I just got this lens to use with the Dome Port #18414. I have the recommended extension #48457 (54.5mm). Something is off the lens at 14mm with about 1/4 inside the dome port opening causing serious vignetting not seen with other wide angles lens with this port.

Coourious what extension to you use with this lens/dome port combo.

FYI I have contacted Aquatica and they are are working on a solution but I figured I check here if any one else uses this lens with this housing

Thanks!

Looking at the specs for the 14-30 vs 14-24 lens the total length with lens extended (for the 14-30) is 114mm vs 125mm for the 14-24, this says that the 14-30 should use approximately 11mm less extension than the 14-24 as a first pass guess, however the port charts show the same extension for both lenses, which seems to be an error. A starting point would likely be the 48462 extension at 39.5mm long which is the next smaller extension at least on their extension length chart:

a 48455 plus 48456 (25.5 + 16.5) for a total of 42mm is another possible combo. If you had some other extensions already for other lenses you could try them yourself.

If Aquatica are working on it probably best to wait for them as this assumes the same position for the entrance pupil in both lenses. They are probably close but may vary a bit in how far they are from the front of the lens.
