waja 0 Posted May 31, 2022 Has anyone used an Aquatica Housing for shooting a Canon EF 16-35mm f/2.8 L II lens? I am trying to determine which extension to use. The Canon lens chart shows Canon Lens Zoom Focus Extension Canon EF 16-35mm f/2.8 L II USM 48708 AF only 48457 Canon EF 16-35mm f/2.8 L II USM *(2) 48708 19064 48464*(2) The problem I have is that the 48457 is 54.5mm and the 48464 is 74.5mm. There is a 48459 at 74.5mm. Thanks for any information. -Rick Share this post Link to post Share on other sites
OMorissette 9 Posted May 31, 2022 I suggest to contact directly Aquatica support. I wanted to use a lens that was no on the chart and contacted them, they determined the best extension for me! Share this post Link to post Share on other sites
ChrisRoss 150 Posted June 1, 2022 The second option is if you want a manual focus gear and the footnote says that the 48464 extension is fitted with a MF gear. I suspect they don't have an extension that is 54.5mm long and also has a focus gear/knob. Aquatica should be able to clarify but I expect if don't need a MG control on the extension that the 48457 extension will be the one. Share this post Link to post Share on other sites
