Once you have used the TV screen, you only noticed not much - except that the viewfinder image is considerably darker. But once you but then focused to show the full strength of the EF-S; It's much easier and more accurate by hand. The bought one, however with a darker viewfinder. So if you - like me - often times is to inserts with a dim place, which should vorschnallen at least one f / 2.8 optics or faster or reinstall earlier quickly the standard focusing screen. The conversion is slight of hand and is done in two minutes. All tools are supplied. The focusing screen fits into a solid plastic construction. A conversion guide is enclosed. You need but only once. Do not forget to enter the TV screen in the C-Fn of the camera! Otherwise there is incorrect exposures!
