Sigma AF 18-50mm f/2.8 EX DC .What do rhink?
2 months ago

Hi.
I want some imput about the Sigma AF 18-50mm f/2.8 EX DC (no OS nor HSM) quality.
I have a D90 and a 50 1:1.8 D wich I enjoy but want shorter focals for indoors family and kids. I Have a nikor 18-70 1:3.5-4.5 to (no VR either).
So what do you think is this lens giis enoug to replace the 18-70? How good is at f/2.8? Or will I be seping down to 3.5 any time?
I'll get it used so what shoud I look and take care of?
Should I look for a VR/OS version?

Thanks in advance.
