Hey everyone, I just bought a Sigma 18-200mm F3.5-6.3 DC OS lens for Nikon, and I was wondering if its normal for it to have some resistance while zooming about halfway in. The zoom will be smooth to about 50, 50-80 has noticible resistance, while 135-200 will be fine. The retraction feels smooth with 0 resistance. Is this normal, or should I switch it?
