The adjustable JJC F-RCND77 TrueColor ND2.5-ND1000 filter uses high-definition optical glass and a TrueColor coating for accurate color reproduction, preventing noticeable color shifts. With 14 layers of coating on each side, it offers low reflectivity and is resistant to water, oil, static electricity, and fingerprints.

• Ability to control exposure and shutter speed
• Adjustable range from ND2.5 to ND1000 (reduces light by 10 stops)
• Adjustable ND TrueColor filter without yellow tint
• Ultra-thin aluminum alloy frame, no vignetting, no X-shadow

This innovatively designed filter is divided into two groups: the first group is adjustable from ND2.5 to ND32 and offers five-stop exposure adjustment. The second group features an ultra-thin fixed ND32 filter to reduce light from ND64 to ND1000.

The design of the ultra-thin aluminum alloy frame eliminates vignetting and X-crossing effect, ensuring image quality even at a focal length of 15 mm.

The following test equipment shows no signs of vignetting or X-crossing at wide-angle focal lengths:

• Canon EOS R5 + RF 15-30mm F4.5-6.3 IS STM
• Canon EOS 6D Mark II + EF 16-35mm f/4L IS USM
