This Ef series Precision Matte Grid Lines Ef-D Interchangeable Focusing Screen from Canon provides three horizontal and five vertical etched grid lines to facilitate easier composition and horizon alignment.
This "D" type focusing screen assists in keeping straight lines in a subject straight, positioning subjects off-center, or by keeping compositions in a series consistent from one shot to the next. The camera's AF points remain fully visible when using this screen.
- Compatible with Canon EOS 40D, 50D, and 60D
- Focusing screens are delicate and should only be handled using the included tool for installation
