DC Q's

Canon Powershot has 5X optical zoom, is it better than 3x optical zoom?  When I zoom to 5x optical, does it has noise?   Thx.

generally 5x is better than 3x and optical will not gain noise

in the last few years digital camera has matured and replaced film cameras

one of the nice features of digital camera s  has always been the optical zoom
the more zoom , the fun you have with the camera,
another feature people want in a digital camera is small size

optical zoom isn't a feature unique to digital cameras.  film cameras had optical zooms for many decades.  it's the digital zoom (which sucks) that is unique to digital cameras.

Good question .. and some good answer ..  

Case A-->5X zoom is better then 3X zoom when that 5X zoom is better ..   

Case B-->3X zoom is better then the 5X zoom .. when that 3X is better ..  

A--> If higher zoom range is what you want.

B.--> If image quality is what you want. (that is why, most higher model DC or Lens, DON'T offer high zoom range.

For Noise -->  In photography world ..  noise is not = noisy sound ..  you better know about it first ..  

So ..are you asking about the "sounding" noise? or the "photography" noise?

about optical zoom,
in film camera, i thought only SLR cameras have zoom lens

the zoom lens in digital camera s  are designed to make  all film camera obsolete

the advances in digital camera s  so far have been , better sensor s for low light
more megapixels  for details, and more zoom .
dont forget more portability, more functions such as video

Hi Maanmo,

You must be much younger than I thought.  Many if not most normal Film point & shoot have zoom lens.  They were very common.
