In Topic: Nauticam 45 viewfinder wobble?

20 May 2014 - 01:29 PM

Hi Akoni, the part that goes into the hole of the housing has two O rings. And then there is the retainer O ring that you put on inside the housing once the view finder is pushed inside. So 3 o rings totally. http://reefphoto.com...roducts_id=5827

 

Diggy, understood. However, I am referring to the internal o-rings that allow the viewfinder to rotate.

Not sure if the 45 finder uses a single or double barrel o-ring to seal between rotating parts. I would guess mine is a single or if it's a double....one might be missing. I have added a vacuum system to my housing for added peace of mind. I'll ask the techs next time I'm at the store.


In Topic: Wide angle options for Canon cropped sensor

I've been using Canon 10-22, Sigma 8-16mm.
You really need big dome (at least 9 inch) for these rectilinear lenses, I tried it 6~7inch dome (with / without diopter) but really bad corner.
Sigma at 8mm is nice, it's wide, sharp, good contrast but sometime ugly light fall-off at corner if aperture is wider than f/8.
IMHO, 10-22mm is much better, specially zoom range (15-22mm) and mechanically too.

 

 

So the 200mm Zen and the Sigma 10-20 with +2 diopter will not work well?

 

I am hoping to stick with the 200mm vs having to get a 230mm. I need to figure out what port extension to use as well.


In Topic: packing and transporting my rig

Just picked up a Shapeshifter  from ThinkTank. Definitely like the pack for travel! I'll have to see how much of my camera kit I can pack in it...the housing will be the issue. My other carry-on item will be for most of my rebreather. Without a rebreather it becomes much easier and for many destinations carry-on will not be an option anyway.

 

Is anyone else using a Shapeshifter?

Would be interested in what you find out as well. Hopefully some folks will chime in soon.
