why are you returning the sigma?
In my outings with the Sigma I found that I was only using it at the wide end....anytime I need something in the 20mmish range, the Loxia 21 will always get the nod. The Loxia is my go-to. I'd rather carry the Loxia + a 12mm prime than the Sigma.
If I didn't have the Loxia, I'd keep the 12-24.


..off to look....that could be bad...
