A UNIQUE POLARIZING FILTER

THE Z-PRO IS THE LOGICAL CHOICE

Set in a patented notched ring, the polarizing Z-PRO ﬁlter ﬁts into the ﬁrst slot,

independent of the rotation of the ﬁlter-holder. It is used without any special mount

or additional accessory and can be combined, if necessary, with a graduated ﬁlter: you

begin by adjusting the graduated ﬁlter (rotation and height), then proceed by rotating the

polarizing ﬁlter with the index ﬁnger until the desired effect is obtained.

This easy-to-use polarizing ﬁlter (available in linear or circular models) is much less costly

and cumbersome than similar systems and is of an incontestable quality. Its chromatic

neutrality is impeccable. In addition, because of its position in the ﬁrst slot of the ﬁlter-

holder, it produces no vignetting as do other polarizing ﬁlters that are positioned at the

front their ﬁlter-holders, farther from the front element of lens.

INDISPUTABLE OPTICAL & MECHANICAL QUALITY

COMPLETE MASTERY OF CR39

– 40 YEARS OF EXPERIENCE

COKIN is not only a manufacturer of “square” filters, but also its own organic CR39

glass. This guarantees the perfect mastery of optical quality. The remarkable

optical transmission of the Z-PRO filters allows for their use not only in digital or

film photography, but high-definition video (HD) as well.

Beyond the production and treatment of organic glass in its own factories, COKIN

works with numerous materials such as aluminum, mineral glass and high-tech PVC

derivatives. This diverse knowledge – protected by numerous patents – is the fruit

of 40 years of experience in optical mechanics. COKIN’s worldwide notoriety is

indisputable; COKIN is even a proud supplier to NASA!

OPEN SYSTEM, AS TECHNICALLY PRECISE AS IT IS IMAGINATIVE

PRO FORMAT – COMPLETE LINE IN CONSTANT EVOLUTION

The 100 mm format (4’’) is the professional standard. Z-PRO ﬁlter-holders therefore allow

for the use, beyond those of its own line, of numerous other ﬁlters of the same format (and

sometimes, of different thicknesses) designed by manufacturers such as Lee

, Schneider

or Tiffen

. Your “ﬁlter” choice is thus virtually unlimited.

Equipped with unrivaled ﬂexibility and adjustability, the Z-PRO ﬁlter-holder is accompanied

– to date – by a line of nearly 100 ﬁlters, several of which appear on the brochure cover

and are detailed on pages 32-48. New ﬁlters are currently in the testing phase and will be

available shortly (consult the website www.cokin-pro.com for more information).

MODERN, PERFECTLY ADAPTED TO DIGITAL

TIME-SAVING – EFFECTS UNATTAINABLE IN POST-PRODUCTION

The nearly full-scale adoption of digital photography by professionals has considerably

modified the production process of images. The time spent managing post-production

has seen a vast increase. Filtering images at capture leads to a considerable time savings.

Moreover, this streamlining of filtering workflow means that a good photographer is not

forced to acquire the specialized knowledge necessary to use complicated image-retouching

softwares... much less the expensive softwares themselves!

Finally, certain effects are quite simply unattainable in post-production, like the elimination

of reflections by using a polarizing filter, or the mastery of the difference in contrast

between the sky and the foreground in landscape photography by using a neutral density

graduated filter. Finally, no manipulation of curves or levels will ever allow you to recuperate

a totally burned out sky, devoid of all visible content!

THE 7 STRONG POINTS OF

THE Z-PRO SYSTEM

UNIVERSAL & TIMELESS

FILM – DIGITAL – HD VIDEO

The size of the Z-PRO ﬁlter-holder covers all current formats: 35 mm SLR, medium format,

large format, and panoramic; digital backs; HD video cameras; for Cinema, both 16 or 35

mm ﬁlm cameras. The system is adaptable to all lenses up to 96 mm in diameter.

Created almost 40 years ago, COKIN ﬁlter-holders defy time while being constantly

perfected with each passing generation. The Z-PRO is the latest model and therefore

beneﬁts from all of the knowledge accumulated by the ﬁrm over the past 40+ years.

Opting for the COKIN Z-PRO System is an intelligent choice. No matter what lenses you

may buy later, no matter what equipment you may use in the future, the durability and

relevance of your investment in the system are assured!

PRACTICAL & WELL-CONCEIVED

MODULAR – RELIABLE – LIGHT AND NON-CUMBERSOME

Both the Z-PRO filter-holders and the specialized bellows are completely modular:

without a single tool you can regulate, in next to no time, either the number of

filters used simultaneously or their thickness (1.6 to 2 mm, or 4 mm). Both adapt

to all configurations. The filter-holder’s coupling with an adapter ring that firmly

clicks it into place is foolproof, instantaneous, and guards against accidental

disengagement (during the insertion of a filter, for example). The Z-PRO filter-

holder is ultra-light (70 g) while remaining perfectly solid. Each square filter is in

CR39

glass and is sold in an ultra-flat pouch (4 mm) which weights barely 20 g (30

g for graduated). Thus, a complete set of a dozen filters, together with its filter-

holder and two adapter rings, measures only 7.5 cm in width and weights less than

630 g. The Z-PRO System is a masterpiece of ingenuity and always finds its place in

a shoulder bag... always ready to go to work...

EXEMPT FROM VIGNETTING*

INTEGRATED WIDE-ANGLE FILTER-HOLDER - REVERSIBLE

Thanks to its well-researched design, the Z-PRO ﬁlter-holder in a 3-ﬁlter conﬁguration

leaves only 24 mm of space between the ﬁlter and the front of the lens! Thus, in 35mm

photography, there is no visible vignetting with a 20 mm lens. The thinness of the adapter

rings helps to achieve this goal. For this reason, there is no need for special adapter rings

for use with wide-angle lenses...

In a single-ﬁlter conﬁguration, the ﬁlter sits 10 mm closer to the lens and the Z-PRO system

is thus transformed into a veritable super wide-angle ﬁlter-holder. There is no need of a

screwdriver nor the purchase of “special” wide-angle holder, ... In this way, the use of a

17~40mm zoom lens is free of any vignetting whatsoever. In extreme cases, as with an 18

mm lens, the Z-PRO ﬁlter-holders can be used in reversed position. This leaves a gap of

only 13.5 mm between ﬁlter and lens!

The COKIN Z-PRO System offers the best ratio

optical quality/cost/versatility/efﬁciency

to cover ALL your lenses up to Ø 96 mm
