3 versions of Sigma 17-70......which is best for Underwater?

07 June 2015 - 12:07 PM

I'm finally upgrading from my old S&S D200 setup to a Nauticam D7200 setup.  I have a SIgma 17-70 2.8-4.5. which I seem to use once or twice on most trips.

While I'm buying new ports/ extension rings/gears, thought I would upgrade to the new Sigma 17-70 2.8-4.0 macro OS HSM.  I find, there are atleast two different versions of this lens sense I bought mine.


Sigma 17-70 2.8-4.0 macro OS HSM

Sigma 17-70 2.8-4.0 macro OS HSM  Contemporary or C


The Contemporary is the latest version, but has a 30% smaller barrel and different optics inside than the older models.   I know optics have come a long way the last few years, but wanted to get others opinions here before I buy.


Thanks in advance for you help and advice.
