Hello Giles… As far as I know from Uwe (the manufacturer) there are two versions of this housing. One is the old type for the D30 which is not produced anymore. This is the same type which is used by Eric Cheng and Jim Watt. It was also able to house the D60, but missing one or two controls for the camera. This is also the version shown on all the pictures we have.
The new version is especially designed for the D60 and features some slight changes, providing all controls underwater. But I have to admit that this is not a users experience - just what I was told.
