Canon 0848B001 Overview

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.

Compatible with Canon EOS 1D Mk II N, 1D Mk III, 1D Mk IV, 1Ds Mk III, and 1Dx
Not recommended for ordinary zoom lenses with maximum aperture slower than f/2.8 as the screen will appear dark and grainy
Focusing screens are delicate and should only be handled using the included gripping tool for installation

question

Does this work only around a center focus point? Or if I change focus points, it will decreasing the focus of the slightly out-of-focus areas around my newly selected focal point?
Asked by: michael
This is really for manual focus lenses. It is a brighter screen so when you are manually focusing you can see the slight differences of what is and isn't in focus with your lenses. It will have zero effects on your camera's ability to auto focus.

question

As long as your maximum aperture is f2.8 or faster, this screen should be bright enough unless you're using the DOF preview, right?

question

Will this work with the 1DX-II?
Asked by: Anonymous
No, the Canon Super Precision Matte Ec-S Interchangeable Focusing Screen is not compatible for use with the Canon EOS 1D X Mark II DSLR camera. Canon USA's website only lists the Canon EC-C6 Focusing Screen, B&H # CAECC6, as compatible for use with the Canon EOS 1D X Mark II DSLR camera.
