The following is intended to be an objective real world test. I placed the camera on a tripod, used the mirror lockup function in addition to remote timer, non adjusted focus between shots, no camera movement, just ISO adjustment. Av mode was used, files were shot in RAW. files were converted to JPG at same time using same settings no noise reduction via adobe camera raw.
