Olympus E500 lenses query

[sauer]

hi folks

 

sorry if this should have come under "general" thread not strictly piccies but bout equipment needed for em!!

 

 

 

wife has an olympus E500 that has barely been used ...im thinking bout nicking it off of her to try some wildlife piccies.....i know bugger all bout photography and was wondering what size of lense would i need zoom wise to get some good photos of wildlife at a wee bit of distance ...deer birds etc?

 

 

 

and where good place to buy them from?
