Introduction
I was sent a Sealife Reefmaster DC500 Elite setup for testing. The kit arrived with the camera and housing, tray and strobe arm and the SL960D strobe and fiber optic sync cable. It also came with a SL970 wide angle lens, and lens dock for mounting the lens on the camera tray. The elite kit also comes with a nice soft case with die-cut foam inside. This setup is designed for extreme ease of setup and use - with everything included - so that a novice can put together the equipment and put it to good use right away. The camera also comes pre-installed with a number of underwater modes, for both flash and non-flash photography, which can eliminate much of the settings "guesswork" for a beginner.
Camera
The DC500 is an ultra-compact 5 megapixel camera designed for point and shoot photography. It has no specific manual controls for setting aperture and shutterspeed, instead using a number of preconfigured modes to set the aperture, shutterspeed, white balance, etc. The camera uses SD memory cards and a small rechargable battery. It has nicely designed controls which will be very familiar to compact camera users. As shown in the photos below, it is small and thin as compared to the Canon S400 and it has a big LCD display. The Sealife camera is very similar to the popular Canon SD model and probably uses the same sensor.

The DC500 also comes with a convient and easy to use docking station which can be used to connect the camera via USB cable to a computer, and to keep the camera's battery charged. I really like the docking station, as it can be left plugged into AC power and into the computer. The camera can be removed from the housing and inserted into the dock, and it can be charged and transfer photos without opening up the camera to remove the card or battery.

Housing System
The system consists of the housing, which can be used as a "stand-alone" or in combination with the camera tray, lens dock, strobe arm, and the strobe. When used for available light photography, the tiny DC500 setup is small enough to fit in the palm of your hand or tuck away into your BC pocket. When the whole setup is used, it can be folded up and is still small enough to clip to your BC when you need two hands for other tasks. The housing is hinged on the left and uses one closure on the right. One of the things I especially liked about the housing is the fact that all of the buttons are labelled. The housing is also rubberized, making it easy to grip and it just feels great in your hand. Inside the housing, there is a specially designed holder for the provided tube of silica dessicant beads, which keeps camera lens and the inside of the lens port from fogging up. The whole system is rated for use down to 200 feet.

The wide angle lens is compact, and can be fixed to the front of the housing using a bayonet for quick twist and lock mounting.
Strobe
The strobe used 4 AA rechargable batteries. These are inserted into a casette which snaps quickly into the strobe head which means that if a number of casettes are purchased, they can be filled with charged batteries for quick and easy change-outs on the diveboat. The strobe has a built-in slave sensor with an adjustment switch used to control the sensitivity of the slave function. The sensitivity can be adjusted so that the strobe isn't fired by the sun, or by other divers. A fiber optic sync cable is used to send light from the camera's internal flash up to the slave sensor on the strobe head. The cable comes with a mount that snaps onto the camera housing providing a good connection and also masking the cameras internal flash so that it does not create backscatter in the photographs. A rheostat switch on the back of the strobe head can be turned to adjust the strobe's power setting.

The strobe coverage is adequate for lighting up a large scene.
Image Quality
Because I wasn't able to take the Reefmaster diving, Bjorn Harms from Sealife was kind enough to send me a photo taken using the DC500 setup underwater using the strobe and wideangle lens. As can be expected from a consumer camera, there is some noise present in the photo, but images taken at the base ISO and with good lighting and exposure should look nice printed up to 8x10 size.

Conclusion
The Sealife Reefmaster DC500 setup is a well designed compact underwater entry-level system. When purchased as a package, the housing and strobe setup is easy to put together and use. The image quality is acceptable, and the built-in camera modes make the system adaptable and useful for both above and underwater photography. I would not hesitate to recommend this system to scuba-diving friends who have never used a camera underwater before, and to photographers who are not interested in comparing camera specifications and making complex purchasing decisions.

Comment(s):looks like sealife has come a long way since the first got into the digital market ... i am actually impressed where as i was appalled at their first model.

Posted by PeterCatchpole on 01/15 at 02:37 AMConsidering this camera is listed at $430 bucks on Ebay with another $240 for the 960D, I gave it a hard look when I was fishing for a starter camera. I still might end up buying it as a 2nd camera.
Posted by ce4jesus on 01/15 at 08:40 AMI purchased and used this system for a week-long dive at Wakatobi Dive Resort in Indonesia. While I agree with most of the review above, I have a couple of issues.
1) Battery Life—I found I the battery not up to expectation, discharging after about 35-40 photos.
2) Strobe connection—The fiber cable for the strobe was problematic, working on the surface, but sometimes not underwater. I had to shoot on slave mode, which restricted how I could point the light.A friend using the same camera had similar issues. having said this, I found camera easy to use and image quality quite good, both on land and underwater.

Posted by DavidWarshaw on 01/16 at 09:25 AMThanks for the write-up. And David, thanks for the additional comments. I’m 99% certain I’m going to buy this camera with my tax refund, and it’s nice to know that my money isn’t going to waste.
Posted by WillyVolk on 01/16 at 11:38 AMWhen I received my DC500 (stupidly purchased online) I was amazed at the clutter of bits and pieces in the box. I think that this camera is so small that it will be impossible to repair. I find the external buttons clunky on the housing. But the buttons on the actual camera fiddly and far too small for my male fingers. The shutter delay is appallingly slow. I thought my Fuji Finepix S5000 was slow (and have deleted many spoilt images due to the subject moving just when I’d pressed the button - but the DC500 is the slowest ever - it takes a full second to decide to capture an image. How on earth can it be used in a marine environment where EVERYTHING is moving. On land (sans housing) I found the picture quality far inferior to the Finepix - being blurred and ‘grainy.’ So much so that any print greater than the standard 4 x 5 will be useless. Also I am MOST upset that I have to use the camera itself to charge any spare batteries. Why can’t they make a dedicated charging unit? How on earth Time Mag. voted it as the ‘best invention for 2005’ beats me.
Further issues with the DC500.
Searched the UK Digital Photography mags. for ‘Sealife’ - but nothing, zero, zilch, sfa. Plenty about Fuji, Pentax, Nikon, etc., etc., but nout about Sealife cameras. Also searched UK Dive Mags - but nout there either. Then I discovered in tiny print on the camera casing the dreaded ‘Made in China.’ Its hardly a world class product commensurate with those well established German or Japanese firms then. Wonder what the Chinese sweat shop workers get paid for manufacturing something sold at £300+. The quality is so high even the sticky label on the front of the camera is stuck on crooked. Goodness knows what the quality of the lense(s) and innards are like. Then there is the issue of the underwater housing. TWO MAIN DESIGN FAULTS. 1/ The fastening clasp is proud of the case (next to a whole bunch of buttons)which would make it VERY easy to inadvertantly open the housing underwater. One such accident and £300+ camera becomes a write off to say nothing of £50+ worth of chip and irreplaceable images. 2/ The operating spring-loaded buttons themselves are loose and wobble meaning that their rods pass through the casing but do not appear to be adequately sealed. At present I would not even want to immerse the camera in one foot of water in the bath, let along 200 feet in the ocean. I’ve yet to immerse the housing with blue tissue paper inside to measure its waterproofing (a tip from a dive mag.). I’ll report back when I’ve tested it further. Generally it appears that the internal DC500 camera is just a bog standard point and shoot box - which even the Digital Camera Press (in the UK) can’t be bothered to review.
Oh yes, and the Pro bundle didn’t even come with any silca-gel - this is an optional extra!!!
Posted by CJB on 01/23 at 06:04 AMI received some feedback from Sealife concerning a mistake I made in my review:
“I noticed under the Strobe section, you mention that there is a slave sensor adjustment switch. I believe you are referring to the pre-flash cancellation switch. The slave sensor sensitivity can not be adjusted. The pre-flash cancellation feature allows the Digital Flash to synchronize with practically all other digital camera brands. There are 5 settings, from “0” to “4”, which represents the number of pre-flashes the digital camera uses.”
Sorry for the confusion and thank you to Sealife for following up with a correction.
