The Ikelite housing for the Sony RX-100

New camera & underwater housing: Sony RX100

My Sony DSC-TX5 has served me remarkably well, but after three years I was starting to itch for something with a bit more scope for manual control. The TX5 has an underwater mode: you switch it on, turn on the flash, and you’re good to go. It also has a rugged Sony-built housing that is almost neutrally buoyant with the camera inside, can be held and operated with one hand, and supports the addition of an external strobe (which I did). All these things make it incredibly user friendly and eminently suitable for a busy diver who might be doing other things (like grabbing onto other divers who are being wayward, or being a good buddy) and need both hands now and then.

I did a lot of reading and asking, and ended up settling on another Sony camera (my third, and the fourth for our family), the Sony DSC-RX100. It’s a tiny, pocket-sized camera that has many manual control options (aperture and shutter priority modes, manual and program mode, and some built in automatic modes) but isn’t a DSLR. It has received the most effusive reviews that I’ve ever read for an electronic device. Here’s Wired, and here’s the New York Times. Digital Photography Review also said nice things. It has a giant 20.2 megapixel sensor and a  fast Carl Zeiss lens capable of a magnificent 3.6x zoom. You can read up about those things elsewhere. It takes HD video, and you can shoot stills at the same time. What sold me on the camera was its reported excellent performance in low light environments (a feature of several of the Sony models I’ve owned), which I figured would make it excellent for Cape Town diving.

There are a couple of options for an underwater housing for the DSC-RX100, but unfortunately nothing made by Sony. I settled on the Ikelite housing because there’s a local Ikelite presence, and because it wasn’t insanely expensive. The housing unfortunately has the hydrodynamics of a house brick and mine needed its clips replaced after less than thirty dives, but the camera is nice enough that I was willing to put up with having a perspex sea-anchor attached to myself in order to get it into the water. Toting the housing around has also thrown my buoyancy for a loop, so I’m having to consciously adjust some things to get my air consumption back where it was in the good old days. (I’ve decided that my next camera will probably have a manufacturer-built housing, or I won’t buy it.)

Anyway. After much debate I also splurged on the Ikelite W-30 wide angle lens, which cost more than the housing and which has been my only recent Ikelite purchase that has worked flawlessly and hasn’t needed replacement or repair, probably because it has no electronic or mechanical parts. It’s magnificent. It screws onto the outside of the housing, and is a wet lens, which means that upon getting into the water you have to make sure that all the air gets out and water fills the space between the lens and the housing, otherwise you get a line across the middle of your photos. Same goes for when you get out of the water – the lens has to drain before you can use it on land.

My most sustained use of the camera so far has been on our Red Sea trip last October – you can see all the underwater photos on flickr in my wreck dives set, reef dives set, and night dives set. I am still using it mostly on the automatic and very simple manual settings, but I expect that playing with the camera on land (which I haven’t had time to do much of) will make me more confident with it underwater. The buttons on the housing are very hard to use with gloves on or cold fingers, and they are extremely close together, which means you have to learn what each one does (or carry a cheat sheet on dives) in order to change settings underwater. Despite these complaints, you can access all the camera’s controls via the housing, which is more than can be said for other housings.

The camera flash is immensely powerful. The housing comes with a diffuser (for photography without an external strobe) and a shield to completely block the flash from the front when the strobe is on. I use the latter when I attach my AF-35 Autoflash, which works like a charm. I have tried using the flash on the camera while underwater, but you have to be quite far away from your subject to avoid blowing out the image.

Apart from the clip issue on the housing, I’ve been very happy with the camera so far and am looking forward to doing some more underwater macro photography, since the DSC-RX100 focuses much closer than the DSC-TX5 (and indeed any other camera we own). I’m also enjoying its very easy to use video function, as you may have noticed from the proliferation of videos on the blog since April 2013! I’ve added a video light that has come in handy for photography on night dives, but that’s another story…
