The Canon Eg series Super Precision Matte Eg-S Interchangeable Focusing Screen enhances manual focusing via the viewfinder, particularly on subjects in low light conditions, when u tilizing lenses with a wide aperture ranging from f/1.8 to f/2.8. This 'S' type focusing screen functions by diminishing the focus of slightly out-of-focus regions surrounding the in-focus subject, resulting in improved contrast. Compatible with Canon EOS 5D Mk II and 6D 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 Show more
