Sony bought all of the Konica Minolta camera division.
They also have the responsibility for support of the Konica Minolta equipment.
Now that responsibility has expired.
To let you know the current situation;
Here is a link that will eventually take you to a place that may be supporting your product:
I've just bought a secondhand Konica Minolta Dimage A2 dslr. Worked great untill i tried to update the firmware and now camera is locked up. This is due to a fault in the firmware update instructions and I have found posts of this happening elsewhere. What I cannot find is any way to 're-boot' the camera. It just displays a low battery warning and will not respond to any other controls.
Any ideas much appreciated as the manufacturers no longer exist.
