Overview
Achieve Perfect Exposure with Infrared Control
The Tiffen W405IRND12 is a 40.5mm filter that combines neutral density (ND) and infrared (IR) reduction, reducing ISO to 1/16. Designed to provide greater latitude when editing in post-production, this filter ensures vibrant colors and eliminates IR contamination by not compromising the color gamut.
Specifications
- Filter Size: 40.5mm
- Filter Type: Combination Neutral Density (ND) 1.2 Infrared (IR)
- ISO Reduction: 1/16
Key Features
High quality filter to prevent the color shift caused by the sensitivity of today's digital sensors
Tiffen filters are manufactured using ColorCore technology, a closely guarded proprietary process that entails permanently laminating the filter material in between two pieces of optical glass that are ground flat to tolerances of a 10,000th of an inch, then mounting them in precision metal rings
The ColorCore process allows Tiffen to control the color and density of their filters and the characteristics of special effects filters with much greater accuracy than typical dyed-in-the-mass filters, which usually exhibit color and density variations
Natural Density Filters enables slow shutter speeds to be used, especially with high speed films, to record movement in subjects such as waterfalls, clouds, or cars
Natural Density Filters decreases depth of field by allowing wider apertures to be used, which helps separate subjects from their background

Pros & Cons
👍 Pros
- Specifically designed to prevent color shifts caused by the sensitivity of modern digital sensors, ensuring accurate color reproduction.
- Manufactured using Tiffen's proprietary ColorCore technology, providing precise control over color and density.
- Achieves greater accuracy in color and density compared to typical dyed-in-the-mass filters, reducing variations.
- Enables the use of slower shutter speeds, ideal for capturing motion blur in subjects like waterfalls, clouds, or cars.
- Allows for wider apertures to be used, which helps in decreasing depth of field and separating subjects from their backgrounds.
- Features a 40.5mm size, compatible with lenses requiring this specific filter diameter.
👎 Cons
- Requires a 40.5mm lens thread size, meaning it will not fit lenses with different diameters without an adapter.
- The IRND 1.2 density provides a specific light reduction, which may not be flexible enough for all lighting conditions without stacking filters.
- While preventing color shift, it is still a neutral density filter, which darkens the image and requires longer exposure times.
- The benefit of ColorCore technology is primarily internal, and not a direct user-adjustable feature during shooting.
- May be perceived as a higher-cost option due to the advanced manufacturing process compared to basic ND filters.
- Requires careful handling to maintain optical clarity, like all high-quality filters.
Frequently Asked Questions
What is the primary purpose of the Tiffen W405IRND12 filter?
The primary purpose of this filter is to prevent color shift caused by the high sensitivity of today's digital sensors and to control the amount of light entering the lens.
How does Tiffen's ColorCore technology benefit this filter?
ColorCore technology involves permanently laminating the filter material between two pieces of optical glass, which allows Tiffen to control the color and density with much greater accuracy than typical dyed-in-the-mass filters.
Can this filter help me create motion blur effects in my photos?
Yes, as a Natural Density Filter, it enables the use of slow shutter speeds, which is ideal for recording movement in subjects like waterfalls, clouds, or moving vehicles.
What effect does this filter have on depth of field?
This filter decreases depth of field by allowing wider apertures to be used, effectively helping to separate your subject from its background.
What is the filter size of the Tiffen W405IRND12?
This specific filter has a diameter of 40.5mm, making it suitable for lenses with a matching filter thread size.
