The Canon ET-73 Lens Hood is the dedicated OEM hood engineered specifically for the Canon EF 100mm f/2.8L Macro IS lens, delivering a precise fit that guarantees zero vignetting at any shooting distance. Designed by Canon to match the exact optical geometry of the L-series macro lens, it slots on seamlessly and stays secure during even the most dynamic macro or portrait sessions.
By extending and shading the front element, the ET-73 blocks unwanted stray light and harsh glare before it can degrade contrast, colour accuracy, or sharpness in your images. As a welcome bonus, the extended barrel also acts as a physical bumper, protecting the precious front glass from knocks and accidental impacts in the field.
Key features
- Glare-free images: Engineered to prevent stray light from striking the front element, preserving maximum contrast and colour fidelity in backlit or bright conditions.
- Zero vignetting guaranteed: Precision-designed geometry matches the EF 100mm f/2.8L Macro IS exactly, so corners stay perfectly exposed at every aperture and focus distance.
- Front element protection: The extended hood barrel acts as a physical shield, guarding the lens against accidental bumps, dust, and light splashes during close-up macro work.
- OEM Canon fit: Genuine Canon accessory with a secure bayonet mount that attaches and reverses for compact storage without tools or adapters.
- Lightweight & unobtrusive: Adds negligible weight and bulk, making it ideal to leave permanently attached whether shooting portraits, product photography, or detailed macro subjects.

Frequently asked questions
Which Canon lens is the ET-73 hood compatible with?
The Canon ET-73 is designed exclusively for the Canon EF 100mm f/2.8L Macro IS lens. It is not recommended for other lenses, as the geometry is matched precisely to that optic.
Will the ET-73 cause vignetting or dark corners in my photos?
No. Canon engineered the ET-73 specifically for the EF 100mm f/2.8L Macro IS, so it will not produce any vignetting at any aperture or shooting distance.
Does the lens hood offer any physical protection for the lens?
Yes. Because the ET-73 extends beyond the front element of the lens, it provides an added buffer against accidental impacts, helping protect the front glass during macro or outdoor shooting.
