Hoya filter close up filter for macro photopraphy

[timz]

Hi everyone,

I'm currently using Canon S100 with a Meikon housing. Love the camera and everything works fine.

However, I would like to take some picture of really small stuff such as cleaning shrimps, skeleton shrimps, garden eel, nudibranch and some other macro marine.

Is there a problem with Hoya close up filter +10? Actually I have a few pcs of Hoya macro close up filters lying around since i do not have anymore lens that uses 67mm filters. Just wonder if it could be used underwater as well.

If there is any precaution on using it, please advise me.

Btw, I also have a Hoya Orange G filter i used for my black and white pucturez back then. Not sure if it'll help and produce similar effect as other underwater red filter during videography or photography.

Currently, I only have the following

Canon S100 + meikon housing
Tray
Archon d10u torch on a goose neck mounted on the hotshoe adapter on the casing which isn't connected to the camera.

Thank u in advance

Single element diopters for land use will have issues of chromatic aberration in addition to rusting

try it out in your bathtub. take pics of a ruler with and without the lens.

but be prepared for some issues
- the hoya +10 will lose most of its power underwater as it is an air-to-air diopter and not a water-to-water wet diopter. it is possible you will not notice any magnification depending upon the cameras zoom and minimum focus distance
- the metal ring may rust on you
- you may notice image distortion
- you may notice color distortion

the orange filter may not be waterproof and the orange may wash off? and no it is not a red filter, it will not work as a red filter.

Thanks for the comments. I tend to forget the water density over air.

Any affordable 67mm filter thread lens for macro that you recommend??

Look for Inon ucl-165 or dyron +7
