Fantasea is Polycarbonate, as opposed to Sea & Sea and Nauticam which are Aluminum. There is a big difference in their feel and of course the price, but if you dive once or twice a year, you may not need the Aluminum housing and you can use that price difference for a strobe or a wide angle lens. All in all, Fantasea is a brilliant housing.


If you are considering the Sea & Sea YS-01 vs the YS-D1, then yes, the upgrade is well worth the extra $270, The YS-D1 is more powerful, more versatile and more accurate. 2 Strobes are much better than one but that comes at a price so this is your call to make.


Read our post about Flex Arms vs Ball & Joints HERE.

I shoot with Flex arms, many people prefer ball and joints. Frankly, for Macro the only thing that matters is that flex arms make a noise when moved and that can scare things like Goby’s away.

Macro Lens

With the RX100 III, you must have a macro lens for good macro so take that into account.

The Nauticam CMC is a great option for compact cameras and will work with any camera/housing with a 67mm thread. You will need a 55-67 step up ring.

Another excellent option is the Fantasea +8 Sharpeye.

If you want to do some off-camera lights, you need at least 2 powerful video lights. I would prefer SOLA’s as their angle is not as wide as others and then you get the beam effect in the shot , take a look at the SOLA 2100 Spot/Flood.

The 2000 Lument Flood SOLA‘s are a very good deal, going for only $449 each.

Here’s our recommendation:

Fantasea FRX100III with dual YS-D1 Package. – $2,099 (Optional Upgrade to Ball and Joint arms +$300)
2 x SOLA 2000 Flood Video Lights – $898
Macro Lens – Fantasea +8 SharpEye$199 (Optional Upgrade to CMC, +$121, Step Up ring needed)

Total System Cost – $3,196 – $3617

Whichever you choose, we are here to help. Contact our experts so we can help you choose the right system for your needs!
