Info needed for Hugyfot port

Hi,

Difficult to get answers from Hugyfot website.

My question concerns the use of a  Tamron 17-35 mm F2.8-4 Di OSD for Nikon with my Hugyfot D610 housing ?

I guess dome port 6.5 or 9 inches are the best one for that but i can't guess what would be the right extension lengh to use ?

Then does someone use such kind of wide angle zoom lens (or like Nikon 16-35) using the fisheye dome port (7 inches) ? What can be the downsides of this set-up ?

Thanks a lot,

Olivier.

Hi Olivier

With a rectilinear lens (such as the Nikkor 16-35 and the Tamron), you need the largest dome possible. This reduces to an extent the problem of soft, blurry edges - unless you are shooting into the blue where, perhaps, softer edges are not a concern.

So using a 7" dome with those lenses may result in the soft edge issue. 8" is better, 9" better still - but even then they may not be perfect.
