This basic Outex installation shows how to install the LCD housing/cover, front optics to your lens, and the rear LCD adaptor and LCD viewfinder on the camera. This basic installation will get you started, and is ideal for basic Outex kit use. In addition to the trapped air test mentioned in this video, we recommend doing the shallow water test where you look for air bubbles BEFORE utilizing Outex in real world situations. You should always do the trapped air and air bubble tests every time you intend to use Outex in underwater conditions, specially if you have tripod or cable adaptors, flash kits, etc. Please consult additional, specific installation videos for each of those on our INSTALLATION page at Outex.com.
