Hi all,

I'm going to update my 350D to 50D. I'm planning to buy S&S MDX-40D. What would be the right ports for:

1. Canon EF-S 60 Macro
2. Canon 100 mm Macro (usm)
3. Sigma 17-70
4. Tokina 10-17 FE

Teemu -

On the Sea & Sea website, there is a "system chart" which shows lens/port combinations for their housings - I can't seem to link to it, but it's right on the front page of www.seaandsea.com.

There are a number of choices for macro, between the compact macro ports and the larger ones. I have the NX custom macro port, which I use with the 60mm without an extension ring, and the 100mm with an SX extension ring. There are other combinations - those have worked for me so far and limit the number of ports you have to carry.

I haven't used the Sigma 17-70 - I'd call one of our sponsors (Reef Photo or Backscatter) and ask them about that lens.

For the 10-17, I've used it both with the NX fisheye dome (acrylic) and the optical glass dome with an SX extension ring. I've been told that the glass dome is the best for this lens. I like it's more compact size for travel, but you have the make the glass vs. acrylic decision for yourself. Optically, it's better than the acrylic dome, but it's not a difference that I think a lot of people will notice.

Good luck - the MDX-40D is a great housing. Have fun!

The Sea & Sea system chart is good but it seems that there are other combinations which can be used,
I.e. on the DX D80, one can use (I think) the NX fisheye dome with the Tokina 10-17 whereas on the chart it says that you can't.
Is anyone else using this port/lens combo?

As Rory says the Sea & Sea chart is at best confusing. Highly recommend you call and talk to one of the sponsors that carry S&S and get their insight. I use the NX Fisheye dome with SX Extention for the Tokina 10-17mm and it works beautifully. I did it originally so I could use the longer extention and the dome for the Canon 10-22. It really pays to talk to the folks who do it everyday.

Thank you all.

By the Sea and Sea -chart and discussion on this forum I have decided to go on with following ports:

1. Canon EF-S 60 Macro - NX Standard flat port
2. Canon 100 Macro - NX Standard flat port + SX extension
3. Sigma 17-70 - Optical dome + SX extension + extension ring 40 + zoom gear
4. Tokina 10-17 - Optical dome + SX extension + zoom gear

Hopefully these ports will work nicely. My target was to have minimum amount of ports and accessories for these 4 lenses. I think two ports and two extension rings and one focus gear will be acceptable when traveling by plane.

Teamu, Your port & extension ring selection looks good. May offer one piece of advice. I went round and round with Sea and Sea about the zoom gear for the 17-70 (non-HSM) I'm not sure which you have, but I'll tell my story anyway. Some at S&S say that that lens is not supported, which I know is rediculous. Then I got some one who finally knew the zoom gear for a Nikkor 18-35 (56350) was the correct one.

It arrived, I tried the zoom gear and it didn't fit! I immediately called our local S&S rep. He had no really good answer for me except to return it and pay an additional restocking fee. He still didn't know which gear to get that would fit. The deal here is that on the lens is a little lock switch to stop the lens from zooming. Well, that same little switch stops the zoom gear from being able to fit on the barrel of the lens.

I was left with two options: 1) Return the zoom gear, 2) keep the gear in case it would come in handy in the future and cut a notch a couple of millimeters in to the ring so it would it over the lock switch. I'm still looking for a good way to get it done professionally.

On a side note, the same zoom gear that you use for the 10-17 (Canon 16-35, #31114) will fit nicely over the lock switch of the 17-70. Just use a little tape on the barrel of the 17-70 to build it up a bit to fit snuggly. Even the fluffy side of Velcro will work.
