Features 1、Neutral density can adjusted from ND2 to ND400 to reduce the amount of colorless light reaching film. 2、When lens focal length in ultra wide angle range and aperture value of F2.8, if filter adjusted to high density using, relatively obvious "cruccross" spot or slight color shift may occur. To ensures that the image is not disturbed, we suggest that you lower the density value of the filter at this point until the disturbing light spot disappears, and then shoot normally. 3、With this filter, more free of controlling aperture and shutter can obtained, bringing more exposure means and creation space for photography creation, effectively preventing overexposure. 4、ND2 reduces exposure by 1, ND4 by 2, and ND8 by 3. The number after ND represents the ND mirror capacity to block light. 5、Professional manufacturing, suitable for dynamic screens, waterfalls, streams, waves, etc. Specification Condition: 100% Brand New Item Type: Lens Filter Brand: Junestar Material: Aluminum Alloy + Optical Glass Color: As Pictures Shown Fitment: For SLR/Mirrorless Camera Lens Weight: Approx. 41g Package List 1 x Lens Filter 1 x Storage Box
