When I looked for The Memory Stick Pro Duo at the online store, I found that the price is more expensive than the micro SD card, with the same speed and the same capacity. It was not good idea if determined to buy because it is only for the old camera.
finally I found a solution, found at the online store the converter for micro sd to Memory stick Pro Duo, the price is very cheap. So I can use my micro SD for my Sony camera with this converter.
I have no problem with the camera using this converter,
Now I can take pictures again with my favorite camera.
I you have the same problem, maybe you can also use this converter for solution.
