Full moon with Canon 300mm and two 2x extenders.

Recommended Posts


This shot of the full moon turned out better than expected due to me using two 2x extenders. It was a last minute decision to take both extenders with me.

  • Canon 5D III
  • Canon 300mm f4 L IS lens
  • Canon extender EF 2x version 1
  • Tamron tele-converter 2x
  • Equivalent to 1200mm f16
  • ISO 500
  • 1/100 second
  • f 32 (2 stops above wide open - f8 > f16 > f32)
  • Image is un-cropped

  • Canon 5D IV  ??
  • Sigma 150-600mm at 600mm ??
  • Canon extender EF 1.4x or 2x ?? - but at 720p the extender might not be required.

Yes on 1 & 2. No on extender. Having that 1.74x crop on the 5D MkIV really helps for some subjects!  :)
