Really weird question, but wanted to confirm the weight of the 140mm nauticam glass dome (https://www.nauticam.com/collections/n120-ports/products/n120-140mm-optical-glass-fisheye-port-with-removable-shade ) this would be for the canon 8-15mm fisheye lens. On the website it says 1.45kg, but that doesn't seem correct cause of 2 reasons:
1. WWL is around 1.3kg, so that would mean a dome port is heavier than a proper water contact optic?

2. In @Interceptor121 blog, I think i remember seeing something like 600grams in one of the post, but can't seem to confirm that number anywhere else

 

All help appreciated! Thanks

Mine is 0.76 KG for the port (with cover). And 1.2KG when it is in the carry case it comes with. 

Thank you! Much appreciated. Not sure someone can let Nauticam know their website probably should be updated 😅 ruled out the dome port cause of the massive 1.45kg weight haha

630 grams as in my blog

Thanks you @Interceptor121 for confirming!
