400D/40D BCF Baader Corrector Filter
Planoptically polished filter with improved spectral transmittance
Suitable for the following Canon EOS models:7D/40D/50D/60D/400D/450D/500D/550D/600D/650D/700D/1000D/1100D
This filter replaces the LPF2, which is the filter directly in front of the sensor.
To achieve the same level of professional use of these cameras the thickness had to be kept very close to the thickness of the original Canon filter, therefore Baader achieved that this filter can differ from the original by only 1/100mm.
Be very carefule when handling this filter, it's thickness is just few hundredths of millimeters above 0.5 mm.
