Canon T2i - Nauticam 550d

[furby076]

I have the nauticam 550d for my t2i with the 18-55 lens and base port.

What is needed if I want to get the Tokina AT-X 10-17mm to work with it?

Regards

You might ask Reef Photo in Ft. Lauderdale - will probably suggest an appropriate dome port. Or, you can wait until they reply to your posting.

Check with Backscatter also.

I went with the Zen 100mm dome port with built-in extension ring from Reef Photo for my Nauticam 550d and Tokina 10-17.

You need a 20mm extension ring + dome port + gear. There is an 8.5" acrylic dome or there are Zen domes, the small 100mm Zen dome now has a new mount that includes the 20mm extension, saving quite a bit of money.

With Nauticam you can also use Sea & Sea, Aquatica or almost any other manf. ports. I use the S&S Optical dome. Nauticam has a 20mm extension ring that has the S&S adapter built-in.

I use the Sea & Sea acrylic 6" compact dome port on a Sea & Sea base port + Sea & Sea Housing - works well and I like the size and weight of it.

Are there glass domes instead of acrylic? I worry about plastic scratching. Of the domes - Zen and 8.5" acrylic, or other - is there a dome that is recommended as multi-purpose. Meaning can I use the zen or 8.5" on a macro lens when I eventually get it? Buying all these domes is damn expensive and it would be great if there was a single dome that could handle it all (or most of it)

Thanks so much!

The Zens are glass.

The Nauticam 8.5" is plastic. Yes, it does scratch fairly easily. But you can buff them out if they aren't too deep. The plastic is a lot lighter.

Glass tends to be sharper and have better corners, it is harder to scratch, but if scratched is pretty much impossible to repair. It is heavier.

You would need a larger port to be multi-purpose. Like the 200mm Zen, the Sea & Sea Optical Glass port, etc. Those do accommodate a variety of lenses. One popular lens to use with a dome port is the 17-70 Sigma; very sharp and can do sort-of macro- to sort-of wide angle. You do need a long 60mm extension for it.

Regular 60mm macro lenses can be used, but you will not get very high magnification with them, nor be able to shoot very close, due to the physical size of the dome port.

The advantage of the Zen 100, although limited to the Tokina 10.5 FE (or 10.5 Nikon), is that it is so small that you can get quite close for close focus wide angle shots. You do need to shoot at about f/8 or above to have good corners, where with a larger dome you can open up the lens more, making them a better choice for blue water shots.
