Baader BCF correction filter Canon

Suitable for Canon 40D/50D/400D/450D/1000D. By changing the built-in filter, the sensitivity in the important H-alpha range is increased many times over. The BCF filters are also suitable for daylight without the need for additional filtering. They achieve improved sharpness performance, reduced background noise by shortening exposure times and less color deviation in lens lenses due to steeper blocking of UV light.
