giz1968 0 Posted April 29, 2011 hi all does anyone know if its possible to use a (red) filter in conjunction with inon ad lenses?,i mean specifacally on the outside of the housing,so the filter can be added towards the end of the dive in the shallower depths. i suspect the answer is no,but ya gotta ask. any ideas would be great. jason lee Share this post Link to post Share on other sites
