What is the relationship between optical lenses and the digital optical ranges?

canon digital camera 8x optical zoom image

John D

I have a HP Photosmart 945 with an 8x optical and 7x digital zoom. I am considering a Canon Rebel for a replacement and want to know what lens I would need to meet or exceed the range of the my current camera.

Answer
Firstly, you can disregard any importance in using digital zoom. The HP 945 has an optical focal length equivalent of 37mm-300mm.
So, you will need a lens with a focal length in that range or more. You might have to buy at least two lenses to achieve that, though.

What recommendation for a digital camera brand and model?

Hime-Sama

I would like to buy a digital camera but I'm not sure what to look at. Design is not an important aspect. What I would want is that it can produce a good quality picture and doesn't need much editing. I'm not so sure whether to pick a higher megapixel because some review states that higher doesn't mean better, though I'm not sure why. Could someone give me a guidance in choosing a good digital camera? Thanks. =)

Answer
I would suggestion these are good quality digital cameras that take good pictures, good of megapixel, slim, etc.
