Focusing Zoom
Does optical zoom have anything to do with focusing?
No
All lenses need to be focused in order to get clear sharp images. This can be done manually or using an auto-focus scheme
An optical zoom is the range a zoom lens covers from its widest field of view to telephoto (if applicable)
Point and shoot cameras list optical zooms in terms of 3x, 4x, 10x, 24x etc.
DSLR zooms list their ranges in terms of actual focal lengths; 18-55 mm, 18-200 mm, 200-400 mm, etc. Listing a zoom used on a digital SLR camera as an “X” range is rather meaningless since a 12-24 mm zoom and 200-400 mm zoom are both 2x zooms
