Quick answer

Replace a lost Canon EF 28-70mm f/3.5-4.5 lens hood with a compatible EW-68A replacement from Fotodiox. It attaches the same way as the original and costs a fraction of the price.

Why a lens hood matters for this lens

The Canon EF 28-70mm f/3.5-4.5 is an older zoom that benefits from a hood to reduce flare and protect the front element. Without it, stray light can wash out contrast, especially at the wide end.

A third-party replacement like the Fotodiox EW-68A hood does the same job as the Canon original at a lower price. It’s made from high-impact plastic and includes a 2-year warranty.

Compatibility check before you buy

This lens uses a bayonet mount hood with the EW-68A designation. Not all Canon 28-70mm lenses share the same hood—check your lens model (EF 28-70mm f/3.5-4.5) before ordering.

The Fotodiox replacement is specifically designed for that lens. If you have a different Canon 28-70mm variant (like the f/2.8 L), the hood mount is different and this hood will not fit.

Step-by-step installation

  1. Align the hood with the bayonet mount: Hold the hood so the wider opening faces away from the lens. Line up the bayonet tabs on the hood with the slots on the front of the lens barrel. The hood should sit flush without forcing it. If it doesn't line up, rotate the hood 90 degrees and try again.
  2. Twist clockwise until it clicks: Press the hood gently against the lens and rotate it clockwise (looking from the front) until you feel a firm stop and hear or feel a click. The hood should be locked in place. If the hood feels loose or wobbles, it isn't fully seated. Remove it and re-align before twisting again.
  3. Test the zoom and focus rings: With the hood attached, rotate the zoom and focus rings through their full range. The hood should not interfere with ring movement or block your fingers. Some wide-angle zooms show the hood edge in the frame at the widest focal length. Check your viewfinder at 28mm—if you see a shadow, the hood may be reversed or incompatible.
  4. Reverse the hood for storage (optional): To save space in your bag, reverse the hood by removing it, turning it around, and twisting it onto the lens backward. The wider opening faces the camera body. When reversed, the hood still protects the lens but does not block stray light. Remember to flip it forward before shooting.
