If this camera looks familiar, it’s because it’s the Ricoh Caplio GX100 dressed up with a Sea & Sea badge and slight modifications. It’s called the Sea & Sea 1G . The underwater housing is the Sea & Sea DX-1G and is good down to a depth of 50 m.
Sea & Sea sells the housing and camera as a set, and together they cost SGD$1450 (about USD$1000) including GST here in Singapore. The Ricoh GX100 costs SGD$824/USD$569 (including GST).
The thing is that Sea & Sea won’t sell you the housing on its own. Which means I’ll need to buy the Sea & Sea 1G version of the GX100 if I want the housing.
