No idea, but I have a brand new one, TTL II, for sale! Still in the box. Let me know!

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.

reefkeep, yes it is normal for there to be a little "play" in the port/extension ring connections. I agree that at first it is pretty unnerving, but as soon as you get in the water, the pressure of the water pushes them together. As long as you have properly maintained your O-ring, it will be fine. Always test it first without a camera when you first get your housing. As well, always dunk test your set up in the camera bucket or in the water. Look for a stream of bubbles that would indicate a leak!

Also, only the first extension ring or port will be actually locked by the S&S locking mechanism. Everything is marked with an "OPEN" and "LOCKED" mark. I've made it a habit to always look at those before I get in the water and every-now-and-then when I'm shooting under water. It is pretty obvious if your dome gets turned while attached to an extension ring...the shades are off center. Even if it does get turned, it's not the end of the world. You actually need to turn it pretty far and apply a lot of force to get those things apart on the surface.

Also a question for Alex,

I was disappointed in the corner sharpness of my 17-70 (non HSM) at the wide end. I see that a couple of your pictures above suffer from the same. Is this normal for this lens? I was using mine behind a S&S Optical Dome (6in/15cm) and thinking about purchasing the larger NX Dome to hopefully resolving the issue.

In Topic: Zoom Gear Doesn't Fit

Well. I think I'll probably keep the Zoom Gear and follow David's advice of filing a notch in the Ring. That way I'll have another toy and, who knows?, it might come in handy in the future on another lens.
