Sigma 17-70 with 6" dome

One issue with this lens is that you need to use the 8" dome port for full zoom range.

I much prefer the smaller 6" domes which allow you to get closer to the subject and to the sand. They are also much more manageable on crowded dive boats.

So I tried it with the 6" dome (for the Nikon 18-55mm) and it works very well BUT you can't zoom longer than 50mm where the lens hits the inside of the dome.

  2. Yes it works well, not quite as sharp in the corners as the Sigma 17-70 but still worth using.

    You need to use a +2 or +4 dioptre to get close.
