Fasando 3 Posted July 6, 2012 Are uv filters any good underwater? or should i not bother getting it underwater? Share this post Link to post Share on other sites
bvanant 179 Posted July 6, 2012 No need for one underwater at all. I question the need for one above water as well, I always cringe at the idea of putting a $40 filter on the front of a $800 lens. Bill Share this post Link to post Share on other sites

bvanant 179 Posted July 6, 2012 That's why I use one topside Ouch, I try hard not to drop my camera, and topside I mostly keep it around my neck, not that I shoot much outside the studio anymore. Bill Share this post Link to post Share on other sites
blaisedouros 4 Posted July 6, 2012 Luckily that's not my gear, it's a fellow whose blog I follow. I get out hiking a lot shooting nature and wildlife stuff, so sometimes slipping and falling or some other unforeseen event is inevitable. I sacrifice a very small degree of sharpness to the gods of paranoia... Share this post Link to post Share on other sites
tdpriest 115 Posted July 30, 2012 I always cringe at the idea of putting a $40 filter on the front of a $800 lens. I always cringe at the idea of not putting a $40 filter on the front of a $800 lens (actually an $80 filter and a $1200 dollar lens, but who's counting?). Underwater, however, it's just not needed as the front element is protected by the port. Tim Share this post Link to post Share on other sites
bvanant 179 Posted July 31, 2012 (edited) I guess I am in the poor minority here, not having any $1200 lenses and in thinking that filters degrade images. I think this is one of the minor things that people debate all the time but I have seen enough (not underwater) filter flare to think of filters like lenscaps, take them off before you take a picture. By the way, most UV filters don't filter much UV and you current lens will pass only a teeny tiny amount of UV anyway, but as Dr. Tim says, underwater it isn't needed anyway.

sideshow_Gary 1 Posted October 31, 2012 we had a mix up with our lenses and we took a UV filter in the UW housing, but it pushed against the glass of the housing when focusing so it wouldn't allow us to focus on close or far away subjects.. very annoying!

3ricj 0 Posted November 14, 2012 Depends on what specific wavelength of UV ya'll are talking about, but it is readily absorbed by the water. http://th.physik.uni-frankfurt.de/~scherer/Blogging/ColourWater/absorption.png Share this post Link to post Share on other sites
