Photographing the Moon
Last night there were some patches of clear sky and the moon came out. I decided it would be a good opportunity to try out the 400mm telephoto lens and a 2x converter. I experimented with various settings, the shot above was ISO 400, 1/60, F8. It is surprisingly difficult to focus on the moon, you can’t just set the lens to infinity, but need to make micro adjustments. A more significant issue is that as the lens itself is mounted to the tripod, the rear converter and then the camera are hanging mid air. I think I could gain extra stability and sharpness by having the body mounted on a separate tripod, although this will make any changes in angle a pain. (The other option would be a custom double mount but I imagine this would be prohibitively expensive.) One of the other key points about this exercise is that sometimes smaller sensors are very useful. In this case, the advantage of having a large sensor was made redundant by the fact I was …
