  • Fantasea Line - a bit of diving history

    Howard Rosenstein was a Red Sea pioneer. He set up one of the first dive centres at Sharm el Sheikh and was responsible for promoting the Red Sea as a popular diving destination.  He even had a hand in the discovery of the wreck of the Dunraven at Beacon Rock. You can read that remarkable story in a chapter of Amazing Diving Stories.

    Next, he managed one of the first liveaboards in the area, Fantasea II. It was a top-end vessel aimed mainly at the rich American market so few British divers ever enjoyed her facilities but they often looked across the water enviously at her from the other somewhat primitive liveaboards that operated there back in the 'eighties. When Americans stopped going to that area thanks to political upheavals, he moved the vessel down to the Seychelles where he offered trips to the idyllic atoll of Aldabra. Just to give you an idea of the standard of quality of that vessel, the Duke of Westminster once chartered it as a private yacht for his family’s vacation. Eventually, Fantasea II got sold, renamed as Pelagian and continues to operate out of Wakatobi in Indonesia.

    But the Fantasea name lives on in a different venture started by Howard Rosenstein - Fantasea Line camera housings. Originally, Howard concentrated on supplying housings for compact Nikon cameras, cameras that did not prove so popular with divers in the UK. Now Fantasea Line produces a range of housings that suit the Sony RX range of cameras and some Canon compacts, and very good they are too. This includes an interesting option for the Canon G7X mk2.

    They are robustly made and offer full access to all the controls of the cameras, plus they accept any accessory wet-lenses, both wide-angle and macro, with a 67mm mount. At a time when the falling pound is making some Far Eastern alternatives very expensive, the Fantasea Line housings make a welcome addition to the range of housings for compact cameras available at Ocean Leisure Cameras, and at the moment they cost less than £500.

    Naturally, they allow for full synchronisation with up to two strobes (flashguns) via fibre-optic cables.  One thing that becomes quickly obvious is Howard Rosenstein’s long history with the diving industry because, unlike some housings designed by people who are not actually divers themselves, all the features have been well thought-out from the point-of-view of using them underwater. Howard is a diver and it shows!

    Especially interesting is the Fantasea Line housing for the Canon G9X. This is because this camera still provides the one-touch white-balance feature that made Canon compact cameras so popular with underwater photographers in the past. Alas, Canon has chosen to omit the simplicity of this feature on later models (although white-balancing is still available but less intuitive than it was).

    Although the Canon G9X is not the most recent compact camera to join Canon’s product line-up, we believe it to be one of the most useful entry-level cameras available for aspiring underwater photographers. You can find all the information about the housing for it by clicking here.

    If you are intending to upgrade or replace an older compact camera housing that might have seen better days, it’s comforting to know that your accessories such as strobes, mounting arms and lenses have a high degree of certainty of interfacing easily with a new Fantasea Line housing

  • New Compact Cameras for Underwater Photography

    I have to admit that during my twenty-one years with Diver Magazine as its Technical Editor, I was never much of a fan of compact cameras for underwater use. I found that generally speaking, their response time and underwater white-balancing left a lot to be desired. Even using a compact to record my children on a beach holiday in the Maldives left me feeling frustrated because the time-difference between pressing the shutter-release and recording the image left me with lots of pictures of vacant sand where the fast moving kids were no longer present. All that has changed. For example, the latest range of Canon compacts, starting with the S120 and peaking with the G7X, has a wide range of manual white-balancing specifications for in-camera jpegs that can be activated with a single press of one button once that option has been chosen when setting up the camera. Not only that but each takes a picture almost instantaneously the shutter release is pressed. They both also shoot RAW files with all the advantages those represent when it comes to home computer post-processing but these take a little longer to record onto the memory card in the camera than a conventional jpeg.

    Canon G7X
    The Canon S120 is the latest incarnation in a long-running range of little cameras that have long been popular with divers and costs only around £490 when bought as a package with its proprietary housing, but the Canon G7X has a much larger sensor meaning it can be used at higher light-sensitivity (ISO) settings without any electronic noise disfiguring the pictures. This means it gives excellent results by the light available at greater depths. With a polycarbonate Canon proprietary housing, expect to pay around £700 for it. The fly in that particular ointment was until recently the fact that the only submersible housing originally available for the G7X was one that did not accept ancillary lenses. Without a wide-angle wet lens fitted, one had to stand off the subject further than would otherwise be normal and the ensuing loss in quality thanks to the extra water it shot through lost the G7X any advantage over the S120 it might have had. recsea_rx1003_rearAgain, all that has changed with the advent of housings for the G7X by third-party manufacturers and the soon-to-arrive Inon adapter for the proprietary Canon housing. These can accept both wide-angle and macro lenses that fit directly to them without resorting to any adapter. Of course a bespoke precision machined aluminium housing such as that made by Nauticam at around £765 comes with a cost differential that puts it beyond the budget of many people but the neat little Recsea housing bridges the gap between that and the polycarbonate entry-level version. (Incidentally, there will soon be an additional fitting available at extra cost that will finally allow you to fit wet lenses to this too.) recsea_g7x_frontThe Recsea housing costs around £475 meaning this package of G7X and housing totals approximately £975. The housing is machined in Japan from durable corrosion-resistant POM and acrylic and as such is lightweight. POM is an engineering thermoplastic used in precision parts requiring high stiffness, low friction and excellent dimensional stability. In common with many other synthetic polymers, it is produced by different suppliers with slightly different formulas and sold under various names such as Delrin etc. The Recsea housing is rated to operate down to 50m deep and its clear acrylic back-plate is kept closed on to its water-tight sealing O-ring by a dial locking system. It offers full access to all the regular camera controls including the rotating front ring around the lens. You can use it in full Manual mode with access to both shutter-speed settings and lens apertures. A camera strobe diffuser and strobe mask with external strobe connection mount is included.recsea_g7x_open It weighs a mere 678g out of the water yet it is conveniently just negatively buoyant with camera installed when diving. Most importantly, the fixed front port of the Recsea housing has a 67mm thread that allows the user to fit a wide-angle or macro lens. The Inon UWL-S100 ZM80 (around £350) and the Subsee +10 Close-up lens (around £210) are popular examples. There is also a similarly neat Recsea housing available for the Sony RX100 mkIII camera that employs a sensor of almost identical specification to the Canon G7X. Both these cameras offer an interesting compact solution with picture quality approaching that of the more bulky and commensurately more expensive micro four-thirds cameras in their own submersible housings. recsea_g7x_rearI anticipate seeing a lot on the camera tables of dive boats and can recognise that the G7X and Recsea combination will appeal to those travelling Economy class by air without too much carry-on baggage allowance because it weighs so little and takes up so little space. You can buy both Canon cameras and housings at Ocean Leisure Cameras.
