Astronomik OWB Clip Filter for Canon EOS M

No, this filter is specifically designed for cameras that have undergone full-spectrum or infrared-cut modifications. If your camera has its original factory sensor, this filter is unnecessary and will likely interfere with your standard color balance.

Modifying a camera sensor for astrophotography often removes the internal infrared-cut filter, which shifts the color balance significantly. The OWB (Original White Balance) filter restores the spectral response to normal, allowing you to use your camera for standard daytime photography with accurate colors.

The clip-in design sits inside the camera body, directly in front of the sensor. Because it is positioned behind the lens mount, it is compatible with all lenses that fit the Canon EOS M mount, regardless of the lens's own filter thread size.

No, the filter is crafted from diffraction-limited optical glass, ensuring that it does not degrade image sharpness or contrast. It is designed to maintain high optical performance even when used with high-resolution lenses.

A parfocal design means the filter is engineered to have the same optical thickness as other Astronomik filters. This allows you to swap filters in your imaging setup without needing to refocus your lens every time.

Yes, the filter features a scratch-resistant, durable coating designed to withstand regular handling. It is also resistant to high humidity and aging, making it reliable for long-term use in various environmental conditions.
