Hello Peter, the camera uses four AA type batteries or 2 CR-V3, as I use to do. The batteries seems not to be wired in parallel, because the camera does not turn on with only one battery in the body, in one slot or other. Also, considering that each CR-V3 battery has a nominal voltage of about 3,7V, and that the external DC power supply is 6,5V, I think that they are wired in series, to supply the required voltage.

Hello Ad, in effects the lens used has no aperture ring, however I noticed in the last days that, inside the lens mounting hole, the small aperture control lever moves from one stop side to the other side quickly and repeatedly, until the camera is turned on.
I think to exclude a defect on-off-aperture control lever, because when I put it in the "aperture control" position, the problem stopped but it restarted when I have released that lever.
Today I turned on the camera and **"miracle"** the camera not started as usual to have that problem, I have used the menus in order to reset the function to factory settings, but I think that the problem is still there, because I noticed that the display lights up sometimes without any apparent cause.
It seems to me that there will be some defective contact in the camera's supply circuits, is like the power supply is removed and reconnected quickly many times.

Hello, my *IST DS, as soon as I turn it on, starts to set the aperture continuously at a rate of about 1 setting for second, and does not stop until the camera is on, all control buttons seems to have no effect, so I cannot use menus, or review images shooted, however the camera shoots correctly if I press the shutter release button.
Images are well shooted but I cannot see them as normally by pushing the review button, it is possible only inserting the SD card in the PC.
I tried to change lens with several others, to turn on camera without lens, to change batteries (well charged), to update the firmware (now 2.02), to well clean lens and camera contacts but the camera continues to set noisy the aperture, as long as it is on.
I tried to turn camera on keeping shutter release button pressed (it is a reset mode?) but no results.
Some ideas about?
Greetings
Giovanni
