Hi,
Newbie here (both in terms of scuba and underwater photography) with Oly EM-5 and a Meikon case that has only been tested in my bathtub.
I'm trying to decide whether it's worth to spend on an external filter that's attached to outside of your case (i.e. http://www.intova.net/ifred-red-filter/) or just use the one that I already have (normal round red filter, attached directly to the lens). I'm not trying to spend alot of money since I'm just a beginner.
Any thoughts? Thanks.
