I went to Best buy and looked at their cameras. I saw one that doesn't have a lens that pop out, as like most cameras do. So I asked one of the people and they said the lens are zooms in the inside and there's no really difference between them. I just think they are trying to get my money...
So what's the real difference between them, or is the best buy guy actually right?
If the lens doesnt pop out then perhaps its a digital zoom only which doesnt compare to an optical zoom. In my opinion (feel free to prove me wrong/disagree) I think the digital zoom is a waste of time and the optical zoom is the really telling factor. You can use PhotoShop or PaintShop Pro to digitally zoom the image afterwards with similiar results. The optical zoom is the key as you will get a sharper image with more detail. Its not going to be pixelated and the like. Personally, I wouldnt purchase a digital camera that didnt have some kind of optical zoom. As for the digital zoom, I have never had any desire to use it.
RTFM or Box if you want to know whether it is Optical or Digital zoom, or a combination thereof...
Some 2x and 3x optical zooms are internal lens movements, and not detected by viewing the outside of camera...
But you will see a 10x or 20x optical zoom moving the lens...
