Hi....doing some upgrades and considering expanding use cases for my existing Nikon D300/S&S MDX-D300 setup and need some confirmation of port/extension combos before I start spending money.

I have Nikon 10.5mm and Nikon 12-24mm lenses. I have the S&S NX Fisheye Dome port (acrylic, large dome, NOT compact)

a) CFWA or WA Macro

I would like to put a teleconverter behind the 10.5mm to try some of really cool "macro" shots that you all have been doing. By itself, the 10.5mm works great with my NX dome. I assume if I put a Kenko 1.4TC behind it, I will need to put a port extension on the NX dome. Is that true? If so, which one? One educated guess said it looked like the S&S SX extension would do the trick.

Can anyone confirm or let me know what they use?

b) Improving Performance of 12-24mm:

As many have noted, the 12-24mm seems to have soft corners when use without "aids" in the NX dome. I have searched, but I can't seem to pin down a consensus over what combination of port extensions and/or diopters are needed.
-Port Extension Only (and which one)?
-Diopter Only (and which one)?
-or port extension and diopter combo (which ones?)

I have seen suggestions of SX extension only/no diopter; I have seen 40mm extension w/ +4 diopter; and I think a +4 or +2 diopter only.

Any thoughts? (I just hope then answer isn't "any of the above...maybe") ;-)

thx for your time

Paul

bump!

I know this is old, ancient, obsolete system, but can anyone remember what they USED to do? ;-)

in the meantime, I did order a +2 and +4 B/W diopter for the 12-24mm - the least expensive experiment for that lens. Though I may have to do some North Carolina November pond diving to see what works. BRRRRRRR!

thx for any further info you can provide
