Hello isulami, and welcome to the friendly Camera Labs forum!
To enjoy your stay here please have a look at the house-rules
I'd have voted for the 70-300. But it is also a very wise decision to just use a single lens and try to find out what youreally long for:
- large aperture prime to isolate the subject with shallow dof
- more reach for far-away subjects
- wider angle of view to take in more of a scene
The 18-105 gives you a great range and only after some experience will you know what gives you the best "bang for the buck" in an additional lens...
