First point this device has a dust defect due to manufacture. Only the former were affected, but how do you know if you are going to receive is not party. Secondly the D610 1647.39 sold in your store and D600 was selling at least 1250 before the release of the D610 (same device but the inner shell is made of another material causing no dust ...). Buy this camera is a lottery in itself, then at that price ever in life!
