The Mangroves are heavy, but one way or the other, you want your lights to last. That means batt power. The choice is a heavy batt pack on your housing or your tank... or self contained. I have cables, so I chose self-contained. Buoyancy can be easily compensated.

I bought the Mangroves several weeks ago and they are great. A lot of light for a 'sort of' competitive price. I have cables on my lights and housing, so these are great.
They are very well made. Stay away from cheap rubbish like the Bonica lights. Poor quality and bad service.

Hi Steve,

I am about to buy the a new set. Stil in big doubt between the new Genesis from Amphibico and the Bluefin with G10. Amph is much more my choice, but as I'm not making any money with it a bit over budget. So probably it is gonna be the BlueFin. That means I might be interested in purchasing a Fathom W90. If you have one for sale, make me an offer I can't refuse!
Nigel, I have also looked at new lights and have chosen for the Mangrove's 4L. They are amazing and give more than 4000 Lumen.

Hi Soren,

I'm also about to buy a new set, so after Drew's 'food for though' I contacted Aquatica and some photo / video pro’s for their opinion. Like you, before spending a bundle It is good to have done your homework!

This is what they say:

The CanonXF105, it is a very good camera, but difficult compare to the Sony FS100, since it has a much smaller sensor and fixed lens. As for the CODEC, it is a 4:2:2 MPEG2 @ 50mbps wrap into MXF file wrapper. The 4:2:2 might offer some advantage in multi-generation color reproduction, but the MPEG2 encoder is not as good as the AVCHD used by the Sony FS100, when there is a lot of motion in the picture. Were talking underwater video here so that means a lot of 'motion'!

The Nikon D800, is a very competitive solution, but use the right tool for the job, so all video guys would at this stage go for something like the FS100. It is a better choice as an all round video camera and will do the job under all conditions, Sony had as a long tradition of providing video cameras and have all the features required for almost all conditions of video shooting. A very responsive auto focus, WB selection and processing, better audio support, time code, etc.

The D800 will perform very well, in most conditions but ergonomic, and “live” video acquisition needs more attention.
Now the main difference for all those cameras is the 1080p60. One of them didn't like the 24P and 30p. Sometimes it works out because of the progressive scanning, but with fish and underwater creatures you may have a lot of judder. The 1080p60, provided by the FS100 gives a much crisper and clearer image, with a very fluid movement, it is not used for overcranking (slow motion), but because of the progressive frame. One of them used to shoot 1080i60 for long time, but will never do this again because of the availability of 1080P60. Note that some major film maker (James Cameron, and others) have already announced that their next film will be using an higher frame rate such as 48p or more. SMPTE is currently working in higher frame rate standard for film.

As for the lens issue, the Sony e-mount system is a very young system, already a lot of native lenses for various applications has been announced by Sony and others like Zeiss. Not all required lenses do exist but will be available over time.
In the case of the Genesis, adapters might be used, but will limit the use of the lens as for the aperture, and mechanical focus, Aquatica says it is in a “listen” mode” as for what will be required in the future.

Macro: Drew is right, the lager sensor (~35mm) and a 30mm macro lenses give near to 1:1 ratio, so a critter having a size of 5cm (~2”)
will almost fill the screen. Aquatica did test dives with the macro port, and they found out this is a bit limiting, but as soon as some equivalent lenses of 60mm or 105mm will become available in the future, or use them with an adapter ring, this problem is solved.

I have just repaired my 'old' EVO Pro, but hope to upgrade a.s.a.p. The problem is, there is a gap between big heavy pro cameras and small recreational cameras with housing. I hate those big bulky cameras and I'm a video guy, so for me there is no other option than the new Genesis.

Hope this is of any help.

Bon weekent as we say on Bonaire!

(Thnx to my Dutch video friend and Amphibico / Aquatica for taking the time to answer all my questions!)

Hi Soren,
I have been shooting UW video since 1995 and started with Hi8 and now shoot with Sony HDV. I live on Bonaire and a week ago I got the opportunity to test the FS100U in the new Amphibico / Genesis UW-housing. The Genesis is not on the market yet, so I was the very first to give it a go!

This is the config I used: Sony FS100U with 16mm E-mount lens; Amphibico / Aquatica Genesis housing with dome-port (compatible with all Aquatica ports!) ext. 16.9 Amphibico HD monitor; 2x Amphibico 10w. HID lights. (As this was a prototype, few things will change in the final production version.)

Location:
Salt Peer Bonaire.


Dive!:

I found the set very compact and well balanced under water, but the final version will get a slightly modified back cover, which should make balance / buoyancy even better. Compared to my prosumer Evo-Pro the kit is bigger, heavier on land, but underwater much more stable and better to handle. If you are used to carry around pro housings like they make for the Sony FX and Z cameras the Genesis is a blessing! It is much lighter and so much easier to handle.

The housing is equipped with a small window on top of the housing so you can use the cameras monitor. This will do the job, but I really loved the second external HD monitor on top of the housing, so you can shoot from all angles and always have a good view on one of the two. In both monitor you can see all camera settings which can all be adjusted with the buttons on left and right and housing.


Lens/port config was fisheye, which was new for me, but at the Salt Peer this was absolutely the best set-up. The FS100U is equipped with E-Mount lenses and the Genesis has the same ports as Aquatica. This gives you a lot of combination to choose from.

Verdict:

Pros: Amazing Pro camera with amazing picture quality in a tailor-made housing. A lot of lens / port options to choose from. Light and compact and well balanced.


Cons: If any, this is not a point and shoot consumer kit, but a pro camera with all important pro features in a pro housing. So, to take full advantage of its possibilities and great picture quality, get acquainted to the camera and learn how to use it in the housing. I guess not a big deal if you are an experienced (underwater) videographer.




Best from 'Divers Paradise' Bonaire.
