I got my S2 last week and hopefully I'll get my Ikelite housing next week. My package includes the 5503.50 dome port. I intended to purchase the Sigma 14 EX but since I'm little concern about it's flare problem,
(I would like to include the sun rays in my pictures) I'm also considering to buy the Nikon 16 mm or the Sigma 15 mm instead (both fiseye). What do you, DSLR owners think, does anyone used the Sigma fisheye lens?


My question is: Does the 5503.50 port fits those fisheye lenses or I have to buy the 5503 port?
(The Sigma fisheye size is 2.5*2.9)

Thank's in advance

I know it doesn't specifically answer your questions, but I was able to eliminate about 50% of the flare problems with the Sigma by doing this:

I would like to try the 15mm or 16mm fisheye too but haven't obtained one yet.

The Sigma 14 is a good lens because you can use it on land as well as underwater without the barrel distortion of a fisheye.

I've used the Nikon fisheye and will be trying out the Sigma in the next few weeks. I think they are a very good alternative for digital. The barrel distortion is moderate and is easily corrected when desired using Panotools or ImageAlign (and probably others). Much of the time you won't feel the need for correction. The field is wider than the 14mm and the lens is much smaller and lighter. A big bonus is almost complete immunity to flare.

Regarding the Sigma vs. Nikon, I'm very happy with the Nikon. From what I've read on the net, the Sigma is a newer design and performs as well or better. There are the standard disclaimers about Sigma durability. The Sigma is larger although they are both small. The Nikon uses a 39mm bayonet rear filter as opposed to the rear gel holder in the Sigma. If filters are of interest, the Sigma provides more flexibility.
I love it when a plan comes together.

Read Thom Hogan's review of the Sigma 15mm fisheye here:

Thank's guys, one more stupid question: In the fuji's compatible ports and lenses page on the Ikelite site it's writen that Sigma ports "requires special order aperture gear #9094.56" what does it mean? wouldn't
it be posible to place the Sigma 14 mm directly in my port without an additional part?

Sorry that I post this query here, but I couldn't find any e-mail address on the Ikelite site :D ,

Thank's again

You are correct, you don't need an aperture gear. You control the aperture using the command dial that is on the camera.

I think Ike's port chart for the S2 needs some work.
