So what I meant to say is that what exactly is the difference between 18-55mm lens (in general, not specific to any company) and a 18-105mm lens. To me 18-105mm lens looks much better (not considering price), but then why people would also buy 18-55mm lens? and then probably another lens for 55-105mm (if it exists, or similar case for other mm).
The point is that if 18-105 can do all the work of two lens, then why do people buy two different lenses?
And I have seen combos like
- 18-55mm + 55-105mm
So which one should i go with?
