FOCUSING SCREEN EC-S (for 1DIIN)

Product description

Product description

    This Ec series Super Precision Matte Ec-S Interchangeable Focusing Screen from Canon provides easier manual focusing through your viewfinder on subjects in low light when using lenses with a wide aperture between f/1.8 to f/2.8. This "S" type focusing screen works by decreasing the focus of the slightly out-of-focus areas around your in-focus subject for a sharper contrast.

    The Canon Ec-S Focusing Screen with super precision matte makes it easy for professional photographers to determine the precise point of the sharpest focus during manual focusing shots. This is because the microlens on the screen's matte is optimally shaped to increase defocusing near the point of focus. For best results, Canon recommends using the optional Ec-S focusing screen with f/2.8 or brighter lenses. It is best suited for use with Canon's EOS-1D Digital SLR Camera.
