Water or weather? The only accepted, graded rating for water resistance is the IP (ingress protection) code. I've not seen any DSLR/SLR yet that has an IP rating. You can buy the "tough" type or underwater models which are effectively underwater compact cameras and commonly carry an IPX8 rating for water and IP6X for dust thus read as IP68.

I've had A lenses suffer from water ingress whilst shooting in Scotland in constant drizzle and were used on an LX. The camera was fine.

Just needs a piece of tape over the battery cover.

Alternatively, a light application of petroleum grease (Vaseline) on the battery cover threads works really well or go full on and use a drop of ACF-50.

No, that is wrong. The LX manual describes it as "moisture resistant". It specifically says "it is not waterproof, protect the camera from rain or splashing water"

I doubt the sanity of anyone exposing a camera of the LX's age to excessive moisture, let alone water. It was a well designed camera of it's time but the years will take their toll on the integrity of any moisture seal.

Always better to use a first post on a forum to introduce oneself, only my opinion.

At least it wasn't straight onto the sales section to unload a few items.

Lots of film bodies, a couple of digital ones, too many lenses (mainly older glass) and a Horseman LE 5x4.

You can use any lens/camera in light rain, and they might survive OK.
Weather sealed kit should be fine (but is not guaranteed).
A non weather sealed lens will probably get a little water inside - there will usually be no immediately apparent problem with this - but there's an increased chance of fungus growth subsequently.

I had an SMC Pentax-A 35-70mm f/4 lens that was caught in an unexpected downpour. After we reached shelter, water was poured out of the lens, probably half a mugful, but after drying it out it continued to give good service for many years.

Not recommended as the norm!
