I emailed a number of camera friends in Japan, and have received replies from most of them. Many live in regions like Tokyo, Osaka and Nagoya, so they are safe. One fellow has a number of photos of people stuck waiting for the train.
I also received a reply from Shinzo Fukui, the Sigma photographer whose stunning work for the DP2 catalogue made me buy that camera. He, his family, and all Sigma staff are safe and well. He also asked that I continue to support Sigma! And of course, I will. Japan can do with all the support it can get at this time.
