Cokin Filter Series Guides

Hits: 399

Many have asked about Cokin filters, how to use it…which one should I buy…what are the needed items…etc.

Here I have decided to write a short blog on Cokin filters. Some of the info are obtained from Cokin websites.

The Types

From small to big: Cokin A Series, P Series, Z Series and the latest X-Pro Series.

A Series – 36mm to 62mm

Recommended for lenses between 36 and 62mm in diameter with a focal length over 35mm. Cokin square filters fit into a holder and are attached to a lens via an adapter ring, the photographer has a number of immediate advantages:

a) there is no need to duplicate filters to fit different size lenses,
b) up to three filters can be used at once to create unique effects,
c) the photographer has control over the positioning of the effect on the photograph.

How the Cokin System works

1. Screw the adapter ring onto your lens. System “A” rings come in the following diameters; 36/37/39/40.5/41/42/43/43.5/44/46/48/49/52/54/55/58/62mm and Hasselblad special rings.
2. Slide the filter holder on the adapter ring until it snaps in place. The filter holder is now solidly attached to the lens, yet it can rotate both left and right.
3. Slide the filter into one of the filter holder slots. The one closest to the filter holder housing is the narrowest; it allows the use of round filters with notched edges (polarizer, star filters..). The two central slots are intended for square filters. The outer slot can be used either for an additional filter or for a coupling ring.

Most popular filters – There are over 140 filters to choose from in the range.
The most popular are:

1. Polarizers – Designed to eliminate unwanted reflections and darken skies.
2. Graduated – Add colour to a scene by using a Cokin graduated filter to enhance a dull sky, or use a Sunset filter to add warmth.
3. Pastels and Diffusers – Ideal for portraits, still life and landscapes, to create a moody atmosphere and a softer effect.
4. Warm-up Filters – Add warmth to a portrait shot, giving improved skin tones.
5. Colour Filters – Colour correction filters are available, as are Neutral Density filters and filters specifically designed for use with black and white film.
6. Optical effects – There is a wide range of filters available to add special effects to photographs, such as Starbursts, Multi-image, close-up, Rainbow, Double exposure etc.

What You Need?

First thing you need to do is to select the suitable series to your needs. Take note that filter from different series are not interchangeable. You can use P filter on A holder nor vice versa.

Cokin Filter System consists of the 3 most basic items: Filter + Filter Holder + Adapter Ring. Additional accessories are like Hood (to shade sunlight and reduce reflection or ghost), filter holder (can hold few pieces of filters in a holder), etc.
