MAINTENANCE Lens Protector The lens barrel has threads on the outside for mounting a commercially available lens protector (φ 62mm for LT260/LT220 and φ 72mm for LT240) to protect the lens from dirt, dust, scratches and damage. Note that both a lens protector and the supplied lens cap cannot be used at the same time. CAUTION: Use only transparent lens protectors designed for lens protection.
