This is a lens filter that can be attached to a single-lens reflex camera. The light transmittance is 95% or more, and it does not affect the image quality! We recommend using it to protect your expensive lens from scratches and dirt. Even if you are careful, scratches can occur from other causes. Especially when used outdoors, the presence of a lens cap or filter provides peace of mind. If the lens filter is too expensive, you may become overly cautious, so you might consider it a consumable item. Other sizes are here ↓ #Lint's Lens Filter
