● ❹ 3. Hood (Sold Separately)
The ES-52 hood can keep unwanted light out of the lens, and also protects the
lens from rain, snow, and dust.
When attaching the hood, securely attach it to the filter mounting thread (ø52mm)
on the front of the lens, or to the thread (ø52mm) on the front of the filter that is
already fitted to the lens (excluding older Canon circular polarizing filters that do
not have a filter mounting thread on the front) ❹ .
Part of the picture may be blocked if the hood is not attached properly.
4. Filters (Sold Separately)
You can attach filters to the front of the lens, or to the filter mounting thread
(ø52mm) on the front of the hood.
● Only one filter may be attached.
● Use the Canon Circular Polarizing Filter PL-C B (ø52mm) as the
polarizing filter.
● You can use hoods and filter attached in any order.
5. Extension Tubes (Sold Separately)
You can attach extension tube EF12 II or EF25 II for magnified shots. For
shooting distance and magnification, see the extension tube specifications.
MF mode is recommended for accurate focusing.
● The lens length is measured from the mount surface to the front end of the
lens. Add 21.5 mm to include the E-52 lens cap and dust cap, and 23.9 mm for
the E-52 II.
● The extenders cannot be used with this lens.
● The close-up lenses cannot be used with this lens. (The end of the lens will
become heavy, causing the focus to become unstable.)
