I just got my EOS 70D from Amazon, then I tested few shots, i got frustrated because there were some dark spots on my images. So, i ran a thorough test on the issue. The test result just made me more frustrated and disappointed. I know it's normal to get dust on your sensor, but this camera is brand new, I can't tolerate this and I am returning to Amazon.
