When one talks about a sequence of images recently taken getting caught up in a corruption situation, one should remember that it takes the Sigma a long -- as in, very long -- time to write images to card. It wouldn't surprise me, if a corruption situation presents itself, to have a number of images, shot within the past minute or more, to be affected also. Once I have hit the buffer, with six or seven shots in quick succession, it takes an inordinate (by the standards of virtually any other modern digital camera) to write each image to card and thus clear the buffer for another shot. I haven't actually timed it, but I wouldn't be surprised to find a 10 second (or more?) write time for each image. I love the results from these cameras, and thus am resigned to living with this. Knock on wood, I don't recall a problem with corrupted files. --Barbara
