ENG - Review Kase 112mm Wolverine Magnetic Circular Filter for Nikkor Z 14-24mm f/2.8 S

Atualizado: 22 de Dez de 2020

In September 2020, Nikon launched the Nikkor Z 14-24mm f / 2.8 S lens for its mirrorless system and the great novelty of this lens is that it can attach a circular filter, by means of a thread, to a specific hood that accompanies the lens.




The measure caused some strangeness since 112mm is not a circular filter standard, however Kase Filters hurried to give the market filters of this measure, both in a threaded and magnetic version, the latter being the ones I went to test for this review.



1 - Magnetic ring 112mm



In order to make the system more versatile and easier to use, Kase Filters created a 112mm aluminum magnetic ring, equipped with a thread that will be placed on the hood.

Light and easy to install, it does however require verification that it is properly screwed on.



Once installed, this ring will be a base for all other filters that we want to use. Because it is magnetic, it allows a filter to be placed quickly and easily, "sticking" to the ring.

This ring is supplied with each filter, however, unless you use other non-magnetic screw filters, there is no need to remove it, avoiding future waste of time.



As all Kase Filters magnetic systems, the filters are placed with the legend facing inside (letters facing the ring side).

This system also allows you to stack several filters.


2 - 112mm Wolverine Magnetic Circular Filter


Made of KW optical glass, shock resistant and scratch resistant (Wolverine), they have anti-reflection treatment (multicoating) on both sides as well as water / oil repellent, making cleaning easier.

Frame: 6063 lightweight Aluminum + Magnet, 4.2mm thickness


Filters offered by Kase Filters for this system:

- ND (3, 6 and 10 stops)

- GND (3 stops)

The elegant packaging comes with a plastic box with a transparent lid that accommodates a magnetic ring and the chosen filter.

Summary:

Easy installation by magnetism, either in the dark or in the cold (Kase is the only brand that launches 112mm magnetic filters).

Made of Wolverine KW glass, it shock resistant.

The Reticulate design, avoid filter slip off.

No light leakage.

Thin design avoids the vignetting when stacking more than 2 filter on the lens.

In general, it can be said that the tested filters surprise by the quality of the tuning of the stops, with almost perfect or very correct exposures. Without showing clear changes in tonality, the little it presents is not worrying.

The size of the filters compared to the diameter of the lens, does not allow them to create vignettes.

Image sharpness is not called into question.
