#324589 Kenko 1.4 TC...but which one!

Posted by Gudge on 16 January 2013 - 05:09 PM

While I do use a Nauticam housing I am using Subal mount dome ports/extensions with a Nauticam/Subal converter.  Therefore, I can't answer your question directly based on what I'm using.  The Teleplus Pro 300 is 19mm long so you'll need an extension ring as close to 19mm as possible.  I add a Subal 18mm extension ring when using the teleconverter but in your case it looks like the best fit is the Nauticam 20mm extension ring:

18520 Compact Port Extension 20

Edit:  Correct part is Extension Ring 20 #21120

You will also need a new zoom gear for the combination:

Took this in Lembeh about three years ago, Steve's and Adam's advice is basically what I did.

#315699 Will it work?

While those lenses may fit inside the dome and work without and extension ring the results will be less than satisfactory (distortion, soft edges etc) because the entrance pupil of the lens will not be aligned with the centre of the dome.  There's more information here:

#312804 "Eye level" of Persian Carpet Flatworm

Flatworms do have a "head" (for want of a better word) but it is not clearly visible all the time.  Here's a couple of shots showing the "head", it's the inverted V shaped bit at the front end.  Use this in your composition as you would rhinphores with nudibranchs:
