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

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.

My thoughts would be that if you can use just half the adapter ring then you should get rid of the worst of the vignetting. The longer tube is probably allowing for it's use with a long lens too. That's how it works on the canon.

Yes - the shorter the 'tube' that the light has to get down, the less the vignetting should be. That's kind of what I was trying to say in my first post, but in a shorter more concise way!

ok here is how i set it up earlier

the adaptor ring is in 2 halves when its split it screws into the front of the camera

the 2 lenses fit onto the frontof that ring

the adaptor ring cannot be any shorter as it wont allow normal opperation of the lens coming out of the camera itself!

the adaptors and lenses are a normal addition to this camera and wondered if maybe its a setting within the camera itself

Are you using the sun shade thingy that comes with the camera ?

It definitely sounds like a physical effect of having the adaptor ring and additional lens fitted. I have an FZ28 and can't recall any alterations you can make to the software for fitting the additional lenses available for this camera.

Thats a shame though becuase I think these camera's are fantastic and I was considering the extra lenses myself.

No, I'd say it's a physical limitation of the camera / lens design. You can remove vignetting in some photo editing software.
its ok mate ive found the settings in the menu

it gives the facility to turn on the conversions seems to work

although i need to suss out if the adaptor ring needs both halves using or just one half ?

and is it to be used with or withut the macro lens that is at the bottom of the main lens !

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. :D

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. :D

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.
