Hello!

I have a quick question on a recent purchase. I recently purchased this:

Link to Product on B&H

I went out on the street where I live to try it out. I noticed on these images the green and magenta haze. It was fairly sunny on this day.

Nikon D7100

Nikon AF-S DX Zoom-NIKKOR 18-55mm f/3.5-5.6G ED II

Exposure time: 30 seconds

Aperture f/25

ISO 100

Is this result normal? Am I doing something wrong?

My guess would be a light leak possibly involving a sensor or other reflection that could separate the colors; it's also possible that it's electronic leakage, but I doubt that.

Try shooting with the camera lens out of direct sunlight (maybe even covered with something) while looking into the full sunlit scene; this is always the recommended protocol for using heavy ND filters in daylight. You might try making the same exposure with the lens cap on and see what you get, just to confirm it isn't a defective filter.

PS: Such light leaks are generally NOT considered a defect for a camera or lens, but simply a limitation exposed by your extreme use of the camera. If you think about it, dropping the light by 10 stops is dropping the light by pretty much the entire dynamic range of many cameras -- thus, the leaks you see would literally be below sensor noise if you weren't using this ND filter.
