I have photographed Solar Eclipse on a cruise in South Pacific in 2012. There are 2 important setting. bright sun with solar filter and totality without filter. As far as solar filter photography it is easy because you have time and are able to practice days before. With totality you have one chance in lifetime lasting 2 minutes.I was using Nikon D7000 with 18-200mm lens,.Solid tripod, cable release, single point auto focus. I have pre-set U1 and U2 for totality. All my images were sharp and my best image of Diamond ring was in landscape mode. Most people I spoke to have photos out of focus because of the decision to use manual focus. Don't do it. .
