I've looked at what you've said on the 2 cameras, regarding the batteries it doesn't matter whether you use NICAD or NIMH as far as the camera is concerned. The focal lengths though are very different and I would suggest that one of the 2 sites have got the specs wrong for one of the cameras, but I can't be certain that is the case.
Either I'm missing something or they are identical. Sometimes manufacturers give items (slightly) different model numbers to tell them where it was bought from/supplied to. Looks to have a decent spec for the price but watch battery life. The Canon my friend has eats them. I use a Sony or Fuji, both of which are longer lasting per charge. The Sony has the better lens. The Fuji is easier to use for more advanced stuff. The Fuji is still my favourite even though the Sony blows it away in terms of spec. Mainly 'cos it was my first. I think it looks better too. And it's got Porsche written on it!!!!
