i would say u wont really miss the 15mm btw 70mm and 85mm....
the 18-70mm kit is actually quite good. but wont be that good as a walkabout if u want some range. i think 85mm not enough also.
best save up to buy a 18-200mm than sell both. you are not losing anything on the aperture, cos all 3 lens are about there. in 18-200mm, u get wide, as well as tele. wat u might lose is..... money :bsmilie: :bsmilie: :bsmilie:
depends on wat u like to shoot lor.....
