What's the difference between Optical Zoom and Digital Zoom in digital cameras?
Optical Zoom is good- it's actually changing the focal length of the lens elements to zoom in.
Digital zoom is crappy- it's like having a picture on a TV screen and taking a smaller piece of it to zoom in- so your'e just enlarging it and magifying the pixels, not getting any better detail.Optical zoom is when the lens actually moves, it's a physical mechanism. Digital zoomed is when the image is made large by software but the resolution is not increase, so the image starts getting little squares.
Optical zoom is the best, because effectively the resolution stays the same when the picture is magnified.
I know, Optical zoom is the one comes out of the camera and digital zoom doesn't. But other than that how are they diffrent which one do you recommend when I am thinking about buying a
5megapixel 5X digital zoom. or 5.1 Mega pixel w/ 3x Optical zoom.
the one with digital zoom is lik $ 119 and Optical zoom is 150
I am going to be using this camera for mostly family pictures and trips.
