18-70mm or 18-105mm VR
having read kenrockwell reviews about these 2 lens above
having a dilemma to choose a simple walkaround lens
was wondering which of u will pick any of these lens above?
18-70 has closer min focus distance (0.38m compare to 18-105, 0.45m)) which attract me more, it has a scale meter which i find it useful when shooting video or landscapes (Hyperfocal technique)
but 18-105 has VR which is an advantage and has more focal length, Kenrockwell review this lens is soft at 18mm and has terrible distortions...
being used both. I'd say it depends on your need of VR.
if your cam is pretty bad in ISO handling. you might want to get VR because you are basically restricted to use high range of ISO for gaining extra stops.
the wider aperture on 18-70 is good as well. however from 4.5 to 5.6 difference is not giving you a noticeable benefit, unlike VR technology which is very noticeable.
in term of bokeh, 18-70 has an advantage because it is f 3.5-4.5
however in term of color redention, 18-105 giving more pleasant color looks.
the extra 35mm longer range is not giving a noticeable difference (for me).
my suggestion is if you are in need of 35mm extra reach then go ahead with 18-105.
if you have a good ISO capability, please proceed with 18-70.
I found out the focusing speed in 1870 is faster than tamron 1750.
