Gopro 2 with Dive Housing at Widest setting and the corner image is not clear

[coralgirl]

Hi all,
I have problem with my gopro 2 when in widest setting the corner image is not clear (blur) with a round mark. It looks like fogging but only at the corner, it does not affect the center and it only come out when recording at the widest setting (medium and normal setting does not show this problem). Anyidea what causing it? And how to eliminate this problem.

Sample of the video is available on vimeo.

Interesting.. I just opened a brand new Hero3 last night and examined it real close... I found a ring of residue around the lens, not sure what it was, but I had to use a microfiber cloth to clean it off... The inside of the housing lens also had smudges / residue..

You should definitely take a look at both under a good light.

They may need to work on their quality control....

Mix of fogging, dust, and the lens generally is poor

That's fog. The dive housing as well as the H3 will start fogging from the corners towards the center, the regular domed lens starts fogging in the center.

I got my anti-fog inserts from here: FogFree Anti-Fog Inserts | EelVision
they work great, fast shipping and the customer service is unbeatable.

I will try the anti-fog insert solution first and see how it goes. Thank you.

How about SRP filter? If it fogs, what is the best solution?

you're talking about two different things. the srp filter snaps onto the outside, so it won't be fogging underwater. I believe toozler is talking about the domed lens (as opposed to flat) that the older hero's had.

Ok reebok.

The SRP filter is a wet filter, meaning that it should flood once you get in the water. You might have problems with air bubbles getting stuck on the filter: you will have to remove it, shake it a little and clip it back on (while in the water). Bubbles from other divers under you could also get trapped, it's worth checking every now and then.

With a filter or not, the camera's housing lens (all of them - hero dive housing, hero3, etc.) can fog, that's why there are the antifog strips.

The domed lens I referred to was the housing lens, as reebok pointed out.
