Lots of photographers out there who initially just tried water photography have become hooked with the scenery. Beginners who used compact camera during the first dives have now moved to DSRLR cameras that passed a digitalkamera test. Sure you might have the DSLR camera, the lenses and housing that are perfect for your new camera. Aside from that, there are actually a few more accessories that you’ll need when capturing the perfect shot underwater.
The camera housing won’t be enough to take your camera underwater, what you also need is a quality lens port. The lens port would be the tube that goes in front of the lens, it’s what covers the lens and completes the entire housing. Macro lenses typically use flat ports, but for wide angles go for the dome port; ports are usually made of glass and acrylic. Glass lens are optically better and pricier while acrylic weighs less and are easier to fix when scratched. Manufacturers have numerous types of ports and even more extensions that fit perfectly on to the lens. Extension rings are basically aluminum rings which extends the port even further from the housing.
Arm System and Mounting Options
For mounting underwater lighting, there are two main options namely the ball-joint arms and flex arms. The former is popular with DSLRs while the latter is for compact cameras. Ball-joint arms are available in various sizes and types, depending on the manufacturer; all of them are essentially strong and lightweight with a 1” ball found on the end. All of these are connected altogether with the help of clamps which you twist in order to fasten the grip. Take note, when taking macro shots you have to keep the strobes close, but keep them far if you’re aiming for a wider angle.
