, this is a must have.
