Well I took some images with the lens...I have to say, that initially it was very nice.. until I hit a thermalcline and the thing fogged up...
They have a comment about that in their instructions.. but if the air space is sealed... then the moisture is due to them putting it together in a high moisture room.
Well it does work, and works better (when not fogged) than I expected...vis was not very good the day I used it... which is not the place to be using a wide angle... but I decided to try it anyways...
Here are some of the good images:
I have tried that jelly fish picture before without the wide angle, and I cannot get the camera to focus on them.. this was easy....(note: remind me to remove the fins from the background before printing.).
This is a cropped image.. very nice image quality...the dark look is because you loose some light with the lens...
Here is the whole image:
Then it fogged on me..(10 degree temperature drop)..
I still tried different types of images...with the bad vis and all.. include some natural light ones (using manual white balance and with auto white balance)..
The lens had just started to fog when I took this:
And was in full fog by the time I got to try this one (notice the red light.. it's from adjusting the white balance for deep, bad vis water)..
So my take is that it works.. and if the fogging can be resolved...would carry it with me... the next day vis was much better, and this image would have been far better with a wide angle:
One other thing.. you can zoom, just not very much or you will not be able to focus...
But I found that the focus range with the camera set a 28 mm was very good...
