I bought it to photograph wildlife during our next African safari, but for the lack of any local leopards or lions, I decided to use this lens for the next best subject: the moon.
Here, on 6 September, 2014, the moon is in Waxing Gibbous phase.
I headed outside earlier this evening to photograph the moon, which was a challenge given the heavy cloud cover that was blowing over.
During one of a few short windows of opportunity, I captured this frame.
Ignore the focal length of 800mm; I actually shot this at 1,120mm as a result of having stacked both my 1.4x and 2x tele-converters; but when stacking more than one tele-converter, the focal length and aperture are not transmitted to the camera, so it appears that I used only my 2x tele-converter.
As I type this, the moon is undergoing a partial eclipse.
I don’t often shoot the moon (it’s been done to death, and I had great success during the 2007 eclipse), but given the easy opportunity and the lack of effort required, I went outside with 600mm of focal length and captured this image of the partial eclipse:
Lunar Eclipse on 26 June, 2010
I used my Canon EOS 5D Mark II, Canon EF 300mm f/2.8L IS USM, Canon Extender EF 2x II, a tripod, remote cable release and mirror lockup.
Photographed at 9:16pm on 26/06/2010 with a Canon EOS 5D Mark II at 600mm for 1/160 sec at f/8 and ISO 200.
