Also the rx100 has a lead shutter maybe even the canon 1”

I think most of the higher end compacts use leaf shutters, though I don't know why (maybe it allows the camera body to be smaller??).  I know that the Fuji X-100 series has a leaf shutter.  Mirrorless and DSLR lenses use a focal plane shutter, and that limits max shutter synch speeds to around 1/250. On the other end of the spectrum, leaf shutter lens in the medium format world are hand crafted, incredibly expensive, and highly sought after.

On my last dive trip, I took my LX100 and did some photography of some inane piece of coral on a wreck, and progressively bumped up the shutter speed.  It really does darken the background.  It was kind of fun. I will have to play with that more on the next dive trip (sadly, not until October), see how I can use that to my advantage.

Is this still for sale?

Backscatter just posted their LX100 II review.  They used the AOI UWL-09 Pro wet lens, and the images look good.  If I go down the wet wide angle lens route again (still undecided), I lean towards the Nauticam WWL-1, just because Nauticam now has a float collar for that beast, and the AOI lens does not have that

There were a few points in the  review that were incorrect: the camera has a 4/3 sensor, but the image circle on the lens does not cover the entire sensor, though it is a multi-aspect ratio sensor.  The camera uses about 81% of the sensor (it's the 21 MP sensor in the GX9, the LX100 II uses 17 of those 21 MP).  The other point, which is noteworthy is that the electronic shutter does not determine flash synch speed.  The LX100 II, and many other compact cameras, and some high end medium format cameras, has a leaf shutter mechanism.  I don't fully understand them, but as I understand it generally -- the shutter mechanism is in the lens body, not on the focal plane with the sensor.  It's actually a really neat feature, it makes the camera fantastic for "strobist" photography on land (google David Hobby and Strobist).  On land, you can shoot with a leaf shutter camera at say 1/1000 or 1/2000 shutter speed, the flash will still synch and light your subject, and you can kill the ambient light in the background because the shutter is so fast. It's great on those sunlit days where the sun is high and the light is harsh.  Underwater, it is really usefully to getting a darker, or even black background, like on a macro shot.

Backtracking to the beginning of the thread: did you try the WWL-1 with float collar? I haven't tried it either way myself, but I understand that the float collar makes a big difference for handling.
 
Also, out of curiosity, what modification was needed to make the LX100 II fit? I thought it was identical on the outside to the first version.


I feel silly about the WWL-1 because I had it, hated or and sold it. At the time, there was no float collar. If that had existed when I had the WWL-1, I probably would have kept it. Maybe I’ll try again?

So Nauticam has a conversion kit they sell for $30 to convert the LX100 housing to accommodate the LX100 II. It replaces the pieces that operate the zoom lever. I’m about to send my housing in for servicing (it’s time), and I have already asked them on the phone already to install the conversion kit so that I can use the new camera (the parts are quite fiddly and I don’t trust myself to do that conversion). They asked me to send the new camera so that they can check the fit.

I’m just pleased that to get to upgrade my existing housing to accommodate the new camera. It’s actually not unprecedented: the Nauticam housing for the GH3 accommodated the GH4, with similar conversion kit.

By the way, as a land camera, the LX100 II is a LOT of fun
