1. PC SHOOT AUTO When a camera is not connected to a PC, images are recorded in an SD card. When the camera is connected to a PC via a USB cable, images are recorded to the PC by using the optional accessary "Tethered Shooting Software HS-V5". However, if the USB cable comes off during the transfer of the images, the images which have not been transferred will be lost.
2. PC SHOOT FIXED When the camera is connected to a PC via a USB cable, images are recorded to the PC by using the optional accessary "Tethered Shooting Software HS-V5". Once the camera is connected to a PC, images are recorded in the buffer memory (not in a SD card) in the camera. So, in the case the USB cable comes off during the transfer of the images, you can transfer them to the PC later unless you turn off the camera.
3. MTP(PTP) : default setting The setting is for normal shooting. You need to select this mode when you transfer recorded images to a PC via a USB cable and print them with PictBridge.
