Haida gray graduated filter ND 1.2 inverted for 150mm filter holder

Gray graduated filter for the Haida 150mm system - can be used on almost any lens

The M15mm system is considered the standard system for plug-in filters in the ultra-wide angle range. It is equally suitable for SLR cameras but also for mirrorless cameras.

With a compatible filter holder and the matching adapter ring, the filter can then be used on almost any of your lenses. You only need a matching adapter ring for each lens.

To achieve an even exposure on subjects with strong differences in brightness (e.g. land - sky), a gray graduated filter is used.

A gray graduated filter is divided into two zones, a clear zone and a neutral gray zone. The gray zone reduces the amount of light entering the lens. The clear zone allows light to pass through unobstructed.
This allows an even exposure of the image. Example: Sunset on a mountain range, the sky is very bright and the mountain is dark. With the help of the gray filter zone, the brighter area of the image is darkened and then the appropriate exposure is set for the darker area of the image. This ensures that the image is correctly exposed over the entire image area.

Available in different grayscales and with gradient boundaries of varying hardness
Haida gradient filters are available from us in a wide variety of versions. There are different versions with different dark gray areas. Differentiated in the gray levels and in the gradients of these gray levels.

Filters with hard gradients, i.e. with a very abrupt separation between the clear and the gray zone, are suitable for motifs with a clearly defined and straight horizon, e.g. sunset at the seaside
Filters with soft gradients are suitable for motifs with a less clearly defined horizon. These are, for example, slightly hilly mountain landscapes or landscapes in general.

Metal box for safe storage and transportation
The scope of delivery of the filters includes a metal box. This is perfect for transporting or storing the filter well protected.

The aperture reduction of ND filters is calculated as follows:

The density of ND filters is usually given in steps of 0.3.
To obtain the aperture reduction, first multiply the value by 10 and then divide by 3.

0.3 x 10 = 3 | 3 = 1 f-stop
0.6 x 10 = 6 | 3 = 2 f-stops
1.2 x 10 = 12 | 3 = 4 f-stops
3.0 x 10 = 30 | 3 = 10 f-stops
3.6 x 10 = 36 | 3 = 12 f-stops
4.5 x 10 = 45 | 3 = 15 f-stops
