Learn how to choose the right Cine Series Mag Mount ND Filter for your lens size and shooting needs. Compare strengths, sizes, and the magnetic mount advantage.
Quick Answer
Choose the Cine Series Mag Mount ND Filter if you want fast filter swaps without threading—ideal for video and hybrid shooters who need consistent neutral color and IR reduction.
Magnetic Mount vs. Standard Screw-On
The built-in magnet mount lets you snap the filter on and off in seconds, which is a real time-saver when switching ND strengths between shots or lighting conditions. The trade-off is that the magnetic connection is slightly thicker than a traditional slim ring, so it may not fit under some lens hoods or with stacked filters. If you rarely change ND density mid-shoot, a standard screw-on filter might be simpler and cheaper.
Why IR Reduction Matters
When you use heavy ND filters (like 2.1 / 6-stop), the sensor can pick up invisible infrared light, causing a color cast. The Cine Series Mag Mount ND Filter includes an IR reduction coating to minimize that shift. This is especially useful for mirrorless cameras, which tend to be more sensitive to IR contamination. If you only shoot with lighter densities or in well-controlled studio light, IR reduction is less critical.
Decision Rules for Choosing Your Mag Mount ND Filter
- Pick the Right Size First: The filter is available in 67mm, 77mm, and 82mm. Match the diameter printed on your lens barrel or lens hood. If you have multiple lenses with different thread sizes, buy the largest size and use step-up rings.
- Choose ND Strength by Your Light: ND 0.3 (1-stop) is for bright sunny days at wide apertures. ND 0.6 (2-stop) works for moderate sunlight or adding motion blur. ND 1.2 (4-stop) handles midday sun or slowing shutter for video. ND 2.1 (6-stop) is for long exposures or filming at f/1.4 in full daylight. If you are unsure, start with ND 1.2 (4-stop) as the most versatile for both photo and video.
- Consider a Multi-Pack for Flexibility: Since swapping is magnetic, carrying two or three densities in your bag is easy. A 4-stop and a 2-stop cover most outdoor scenarios. The 6-stop is only needed for extreme conditions or specific creative looks. Do not buy all four densities unless you shoot in very varied conditions daily.
