I got them here....from 2002.
I believe you are right. Sony does NOT support this old model. The software supplied with the camera is not compatable with Vista,however the USB driver is included on the CD and this driver is incompatable with Vista. I have no interest in the imaging app: "Picture it". I only want to load the images to my computer by usb.
I was hoping someone could suggest another USB driver that might work. I tried a few on the Sony site but none worked. It was trial & error for an hour.
FWIW....I went through the same problem with my DCR-TRV460, but WAS able to download alternate software from Sony to enable it for Vista.
I guess the DSC-F505 is too damn old...
Slainte!
