Sanity check (FIX S95 port conversion to INON AD)

[Lewis88 13]

Hoping someone here might have some experience in what I'm thinking about doing before I purchase anything. 

I have a Canon S95 in a Fisheye/FIX housing, FIX UWL-04 fisheye lens, dual YS-110a's, and SOLA 500 (see pic here: https://imgur.com/a/Sn7UioM).  I've been looking to add a close up lens to my setup, and am looking at the INON UCL165. I also would like to convert from the M52 mount to a bayonet mount due to threaded mounts being a pain underwater.

 

I am looking at purchasing the following:

- Housing conversion - M52 to AD adapter: http://www.divervision.com/deeproof-ad-lens-adapter-for-m52-thread-housings-ADF-M52.html?search=ADF-M52

- Wide angle conversion - UWL-04 into M52->M67 step up ring into M67 to AD adapter http://www.divervision.com/10bar-m67-thread-adapter-for-inon-ad-mount-base-adm-f67?search=ADM-F67

- INON UCL-156AD close up lens

- 2x AD lens holders 

 

In theory, all of this should work, but I'm unsure if I'm missing something regarding lens interference, vignetting, etc, especially with the wide angle lens.

 

Anyone do something similar or have any feedback on my plan?

Nodal points are rarely mentioned, but are critical. Pictures work well.

I have no idea about how to even start calculating the nodal point of my current setup, and how it would change if I were to move to AD mount. Way above my knowledge level, and I lack significant information about the stackup of the all the adapters.

The adapter to convert M67 to AD is not meant for wide angle lens and would significantly impair the image quality
I think you need to resort to an M67 close up lens or abandon the idea of wide and macro on the same lens unless you replace your wide angle lens with an Inon UWL-10028AD with dome that will work very well with your set up. Then you add an M67-ADF adapter an Inon AD28 to AD spacer and you can then use the UCL-165AD
Nodal point is not a consideration for a wet lens as this is not a dry dome

That was my biggest concern about how the adapters would effect my UWL-04.  Does it basically put too much water between the stock port and the rear of the wide lens? is it something that zooming in slightly could solve?

I’d like to add a close up lens but I don’t want to replace my wide lens at this point. System is 8 years old and will likely get replaced in the next 2 so I’m hoping to add something cheaply and if I can move away from the thread mount, I’d like to. 
 

also have been considering the sea life super macro lens since it’s native M52, but it’s hard to find reviews for.

Better to get a step up ring for a close up lens and leave the wide angle as is

Hi Lewis

If you are thinking in replace/upgrade your system in 2 years, you should consider what you are going to get and have it in mind for anything you buy now, to protect your investment.

Next system will likely be mirror less without wet lenses so it’s a stopgap for now

Any experience with the recsea 52mm flip lenses? Either the 2 or 3 lens?

 

trying to figure out the best option for macro

The WA you won’t use, but a macro lens is usable.

With that in mind, if you want now a macro lens, I wold stick to a M67 one. For your later system it is easy to use with a flip adapter, solving the issue of easiness of on/off underwater.

You're likely right, I would use it on a flip holder with a macro lens. 

 

Well, since the bayonet mount is out, I'm now looking at the divervision magnetic mounting system. http://www.divervision.com/howshot-m67-magnetic-lens-mount-MG-M67.html?search=magnetic

 

This setup would be:

M52 lens port -> M52 to M67 step up ring -> M67 magnetic lens mount -> lens (either M67 native close up, or UWL-04 on a M67 to M52 step down ring).

Any issues with this and the UWL-04? Can't find a ton of reviews of this setup, but it looks like it would get me the quick connect capability of the bayonet mount without hampering image quality? 

My only concern is lens security (not sure how secure these magnets actually are).
