- Durable Hoya glass construction provides consistent optical performance
👎 Cons

Frequently Asked Questions
How much light does the ND4 filter reduce?
The ND4 designation means it reduces light transmission by two stops (to 25% of incoming light), allowing you to use slower shutter speeds or wider apertures than conditions would otherwise permit.
What does the HMC coating do on this filter?
Hoya's HMC (Hoya Multi Coating) is applied to both sides of the glass to reduce reflections, flare, and ghosting, helping maintain image sharpness and contrast.
Will this filter add a color cast to images?
Neutral density filters are designed to reduce light without altering color. The Hoya ND4 HMC is built to remain color-neutral across the visible spectrum.
What lens thread size does this filter fit?
This filter fits lenses with a 49mm front filter thread. Check your lens cap or lens barrel for the thread size marking.
Can this filter be stacked with other filters?
Yes, it can be stacked with other filters, though stacking multiple filters on wide-angle lenses may introduce vignetting at the corners of the frame.
