Oh thats a nice camera :), Yep they do make and they have one for D5200, Ikelite I mean. I went for Ikelite cause it was the cheapest of the housings, the only disadvantage of it is that its heavier on land as compared to other housings which are lighter but very expensive to buy. As of now I have been to the Andaman and Lakshadweep Islands in India and to Maldives, I mostly prefer warm waters with great visibility cause for Underwater photography You need good visibility. I want to dive in Indonesia, Cayman Islands, Bonair, Great barrier reef and the Red Sea. What about You ? Where would You like to dive ? Also where have You gone diving till now ?
I Am a freelance Wildlife photographer too :), But recently have decided to completely concentrate on underwater photography, Yes good equipment is pricey, thats true, I use a Nikon D300 in Ikelite housing and use 2 strobes of the same brand, Its a great feeling to capture what You see underwater :) Which camera are You using now for doing land photography ?
