I'm looking for experiences from others who have used the UCL-67 with a housed DSLR...
I have 60mm and 85mm Nikon lenses with an old D90. I spent a little time playing with both lenses plus the UCL-67 on my kitchen table and I appear to get a much greater magnification of the subject when using the 85mm lens. The magnification when used with my 60mm lens is little better than my old Subsee +5 diopter!
I've not done as much comparative testing in water but it's starting to feel like the UCL-67 on my 60mm is not that good.
BTW: I'm shooting mainly in the UK so I don't want a very big working distance between lens and subject; which is why I don't own a 105.
The UCL-67 just doesn't appear to be the +15 diopter it is advertised to be.
