What size lens filter do I need for a Canon PowerShot SX430 IS? I have a 40.5mm UV filter, but it does not fit.
The PowerShot SX430 IS manual mentions neither filter thread size nor compatible filter adapters.
How certain are you that your camera has actual filter threads? Other Canon PowerShot SX# IS cameras do not have filter threads. Some have concentric rings to hold the lens cap in place. Some can use filters with a filter adapter.
If you are able to determine whether the lens cap is interchangeable between your camera and other PowerShot SX# IS models, the FA-DC67A filter adapter may also fit your camera.
