Sigma 17-70 HSM in Ikelite

Here's my solution for fitting the zoom sleeve (that's the 5509.28 for fatter lenses)

4 tabs of sticky back velcro (hook side) stuck inside the sleeve provide enough grip on the lens zoom ring.

Thanks for the tip. The Sigma 17-70 is a great lens underwater.

Yes, I'm hoping it will be better than my 18-55 kit lens, which is still pretty good.
