Sea & Sea RDX 500D Ports for Sigma 17-70 ?????

[AndyT]

Posted this in the U/W photo general section, trying here as well.

Asking this on behalf of a friend, I haven't jumped ship !

Is there a port and zoom ring combo available for this lens (Sigma 17-70) to use with the S&S RDX housing for the Canon 500D? Looked on the S&S site, couldn't see anything.

While I'm here, I have suggested he start of with the Canon 60mm macro, then the Sigma 17-70 as an all rounder and possibly looking at the Tokina 10-17 at a later stage. I assume the latter two will require a dome port, is there a "one dome fits all" solution?

Thanks

Hi Andy-
We'd suggest going for the 10-17 straight off as it is a great u/w and land lens. But to answer your questions, the 17-70 would use the 30104 Optical Dome port, RDX Port Base L 30109 and the 56350 zoom gear. The 10-17 will also be compatible and would require the 31114 zoom gear.

Many thanks for the great info !!!!

Would you please consider including the info on the Sigma 17-70 on a system chart for the 500D ?

Hi.

Is there a zoom ring available for the Sigma 17-70 lens to use with the Sea&Sea DX 80housing for the Nikon D80?

Thank U

Hello,
Japan does not list the Sigma 17-70mm lens in th System Charts, requests have been made. However, we have found several users in the U.S. using the 56350 gear with the Sigma 17-70mm lens. The 56350 is compatible with all SEA&SEA DX housings for Nikon. It is also suggested to use the Fisheye Dome Port (56401).

 

[AndyT]

Just to clarify - is it the Fisheye Dome Port (56401) or the 30104 Optical Dome port for the 17-70?

Hi there,
I use the 31114 also for the 17-70! Just some rounds of tape on the lens - and it works.
For the DX-D80 I use the optical dome with SX- and the 40-Extension.
So now i have a 10-17 and no need for extra equipment
Old thread on wetpixel: Sigma 17-70 (non HSM) - Wetpixel :: Underwater Photography Forums
I can give a link for first Results with the 17-70 if needed.

Remember there are several Versions of the Sigma 17-70!
I use the 17-70 without HSM!
The HSM-Version doesn't work with the 31114.

This info is outdated. #56350 gear does not fit the current Sigma 17-70 lenses with HSM motors.

Does anyone know what size will fit? It has a 78mm diameter.

Thanks,
