This product is not currently in stock, but is usually available from our supplier within 5-7 days of your order being placed.
For Canon EOS 40D and 50D digital SLR cameras, the Ef-S Focusing Screen (Super Precision Matte) is optimised for wide-aperture lenses from f/1.8 through f/2.8. Areas that are slightly out of focus appear more out of focus, making it easier to tell when focus is right-on. It is ideal for users who frequently manually focus in dim light with fast lenses. More
