of course it's focus gear - it was my mistake it's impossible to make zoom gear for fixed focal lenses

Zoom gear for Sigma 50 mm is Aquatica#18701 https://www.bhphotovideo.com/c/product/352604-REG/Aquatica_18701_Focus_Gear_for_Sigma.html

I made a mistake - it's not 6" dome port - it's about 21 cm diameter, so it will be 8 inch dome.

still available?

Lumix 7-14 still available?

I'm completing M43 setup (OM-D M5 mk 1/Nauticam/6" dome) and looking for a lens. Anybody tried Lumix 7-14 and Lumix fisheye 8 mm? I know main differences: angle of view, geomethry etc. but looking for info about sharpness and overall image quality.

Does anybody know this housing? I bought it on eBay and seller didn't know so much "I got them on estate sale" he said. So, I'm looking for any information - model name, max depth etc. I sent ask to Inon but no one answered. There is Inon brand on the dome and sticker "PROMO. S U/W HOUSING GF2 NO0008" inside. I got two front parts of housing - one with dome and one with flat port for macro. Maybe anyone have seen similar housing and wille give me some information. Big thanks for any help:)

For RX100 there are two quite cheap housings working with flash+diffuser: - Sony MPK-URX100A - genuine Sony, max depth 40 m - SeaFrogs RX100 (I-IV) - max depth 60 m (!) with really good quality and ergonomics
