It sounds like mechanical vignetting - the shadow will come from the lens not getting a lot of light when zoomed all the way out - if you imagine the lens is in a tube, it will have shadows / a lack of light caused by the internal barrel of the lens, but as you zoom in the lens will move up this tube, and more light comes in, less shadows/vignetting is experienced. This is of course a bit of a guess, as I don't know the exact mechanics of your camera, but I'm assuming the wide angle converter sits over the top of the normal lens, and doesn't replace it.
lumix fz38 vignette help
after adding a wide angled lens to the fz38 today with the adaptor ring
im finding until ive used the zoom to about x6-x8 there is a shadow all the way round the picture
(vignette)am i doing something wrong? i.e the settings or is it usual to have to zoom a way out to
get rid of the dark ring round the pic?
thoughts would be appreciated!
below is the lens ive added

o and just to add to the story the picture is actualy showing 4 sections
the adaptor ring is in 2 halves as is the wide angle lens as its got the macro lens beneath it

Methinks thou dost have a date with a pool and a grid, but the tiles will do at a pinch.
ok i admit uve totaly lost me chris lolMethinks thou dost have a date with a pool and a grid, but the tiles will do at a pinch.
what on earth does that last statement meen ?
anyway chris i thought you would be a wizz with a lumix
OK, I'll spell it out. If you take your rig into a pool you can test it all out, particularly today when it doesn't matter given that there is no film involved (apart from electricity, it's effectively all "free"). You're best to do so with your own grid (in this case, for your particular purposes) in order to establish what the wide angle lens does, and doesn't, do in whatever configuration. Alternatively you could use the tiles (and grouting) at the sides of the pool, if it is of that type.
You either didn't get to read my tale of woe with that particular camera or have forgotten. I haven't got it any more, in fact Richard in Tasmania, specifically his missus, now has it and seems perfectly happy with it, or was last time I spoke to them.
Incidentally, it's no big deal, but I really do prefer not to answer to "Chris". I'm still enough of a continental to say that it isn't my name. Whatever, though.
this camera isnt for a p[ool or any kind of water for that matter mate or should that be christianOK, I'll spell it out.

and yes i remember your tales of woe? strange ive had no such problems
o well thanks for the input !
Which leads me to think that you use a Microshaft computer thingie, as against my Mac one.
Well, did you at any time say that this was an above water problem? It's often a below water problem, hence my assumption, right or wrong and it happens to be wrong in this case.
Regardless, try the exercise above water - with a grid. Print out an A3 (preferably) page on high quality matte paper with a 10 mm x 10 mm grid at about 1/2 point in size. You should soon learn what does, and does not, work, at whatever camera setting.
It's actually much easier above water, stick the camera onto something immovable, don't move the grid at all, snap away at various settings and Bob's your dad's brother.
