Used Sigma vs updated one - help!
Hi - I'm sorry if this has been asked before! I hope someone can help me.
I have the opportunity to buy a used Sigma 17-70 DC lens for $249. It is NOT HSM. What is the difference between the two lenses in terms of image quality? I can't seem to find a comparison out there.
Thank you in advance!!
