    Last night when I was shooting some lightining I got cut into a flash ice rain but I managed to get to cover in time but then I saw that my Panny G2 was a little wet, mostly, on the lens barrow and when I started to clean the water I saw that some water driped at the lens mount and when I got the lens off (just to be shore I keep the camera with the lens point downword (I case some water was there it wouldnt fall on to the senzor)) I found that some water was on the lens mount, even close to the electronic contacts. Luckely my camera survived, for now, but makes me wish for my old (and now dead) Pentax K200D in this situations.

    Now to the subject: I was wondering if I could stick (with glue) a small ruber or ruber like (essentialy anything water repelant) on the lens mount, something like the stantard weather sealed lens have, for a minimum of protection at least for the sensor and electronic contacts.

    Maybe a thick rubber band around the base of the lens and mount ? That would form a decent seal.

    Would only work if the manual focus ring wasn't required and it'd be pointless on a zoom where there are more moving bits (or get the new weatherproof Zuiko zoom).

    Probably fine for the primes though.

    A quick google and I found these guys

    - LensCoat

    I suspect you could make your own neoprene cover that overlapped at the mount and even protected some other body elements while still allowing you to shoot.

    Wich of the 4/3 lenses are weather sealed, I woldn't mind for slow AF. The only thing keeping me from going back to Pentax is the really good portability of the M4/3 system and now that we have a sealed camera only some few (actually usefull) weather sealed lenses would make it perfect for me.

    No, nothing will fit between the camera side mount and the lens. You could use an o-ring by milling a groove into the lens mount, but that doesn't seem practical. The mount may not be thick enough. You need to have a milling machine. No chips in the lens. Sending it out to a machine shop would be very expensive.

    If you shoot in the rain a lot I think it makes sense to invest in a true "weather-proof" system. If not, maybe just grab a waterproof point & shoot option so you can get some shots no matter the weather.

    The new Olympus 12-50mm is weather sealed. I don't know of any others, yet. Hopefully there will be more soon.

    Yet there are the bigger boys (Four Thirds) that are weather sealed and can be used with the MMF-3 adaptor (wich is weather sealed as well) even thou there may be slow to AF or at all. My only other option is to go back to Pentax system because Olympus Four Thirs isnt all that smaller then Pentax K-5 with the pancake lenses, and I'm loving my Panasonic G2 to much (even with the dissapointing ISO performance).

    Very true. In the end we each need to use the gear that works best for us. I don't worry much about weather sealing, but others need it for the type of shooting they do.

    While it would need re-application with every lens change, you could use automotive dielectric grease on the flange and contacts.

    the following 4/3 are weather sealed.

    50mm f2 macro
    14-54 Mk2
    50-200 Mk1 and SWD
    12-60 SWD

    you could see if someone is parting the 12-50 kit lens that is m4/3. then you need to cover the body, maybe the old standby of the clear shower cap?

    No grease or lubricant is ever supposed to put on the lens/body mount or the electronic contacts. The contacts are gold plated and exert very little pressure; any sort of grease would goo everything up.

    Before replying with any sort of It will work because..., put that stuff on your gear, try it out for a week and tell us how it works.:dash2:

    When that stuff migrates to the sensor, or some other component that doesn't work well with grease, are you going to tell him to spray it down with brake cleaner?
