Finally jumped on the S5II for that sweet PDAF but im kinda struggling to pick a one-lens-to-rule-them-all zoom for my Japan trip in two weeks. Budget is $1300 max.
- fast autofocus
- f/2.8 if possible
- not too heavy
Is the Sigma 28-70 too compromised compared to the Pro version?...

honestly for a Japan trip you want the Sigma 28-70mm f/2.8 DG DN Contemporary for L-Mount. Ive tested both and while the Art version is technically sharper in the corners with better flare resistance, the 470g weight of the Contemporary is a lifesaver when youre walking 20k steps. It isnt really compromised unless you need that 24mm wide end. The PDAF on your S5II keeps it super snappy tho.
