I found a Sigma 28-70mm f2.8 lens for EOS on the used shelf of a local camera store. It is a "two-touch" zoom with a 72mm front filter size and metal mount.
I cannot match it on the Sigma site or at B&H. The current models have a 77mm filter. Can someone tell me what model this is and if this model is any good? Are there any aspherical or other exotic elements in it?
