Hoya 67mm HRT CPL+UV Filter: What It Does

Learn how the Hoya 67mm HRT Circular Polarising+ UV filter combines two essential lens filters in one, reducing reflections and protecting your lens.
Quick answer
The Hoya 67mm HRT Circular Polarising+ UV filter removes unwanted reflections from non-metallic surfaces while also blocking UV light and protecting your lens—ideal for outdoor and travel photographers who want two functions in one filter.
How the combined filter works
The HRT (High Resolution Technology) coating on this filter reduces flare and ghosting, which is especially helpful when shooting in bright conditions. Because the polarizer and UV functions are built into a single piece of glass, you avoid stacking filters—which can cause vignetting on wider lenses.
However, a combined filter means you cannot use the polarizer independently from the UV protection. If you only need UV filtration (e.g., for haze reduction) without polarization, a separate UV filter gives more flexibility.
When a combined filter makes sense
This filter is most practical when you want permanent lens protection and occasional polarization. For example, landscape photographers who shoot near water or glass often want to cut reflections, but don't want to swap filters constantly. The 67mm thread size fits many popular lenses from Canon, Nikon, Sony, and Fujifilm.
One trade-off: the polarizing effect is fixed—you cannot remove it without taking off the entire filter. If you shoot in low light or indoors where polarization isn't needed, you might be better off with a standard UV filter and a separate polarizer.
Decision rules for the Hoya 67mm HRT CPL+UV
- Choose this filter if: You shoot outdoors frequently and want to reduce reflections from water, glass, or foliage while also protecting your lens from dust and scratches.
- Skip this filter if: You need to use the polarizer and UV functions independently, or you often shoot in low light where polarization reduces the light entering the lens.
- Check your lens thread: This filter only fits lenses with a 67mm filter thread. Verify your lens's thread size (printed on the lens barrel or cap) before purchasing. Using a step-up ring can adapt smaller filters to a 67mm lens, but may cause vignetting.
Product facts
- Hoya 67mm HRT Circular Polarising+ UV filter: Light rays reflected by any surface become polarized; this filter selects which light rays enter your camera lens, removing unwanted reflections from non-metallic surfaces like water and glass. You can reduce glare on water or storefront windows without attaching a second filter, saving time and avoiding extra weight on your lens.
