20090720 Sun

The typhoon left rather quickly. Today we got around 60-70% of cloud cover, and the weather forecast is very favorable on the eclipse day locally, and at least I won't be making too bad a decision to stay.

Today I tried to shoot in white light again with my camera lenses so that I can see how to make good use of them. Autofocus by using LiveView contrast detection is better than conventional DSLR focusing when there is no sunspot to focus, but contrast detection using the solar disc edge could be very accurate! Better yet, you're not limited by the aperture, autofocus is available even at f/11!

Again, I tried the 200mm f2.8L with Kenko 2x as well as the Canon 100-400mm f4.5-5.6L with kenko 2x.
