Mark K 5 Posted April 19, 2013 I have tested and used this for some time http://www.ebay.com/itm/XPRO-F500-67mm-Close-Up-Lens-Macro-lens-Super-Macro-Conversion-Lens-/280874520769?pt=Camera_Filters&hash=item41656d10c1 mostly using the 49mm on my Nex camera lenses.

bvanant 190 Posted April 21, 2013 I don't know if it will fit in the housing, but if it does then it will work pretty much the same UW as on land. If you mean putting it on the outside of the housing then you will get much less magnification with it if it is wet. Bill Share this post Link to post Share on other sites
Lwang 0 Posted November 18, 2015 Did you try this dry diopter underwater? As a wet lens? I would think it being a achromatic double lens, water seeping into places becomes an issue, especially between the space between the lenses. I would think a single lens, even with its inferior image quality, would last longer as a wet lens. Share this post Link to post Share on other sites
