The risk of flooding your camera, ruining your photo-shoot and vacation is much higher with a non tested lens. Pressure tested lens is guaranteed to be hassle free (unless photographer did something wrong). If internal O-rings fail, lens and your camera are done for. That is why I show you in the last photos what can happen.If you intend to never dive with the camera, and only use it in wet condition such as Kayaking, Surfing, rainy weather or waterfall shoots... Etc, then you are ok without a pressure tested lens as long as the lens mount O-ring is present. But as soon as it goes underwater, weak or worn out O-rings will flood the camera and you are back to zero. Most floodings happen the first 10 ft / 3m from the surface. The water pressure is enough to force itself pass the O-ring.
