You might inadvertently use a part of the viewfinder that has an aerial image. Modern cameras are unlikely to have any aerial image sectors on their screens, but if you have a replacement screen with a split image or microprism you need to beware. The amount of parallax possible with one of these would admittedly be exceedingly small but it never hurts to be careful.
