Hi,
...
My big concern is wide angle. Using 24mm through a flat port has always been considered to lead to bad image quality in the corners, lots of blur and color aberration.
Can you show us some shots at full wide open, where we can judge the corners?

In my opinion, the flat port issue at 24mm and wide opened aperture is exaggerated .
Her's some LX3 samples. you can judge by your self ( the IQ with the LX5 should be better):
24mm, f2.0, 1/125s, flash off.
24mm, f2.0, 1/125s, flash on.
24mm, f2.0. 1/60s, flash on
24mm, f2.0, 1/125s, flash off. Notice, the right corner is soft, this is due to the shallow DOF at f2,0.
24mm, f2.1, 1/125s, flash on.
25.5mm, f2.2, 1/125s, flash on.
24mm, f2.5, 1/125s, flash off.
24mm, f2.8, 1/320s, flash off.
24mm, f3.5, 1/125s, flash on.
About 22-23mm, f2.2, 1/100s, flash off.
Depending on the RAW converter used, one can get a larger FOW. Aperure and Lightroom crop the image to 24mm, other converters like Bibble Pro don't apply cropping or any corrections. You can see more vignetting and softness on the corners.
I am surprised and disappointed that no one is offering a true dry dome port yet. Or have I missed that?
Thanks all!
Don
10Bar, UK-Germany and Recsea have dry dome ports for their housings. These domes can be also used with dry WA converters like the Panasonic DMW-LWA52 and the Sony VCL-D0746, both are .75x converters and give 18mm with excellent results.
At 24 and 90mm, the lens of the LX5 extends to the maximum of it's length, this allows zooming with dry converters and also allow the use of dry macro lenses like the Raynox DCR-250 inside dome ports.
