Due to the big changes in the camera market, the demand for full format camera rooms with BCF-2 filters has unfortunately decreased so much that a production of these filters can no longer be justified. Therefore we offer the Canon Astro Upgrade Service from now on only for APS-C DSLR-Cameras.

Further information can be found on the product page Canon Astro Upgrade for all Canon APS-C DSLR-Cameras.

The product shown here – BCF-2 Filter for Full-Frame Cameras – will no longer be produced and will soon be removed from our website, thank you for your understanding.

  • DSLR Astro Conversion Filter (Baader-BFC2)
  • Planeoptically polished, with improved spectral transmission
  • Fits Canon Full-Format Cameras (all latest Models) as well as older such as EOS 5 D Mark II, Mark III and EOS 6D
