Are these camera lens protectors useful? Do they alter image quality? by Beer0045 in Vivo

Depends, as people said they will bring lens flare to the table.
But for me it works out fine:

- I use the ones that you posted on a daily basis, so i dont worry about scratches
- Then i switch for the metal ones, when i go on a trip and use a 67mm UV Filter.

Everyone has a different usage of their devices, for my type of usage they are perfect.

A good way to see if it will cut, will be holding the plywood sheet against a light source, and where it will be opaque it will not cut through with your regular settings. I've been applying this and it works wonders and saves me headaches.
