question about lens compatibility with s100 and canon housing

[AandK]

I have a s100 with the standard canon housing which has the inon LD mount on front. My question is, can i use UWL-H100 28M67 with the LD adaptor as a wide lens? Is this the same as buying the UWL-H10028LD, or does it increase the distance from the port by using the adaptor? Or cause other problems?

The reason is, im also getting a Sony RX100 which has a m67 thread on the front, and i would like to be able to use the lenses on both cameras with the LD adapter on the canon or no adaptor on the sony.

Thanks

No you need the LD lens and there is an LD adapter also for the RX100. You can also buy the M67 thread separately as spare part if you don't want to use an Ld adapter on the rx100 but is not recommended
Other than the Mount the lenses are identical
Using the M67 to LD adapter will deteriorate image quality as the lens gets too far from the port

Thanks once again for your help. Can you please show me the LD adapter for the rx100? I really dont want to end up buying the wrong thing. So i should get the UWL-H10028LD and use it on both housings? I need to put a LD adapter on the rx100 with the m67 thread?

Thanks

You can either buy an M67-LD adapter (both nauticam and fix make them look here Wide Angle Lenses and Adapters for Panasonic LX7 | Interceptor121 Underwater Video) or buy the Inon UWL-H100 28LD and then change it into M67 using this part

I recommend bayonet mount as the lens is quite heavy and the thread gets ruined in time on both port and lens adapter
