Hi, Im looking at putting my S1Rii in a Nauticam housing. I want to shoot Video and stills. 60/40 Has anyone used a the Lumix 100mm F2.8 with Macro Port 27? The Sigma 105mm doesn't support manual focus in the housing or MFO-3 based on Port Chart. I want to Manual focus as well as Auto, for super macro video It comes with Bayonet Mount only (Macro Port 27), but port chart doesn't support M67 (I have Dual Flip and Diopters and MFO-3, ) - Don't want Bayonet Mount! Was going to adapt my EF lens etc, but adapting is hit and miss so not going that path. Anyone with Panasonic experience would be appreciated. Regards Hugh
