Fast answer: On the Canon 77D, “silent shooting” is a menu option, and the quietest behavior is commonly in Live View. Enable it in the Shooting menus, then test once in Live View and once through the viewfinder so you know what changes on your body.
Canon Silent Shooting Guide: What silent shooting does, tradeoffs, and common problems.
Do this (5 steps)
- Set a normal photo mode (start with Av or P).
- Press MENU.
- Open the Shooting (red camera) tab and look for: Silent shooting, Silent shutter, or Shutter mode.
- Set it to Enable (or choose Electronic if that is the wording).
- Take one test shot in Live View and one through the viewfinder to confirm how your 77D behaves in each mode.
Direct answer
Enable Silent shooting (or the equivalent electronic shutter option) in the Shooting menus. If you cannot find it, turn on Live View and check again, some models only expose “silent” behavior there.
Quick note (mode-dependent behavior)
On some Canon DSLRs, the most noticeable “silent” behavior applies in Live View rather than through the optical viewfinder. If it is not fully quiet through the viewfinder, that is normal.
FAQ / troubleshooting
Why is it greyed out?
- Remove any flash/trigger from the hot shoe (silent modes often conflict with flash).
- Switch back to a normal shooting mode (avoid Bulb/special modes while testing).
- Enable Live View and re-check the menu.
The shutter still clicks
- Some mechanical sound can remain (mirror/aperture/IS). The goal is reduced actuation noise, not always total silence.
