Canon 10-22 and Ikelite ports

[kreuzerkrieg]

Hi!
I'm planning to purchase above lens. According to Ikelite port chart two ports can fit this lens, 6" (~200$) and 8" (~700$). Can onyone explain what is the gain of 8", is it worth the 500$?

The price differece in the US is about half of that. It is also a two part system.

There is a huge size difference between the two ports.

You can do over/under easily with the 8".

AFAIR it is US (B&H Photo Video | Digital Cameras, Camcorders) prices
Over-under shots it isnt thing you do often (at lest I dont) is it worth four time overpaying? is it any additional value except over-under?

Just to be precise
for 8" assembly you need:
8" Dome Port 380$
1.75" FOCUS PORT EXTENSION 166$
1.75" PORT EXTENSION RING 118$
Super Wide Mounting Body for 8" Dome 118$

782$

versus

Dome Port for SLR Housing 190$

You'll get sharper corners with the 8" port.

It is interesting that you post this question as I am currently about to purchase an ikelite housing and one of the lenses I am going to be using is the EF-S 10-22. From looking at the Ikelite port chart for Canon lenses, I thought I only needed the following items:

5510.22 Ikelite Port Body for 8" Dome Port for Nikon 12-24mm and Canon 10-22mm Lenses B&H Price $140
5510.45 Ikelite 8" Dome Port with Shade and Cover B&H Price $380

Is this not the case?... I have to say looking at the Ikelite chart for what you need can be a little confusing... If you went the 6" dome route... you would only need the 5503.50 at around $190. So i was thinking it was only a $330 price difference.

If anyone knows for sure I would appreciate confirmation that I am right/wrong.

2bladephotog: good point... will I get sharper corners in case of fisheye or any WA lens?
2BWDiver: sure you dont have to buy focus port extension but dont sure regarding the extension ring. in the best case it will be 250$ less that makes the price more reasonable...

Wow, I'm in the same boat (excuse the pun!), let me know which you ultimately end up with!

Will wait for alcina, for sure he/she knows

I'm not sure about the fisheye. Just contact Ikelite. They're pretty easy to get a hold of. I use the 10-22 in the 8" dome port and like it quite a bit for what I do.
