Currently using an Olympus PEN E-PL1 with 14-42mm lens for the underwater shots and I got myself an Olympus OM-D E-M1 with 12-40mm F2.8 lens as Christmas present! Besides these – the iPhone 6 camera is not too bad and very, very portable.
So I did a huge upgrade, going from the Olympus Pen E-PL1 with Olympus housing to the Olympus OM-D E-M1 with 12-40mm PRO and 12-50mm lens, the second mainly to be used underwater as it also has great macro capabilities that makes it an allrounder for when I can’t choose. Of course, a Fisheye with dome port and a real macro lens are high on the list. For lighting underwater I have an INON Z240 strobe. For my photography until now, I can still manage with one. However, when I get the Fisheye, I’ll have to get the second! (ps: I finally got réal strobe-arms now, picture update to follow!)
Most of the video footage shot until February 2017 is done with a GoPro Hero 3+ Silver. It really was a great camera, but it disappeared from my collection. But! The great news is that I now got the new GoPro Hero5 Black as a present for my 30th birthday!
