RX100 m6 Nauticam N50 short port

[j0rd1]

Hello,

I've been using the RX100 m6 with the standard port and I would like to get the N50 short port for some wide angle. Now the question comes...

I see two different options from nauticam, the port with bayonet integrated #38703 (can't be removed) and another with M67 thread #38701. Is there any difference in terms of image quality/distortion if I buy the port with M67 thread #38701 and attach the bayonet conversor in front #83213?

The first option is cheaper of course, but the second can give some flexibility using non Nauticam wide angle lens.

Thanks

Jordi
