yes, depending on the camera, you will most likely need a firewire cable. I have an old sony digital that I just finally bought a firewire cable. I talked to a sales rep at bestbuy and they told me what I needed and tried to sell me one for $36.99. I searched online and found the same cable for under $5.00 with shipping and had it in 2 days (standard shipping.)
