Don't push ISO so high, it will be disturbed by noise. The original minimum ISO of 5D2 is 200, so it is more reliable to test with an ISO value of 200 or 400. Exposure time is longer, such as 10 second or even 30 seconds, so that pixels with poor health will appear. In addition, it is normal that the old machine has several bad points. If it is too much or too conspicuous, it will be shielded after sale.
