Has some pros: If you take a used one or a new one, and more often in favor of 18-105 18-105 is less sharp in places, but there is not much difference with aperture 4 the range of 18-135 Cons below: When shooting in RAW, there is a rather strong vignetting at 18 mm (it is automatically corrected in jpeg, it is also easily removed by lens correction in lightroom).
