In the next few weeks I will have the oppurtunity to capture a solar eclipse (with about 90% visibility) on the Z1. I am curious, will i need any specific lenses to capture this properly? What would be the best way to shoot this?

You will need a solar filter to reduce the amount of light to a level that won't damage your camera's optics (google "solar filter 72mm" for tomething like http://www.highpointscientific.com/store/listCategoriesAndProducts.asp?idCategory=6674). A supplemental telephoto might be desirable to increase the solar image size, but I would look at some published eclipse photos to see what field of view I wanted to capture the effects you see around the Sun at full eclipse.

Some people use a high density welders mask filter for viewing the Sun. For a special event such as this I'd want a filter designed for solar viewing.

Safety lectures sure to follow.

Absolutely, for sure, DO NOT aim the naked lens at the sun.

i do own the 2x 72 mm telephoto lens, it isnt very good (there is always a black ring around the picture at close range with it on), would it be compatible with a solar filter?

Sounds like you're getting some vignetting. That might not be so noticeable during the eclipse, although it would likely be made worse with the solar filter.
Perhaps there is a 4x4 solar filter available for a matte box.

You could get a good idea of the field of view and the vignetting effect by shooting the full moon.

You can make a quick filter by burning a candle under a piece of glass.

The smoke will make the glass dark, but you will be able to see the eclipse, just be careful as the black coating will rub off easily.

You might even want to try this on a clear protective filter that you don't care about, coat the inside and you got yourself a quick solar filter!

Perhaps some window tint film? ND gel for lights? Large peice of welders glass? How about the protective curtain used in welding bays? Get a chunk of that stuff and colour correct in post for the green cast.

You should be able to get your mitts on several countermeasures prior to your departure.

I sure like the McGyver-ness of the candle on the UV filter mentioned above...
