Which Aquatica Ext. Ring...

...for use with Aquatica 8" and 12-24DX lens?

been advised for both #18456 and #18457 (the last one if I am not mistaken is used with the 17-35 lens?).

Which one are you guys using that gives those sharp corners?

Jorge

Whichever one is 15mm long. I don't know the model number.

Cheers

I asked Blake this question at DEMA. 18456 is the correct ring for the 12-14 DX. The same ring as used with the Sigma 14mm.

Many thanks guys. I will not forget your help.
