NOTICE: The Library is continuing to work on the transition to a new and improved library management system. As the transition continues some functions and services will continue to operate at a limited capacity. Users can still check out and return items and search the catalog. Users will not be able to log in to their library accounts, request items online, or use self check-out machines. If you have questions please email email@example.com or call (202) 687-7607. Thank you for your continued patience during this transition.
The EF 100mm f/2.8 Macro USM Lens from Canon will focus over the full range from infinity to true life size (1:1 reproduction ratio) macro. Ideal for photographing details and small subject material, it also serves as a very sharp prime telephoto lens for portraiture and other applications. It provides a combination of versatility, image quality and superb handling.
The 0.3-2.55 density can easily be controlled by rotating the front filter ring, allowing you to slow your shutter speed or work with a wider aperture setting than normally required. By offering the ability to adjust different density values, this filter can effectively be used in a wide range of situations and controlled to meet your exposure needs.
