In relation to the cameras, digital and optical have a zoom range of 1x to 20x or more. In layman’s term , what is the equivalent distance of 1x? is it 1x = 1ft?, or1x = 1 meter? If I need to get a better picture with a distance of 100 meters, what kind of camera must I purchase? With the same inquiry above, if I prefer a video camcorder, what are your suggestions? Thank you.

No, there is no equivalent in feet or metres to the expressions 2x zoom etc. That expression merely indicates the difference in relative terms between the wide and telephoto ends of the zoom range. So a camera with a lens that zooms from 10mm to 30mm has a 3x lens - as would one with a lens of 5mm - 15mm - there is no fixed absolute for this term. 1x is not, in fact. used as that would merely indicate that the camera had a lens with a fixed focal length. Your question about what camera to buy to get a 'better picture' at a distance of 100 metres is a little difficult to answer as you dont say exactly what you want to photograph, or what you mean by a 'better picture' But go for one with a 4x or 5x optical zoom - forget digital zooms completely. If you want still pictures, also forget video cameras.

Optical zoom is the opportunity of the digital camera to zoom in with the lens. digital zoom is the opportunity of the digital camera to zoom in with this is computing gadget chip. Optical zoom is a few distance extra effective than digital zoom. 1X zoom potential you may zoom the cameras lens a million time. something sped up by 1 million equals the unique huge form, so 1X potential there is no zoom characteristic. What you spot is what you get (it truly is a telephone, so what do you assume).
