ND Drop-in Filter for Canon RF/EF Adapter

Kolari R Drop-in Neutral Density Filters give you precise exposure control in bright lighting conditions. Available in fixed strengths, these ND filters allow you to slow shutter speeds for motion blur, shoot wide open in daylight, or achieve cinematic motion cadence. Crafted with premium optics and coated for reduced reflections, they’re ideal for landscape, video, and long exposure photography.

Kolari R Drop-in Filters for Canon EF-EOS R Lens Mount Adapter (EF/EF-S to RF) are designed with both durability and usability in mind. Each filter is machined from solid aluminum with a wide grip and a lanyard attachment point, offering lightweight strength, secure handling, and user-friendly customization. Our precision-fit attachment system applies just the right amount of pressure, making it easy to swap filters intuitively—while ensuring they stay firmly in place during use.

All Kolari R Drop-in Filters for Canon EF-EOS R Lens Mount Adapter (EF/EF-S to RF) feature advanced AR (anti-reflective) and AS (anti-smudge) coatings for improved light transmission, reduced reflections, and easy cleaning. Our IRND filter options are built on ultra-strong Gorilla Glass substrates for unmatched optical clarity and resilience.

Kolari Pro 1-Stop ND – Reduces light by 1 stop (2× reduction), ideal for slightly darkening an image without drastically altering exposure. Perfect for subtle motion blur or shooting at wider apertures in bright light.

Kolari Pro 2-Stop ND – Cuts light by 2 stops (4× reduction), great for softening bright light while preserving color accuracy. Allows for slightly slower shutter speeds without overexposing.

Kolari Pro 3-Stop ND – Reduces light by 3 stops (8× reduction), a versatile choice for controlling depth of field in daylight. Perfect for softening motion in water or foliage while keeping a balanced exposure.

Kolari Pro 4-Stop ND – Cuts light by 4 stops (16× reduction), excellent for slowing shutter speeds in bright daylight to create smooth motion effects. Ideal for cinematic shutter angles outdoors.

Kolari Pro 5-Stop ND – Reduces light by 5 stops (32× reduction), perfect for adding more pronounced motion blur to moving water, clouds, or crowds. Helps maintain wide apertures under strong sun.

Kolari Pro 6-Stop ND – Cuts light by 6 stops (64× reduction), great for long-exposure photography during the day, producing silky water and streaking clouds. Also useful for precise exposure control in video.

Kolari Pro 7-Stop ND – Reduces light by 7 stops (128× reduction), enabling extended exposure times for dramatic motion effects without overexposing in bright conditions.

Kolari Pro 8-Stop ND – Cuts light by 8 stops (256× reduction), perfect for creative long exposures such as removing moving people from busy scenes. Maintains natural colors despite heavy light reduction.

Kolari Pro 10-Stop ND – Reduces light by 10 stops (1,024× reduction), a favorite for fine art photography. Turns oceans into glass and clouds into dreamy streaks even in midday sun.

Kolari Pro 15-Stop ND – Cuts light by 15 stops (32,768× reduction), extremely dark for multi-minute exposures in daylight. Ideal for surreal and abstract motion-blur effects.

Kolari Pro 20-Stop ND – Reduces light by 20 stops (1,048,576× reduction), allowing exposures lasting several minutes to hours in bright daylight. Perfect for ultra-minimalist, time-bending imagery.
