I'm making photo's and video's for about 3 years know using my Olypus PEn e-pl6 in a pt-ep10 underwater case. I started with kit lens since it had a gear ring which let me use the zoom function.
This is a MFT camera and since I use a Panasonic GH5 for al my "dry land" photo and video I use its 12-35 lens on the PEN in the same case. Because of quality of this lens I saw improvement in quality of both photo and video. So the next logical step is to take my GH5 below the surface. But this means I have to spent "some" money. I really can use some help on what to choose and if I should go for new (and therefore expensive housing) or should I go for used (but where to find an affordable but also trusted vendor)
Al input is welcome.
