Thanks for the negatives about low volume masks, I was thinking the same thing but have never used a low volume mask. I'll have to try one though to figure out for myself if the pluses are worth the negatives.

thomjinx:I dive a black frameless, and I like it a lot. I love the wide field of view. However, I would like to point out a couple of potential negative 'features' of this AND other low-volume masks.
Yes, it doesn't take much to clear it. It doesn't take much to fill it up, either! Others have noted the problem with getting water up their noses, or bubbles when clearing, etc. It only takes a very small amount of water in the mask for it to be annoying.
The spoonful of water that I used to leave in the bottom of my mask (for the purpose of de-fogging) is enough to be a problem in a very-low-volume mask.
I have a mustache, so it is more difficult to totally prevent leaking. If I were clean shaven and the mask fit well, it might not bother me as much.
The other thing is that the combination of a low-profile mask and a 2nd stage with a narrow exhaust tee can give you lots of bubbles right in front of your eyes when facing horizontally. I made an extended exhaust tee myself. Looks cool, solves the problem.
On the plus side, another reason the Atomic Frameless is great for photography is that you can get your eye closer to the viewfinder of the cam, because the glass of the mask is closer to your eye. This really helps when I am shooting video, since I don't have an LCD back on my housing.
All engineering involves compromise, and these negatives apply to any very-low-volume mask. I just wanted to offer my observations.
jeffrey-c:Just had to say "nice post". It's nice to see someone put in thoughful pros/cons on a topic.
Divedoggie:The subframe mask looks great, but when I tried it on I found that it smashes down on the bridge of my nose, and I don't have a big nose!
RJP:Same here. Was in my LDS trying one on tonight and I could just ever-so-slightly feel the bridge of the nose on the mask pressing on the bridge of my own nose. While I can't say for sure without trying it, I'm guessing that at depth it would press down much harder (ie: much more painfully) with a bit of a squeeze on.
