Via SCSI Cable - SCSI is a form of image transfer involving a high speed bus cable system, used mainly in Macintosh computers and newer PCs. This method is relatively slow in comparison to a USB cable connection, but it's still quite commonly available. It is important to note, however, that this type of connection can only be used with newer Pentium computers, and it won't work on PCs with slower or older processors. This gives you the opportunity to save about 150 megabytes of pictures onto a disc that will slip into you computer's CD-Rom drive, where you can copy the pictures straight to your hard drive. This feature will tend to make the camera larger and bulkier, and you won't be able to copy over your pictures once you close the disc, but you may prefer the ease of transfer.
