Kase K100 K9 filter holder set incl. CPL polarising filter for rectangular filters

SLIM filters (1.1mm material thickness).
The current version of the K9 filter holder uses combined filter rails that can accommodate both standard 2.0mm rectangular filters and 1.1mm slim rectangular filters.
Please note: If you mount slim and normal rectangular filters at the same time, you must mount the slim filter first - in the first rail - counting from the lens end / filter holder.
The K9 filter holder set is an excellent basic equipment of a photographer and offers everything to start directly with filter photography.
The K9 filter holder set by Kase convinces with:

its large scope of delivery
its ease of use and
its excellent value for money.

Polarising filter
As a special feature, the filter holder has a newly developed round 90mm polarisation filter that is attached to the base insert of the K9 filter holder via magnetism and no longer needs to be screwed into the adapter ring. This makes it possible to attach and remove the polarising filter quickly.
In addition, the polarising filter can be easily and continuously adjusted by means of a turning wheel on the filter holder without having to turn the filter holder itself. Even when wearing gloves in cold weather, you can easily adjust your setup to the current conditions.
The CPL filter integrated in the set has a nano-coating so that your polarising filter is spared from streaks and can be cleaned quickly and easily.
The CPL, which is indispensable in photography, is included in the scope of delivery, so that no further purchase costs are necessary for you.
The polarising filter can also be used independently of the actual filter holder.
With this, the magnetic polarising filter simply has to be inserted into the basic adapter ring.
Since two of these basic adapter rings are included in the set, you can work with two lenses at the same time.
Processing
Unwanted light reflections are minimised by installing it directly on the lens. The polarising filter can be adjusted to the desired position with an adjustment wheel on the filter holder, even if, for example, an ND or GND filter is used in the holder.
The Kase K9 filter holder system is precision CNC machined from aluminium and anodised matt black to minimise light reflections. The filter holder is designed to prevent stray light from entering from the side. In addition, the K9 filter holder stands out due to its lightness and flat design and can convince with its stable, durable workmanship.
A total of 4 adapter rings for common lens sizes are included in the set.
The two basic adapter rings are magnetic on the outside.
On the inside, each basic adapter ring fits lenses with either 77mm or 82mm lens diameter.
The outer diameter of the base adapter ring is 90mm.
If your lens has a smaller filter diameter, additional screw-in Step Up adapter rings may be required.
Two of these adapter rings, with a size of 67-82mm and 72-82mm are already included in the delivery.
Filter inserts
Two filter inserts are factory fitted and a third can be retrofitted if required. The third filter insert is included in the scope of delivery.
This provides up to 3 filter inserts.
