Just to add a bit. I've been monitoring this thread and asked them to see what can be done. Puffer, they do listen and I think some of your comments are a bit out of place.
If you shoot into the sun or have it right over the lens you will get flare. That's prevalent on every wide angle lens above or below water. The dome makes it worse, that's why they have a shade.
Strobes actually can also be positioned with longer arms out and behind the lens pointing outward slightly. Use rim lighting to light your subject. Positioning them can be critical. Every w/a dome shooter has this issue.
I definitely see the issue you guys are bringing up about fogging, and Sharon is right, keeping it out of the sun, storing it in a cooler, etc is very important. While fogging can be controlled in a plastic camera housing with silica gel, obviously this can't happen with the lens. Taking any camera equipment from a warm environment to a cold one will cause fogging. However having it get worse during the dive is weird.
Fantasea is concerned about the extent of this issue and is supplying me with a Fuji version (same lens different mount) of the lens to test here in Seattle. We have pretty harsh conditions here, although I may have to get a hair dryer to reproduce the warm sun right now! I will do my best to follow their current instructions, and also to reproduce the issues you're seeing. Maybe there's some other work-arounds. If there's a problem, I can work with the product manager to see what can be done to help reduce it.
Your lenses do come with a one year warranty, if water is getting into the lens , it will be taken care of as Sharon has said - if you write them directly, or fill out a warranty claim on their website. Further support can be found
here.
I'll post what information I can figure out with the lens in a week or 10 days after a few dives with it. Note, while I'm a dealer for them, I think you guys know I'm pretty honest in my appraisals of gear.
Thanks,
Jack
