Hi guys

I was pretty fortunate this year for the holidays and I recieved a Cannon T3i from santa. Ive used only little point and shoots (dc600, coolpixs l24) so most of this is all new to me.

So far i have been looking at the Sea & Sea RDX housing with the tokina fisheye lense. the big issue i see now is backscatter has a used optical dome port for a fairly good price but its the acrylic not the glass. Does anyone have expience with the acrylic or have any recommendations?

Thanks
Jon
