Thanks Lionfish, let me try this using the camera of my smart phone on the view finder, if this is the case, probably the least expensive way with best result! Such a good suggestion and idea! Cheers!

Hi Phil, thanks for your reply. However, I am not sure why I haven't got your PM. I've also found another source here in Asia for the zoom gear.. pls. let me check and if I can't make it, will definitely reach you and ask for your help again. CHeers

Hi Phil, may I know the N-100 to N120 35.5mm port adapter with zoom, is the Nauticam serial number #37303? It's with Zoom and focus knot right? I have the 16-35 lens already. I am interesting in the zoom gear and also the adapter. From what Nauticam's recommendation. It seems that if I use this 1635 lens, I need 1> N100-N120 adapter, 2> 180mm Dome and 3> zoom gear. if the extension ring 21150 required? I actually tried to use n100_n120 knot adapter + 180mm glass dome and it's working (except I don't have zoom gear that I can't adjust). So I doubt if that extension ring 50 is indeed required. Thanks for your help!

mt-m and Phil, many thanks for your advice and sharing. Pls. let me study again carefully on your advice and information. Much appreciated! Definitely will reach you both if I find the need of getting extra equipment! Thanks and have a nice weekend!

Hi all, Greetings. I am new here, nice to meet you all! Hope I ask the question at right group. I am using SONY A7R2 with Nauticam Housing. I've been doing Macro for past months and was about to start with Wide / Fisheye photo taking. After searching around, I decided to go for an economic solution using Sigma 15mm Fisheye lens. I know that Metabone adapter is necessary and seems it's been working well with Sigma and Canon 8-15mm fisheye lens. At the same time, I also found that Sigma MC-11 adapter has been widely discussed and it's around half the price of Metabone but performing the same. Therefore I went to this option (Sigma 15mm Fisheye + Sigma MC-11 EF adapter) It's been working great on land and I was fully confident before I jumped into water. Since my first time, I found there is problem.... I couldn't press my shutter properly and the lens couldn't focus at all (forgot to mention I've updated to the latest firmware for both my SONY camera and Sigma Adapter, I also test it working perfectly above surface without housing). I had to power cycle my camera underwater to try if it could help... however, the result is negative I found everytime I took it out from my Nauticam housing, it was like hang status, then I tried to toggle the switch of the lens from Auto to Manual then back to Auto and it works again. I thought this maybe adapter issue, but later, I found it's the housing vacuum environment related. I am using a Nauticam housing as mentioned before plus a N100-N120 adapter and 180mm DOME (it's not big enough, I see the black shadow). I found that whenever I try to pump the air out to make the housing vacuum (green light), the camera may work sometimes... if I get a few more pump after the vacuum light turned to green, I couldn't focus at all, and also can't press the shutter to shoot properly. Since I've not tried Metabone, may I know if there is any user can share their experience either using 1) Sigma MC-11 or 2) Metabone adapter? If you have similar problem, pls. can you share if you have any solution? Thanks for reading and your help in advance! Have a nice day!

Greetings! i am new to wetpixel and also underwater photography. I am from Hong Kong and I am using SONY A7R2 with Nauticam housing. Currently I've got 90mm Macro lens for macro critters Nice to meet you all!
