In Topic: Dome vs Wide Angle explain?

12 November 2014 - 11:59 AM

yes it will work fine and very practical with the Nauticam diopter adapter for the 4" dome port,,,  

If I use this lens I now use it with the dome port and the very practical diopter adaptor for this port.

Also because my Macro button on the lens has stopped working !  :((

The 12-50mm lens will fit in the 4 inch semidome port from Nauticam (for the 9-18mm lens) but seems not to be able to focus between about 35-50mm.  It will give you more field of view than the flat port you currently have but can only be used at the wide end of the lens.

 

I have used it a few times in this configuration but had no problems whatsoever except some chromatic aberrations that can be cleaned afterward.  I found it more useful than behind the expensive and dedicated flat dome from Nauticam,,,

dont have a pool but the sea :crazy: ...  unfortunately i just started the dive season and have little time for now...  but will do more testing eventually.

 

Anyway Alex M.  did a test in the pool which showed both in the pool

You can see the depth of field in the back of the pool improved by using the 4.33" but the CF of the 3.5" is fantastic...Corner sharpness seems Ok in all of my shots also.

I use the 3.5" dome with the NA-EM5 housing and I have vignetting with the 8mm Pana in 4:3 aspect ratio.

I have both and for CFWA the 3.5" is fantastic.  The size is also a big plus compared to the 4.33".  I would use the 4.33 only for over/under shooting.
