Canon Ee S Focusing ScreenThe Canon Ee s Focusing Screen is an all-matte focus screen for the Canon EOS 5D. Designed to facilitate manual focusing with high-speed lenses (f/2.8 or faster). The Ee-S screen has finer microlenses than the Ee-A or Ee-D options, along with a steeper parabola of focus to make the image pop in and out of focus more vividly in the viewfinder. It gives more confidence in the accuracy of autofocus and is especially recommended for manual focus. Even in low light, the reduction in viewfinder brightness is offset by the ease of getting the focus point just right. The screen gives an accurate representation of what is actually in focus and ultimately makes it easier for the user to get a clear focused picture using manual focusing. The Ee-S focusing screen however, is not recommended for slower lenses because it?s not very bright. The EOS 5D must be set to Custom Function 00-2 for accurate exposure metering. !!
