The weight UW and its form factor to me make the WWL-C more desirable than the WWL-1. 170 grams UW is not bad (450 grams less than wwl-1!) and it is 2 cm shorter. I am not sure why you say the the quality is not as good have you tried with the m43 mirrorless options? I saw somewhere a test with the Sony 16-50mm lens (worse lens than the 12-32mm or 14-42mm lenses) which describes it at least as good as the WWL-1.
I'm not sure I'm the best judge but I'll give you my feedback and thoughts on the setups I've been using over the past six months.
I have a Sony a6400 in a Nauticam housing and I have the WWL-C that I use with the 16-50mm lens and I also have the Sony 10-18mm lens that I use with the Nauticam 7" acrylic dome.
Due to Covid, all of my diving recently has been in Southern California and I tend to dive on deeper wrecks (50m+). That means it is usually really dark, a lot of backscatter & particulate matter in the water, green-ish water most days, I'm shooting wide angle, etc. I.e., they are very "camera unfriendly" conditions. I usually shoot with 2 x 15k Big Blue video lights and still need to boost my ISO for anything wide angle.
One reason I went with the acrylic vs glass dome from Nauticam is the 60m limit on the glass dome (yes, I know the Zen glass dome is rated to 300' and I will probably get that someday).
The bottom line is that I'm somewhat mixed in my favorite of those two combinations and still need to do more shooting with the WWL-C. If I had to pick one, it would be the 10-18mm with the dome.
The WWL-C is compact (relative to the 7" dome) but obviously heavier vs. an acrylic dome. The 7" dome is "floaty" but I've put some of the wheel weights with stickers on the bottom to help with that.
I've attached a sample photo with the WWL-C and the 16-50 lens. It is 1/60th, f5.6, ISO 1600 and 17mm. The corners are a bit blurry and this wreck was one of the shallower ones (40m or so). You can see that the corners get a bit blurry, but not too bad and if you are willing to crop a little, I'd say acceptable.
I think the WWL-C is 130 degree FOV at 24mm FF equivalent focal length, but I "feel" like I get a wider FOV with the Sony 10-18. I also just like the way the photos "look" better. It is hard to explain but I think that is why I find myself shooting with the 10-18 more often.
I'm also working on a long-term photogrammetry model of a 60m deep submarine so I want to use the same lens setup on all the photos.
I did a 75 meter dive recently on a TBM Avenger in very dark conditions and took the 10-18 lens and wasn't shooting for a photogrammetry model. I can't attach another photo to this post due to size limits but I will post it to another message so you can get an idea.
My overall conclusion is that I like the WWL-C but I need to spend more time shooting with it in different conditions to form a more complete opinion.
