Cokin CH150B52A overview

  • 1Description

The Cokin 52mm PURE Harmonie Variable Density Neutral Gray Filter is a solid variable neutral density filter providing a reduction of about 1 to 8 stops. The 0.3 to 2.4+ (ND2-ND300) density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. The degree of density is easily controlled by rotating the front filter ring, allowing you to previsualize the additional exposure length required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. For easier, repeatable control over density settings, the front ring is also visually demarcated with dots that each represent one stop of neutral density.

The EVERCLEAR 5 Coating Technology is a multi-layered anti-reflective coating applied to the filter substrate in order to maintain effective light transmission and suppress surface reflections and flare. Additionally, the coating provides protection against five distinct elements: water, oil, dust, soil, and scratches.

This optical glass filter is set within a thin aluminum filter ring, which measures just 9.5mm-thick. This slender profile is ideally suited for use with wide-angle lenses in order to lessen the likelihood of vignetting.

Variable neutral density filter allows you to dial in differing amounts of density scene to scene.
ND 0.3 to 2.4+ filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.
Providing a reduction of 1 to about 8 stops, this filter allows you to control depth of field and convey movement more easily.
Filter does not affect coloration of the image.
Anti-reflective EVERCLEAR 5 multi-layered coating helps to protect the filter from water, oil, dust, soil, and scratches, in addition to maintaining image contrast and reducing lens flare and ghosting.
Thin aluminum filter ring measures 9.5mm-thick, making it ideal for use with wide angle lenses in order to prevent vignetting.

    Cokin CH150B52A reviews

    52mm PURE Harmonie Variable Density Neutral Gray Filter is rated 3.0 out of 5 by 2.
    Rated 1 out of 5 by from Degrades image quality I tested this with Olympus E-M5 and 4 lenses: Olympus 8-19, Panasonic 14-45, 45-200, 25 (with a step up ring). The Good. The filter is thin and does not create any vignetting even at 9mm. It is easy to use. Convenient, one filter instead of several. The Bad. Once filter is attached it is not possible to attach a lens hood with any of the above lenses, because it is wider on the outer end (I suppose it was designed for ultra wide lenses). With 8-19 and 14-45 it can be attached after the hood, but it is a real pain. With the other two - not possible. Unless you buy a hood that screws into the thread on the filter. Degrades picture quality. With 8-19 there is a slight decrease in sharpness, and two corners of the picture (bottom right and upper left) become lighter than the other two corners (so called cross effect). It gets more pronounced closer to the maximum setting. With 14-45 the sharpness degrades more, but pictures could still be usable. 45-200 is completely unusable due to loss of sharpness which degrades with longer focal length. The filter itself works as a lens. Manually focus the lens without filter, attach the filter and focus is gone, it needs to be refocused. With 25 the filter degrades sharpness to the point where it does not make sense to use it with this lens. Makes colors noticeably warmer. I am going to return it.

    Rated 5 out of 5 by from Does What It Says It Will Do Used this for longer exposure without needing to stop down. I assume this works via circular transitioning so if you're not careful, you may end up with an uneven exposure. You just need to pay attention to what you're doing.
