Sigma 28-70mm f/2.8 DG DN Contemporary (L-mount)
The 28-70mm f/2.8 Contemporary is the compact value standard zoom on L-mount, just 470g with a 67mm thread, in the enthusiast tier. It pairs especially well with IBIS bodies like the Panasonic S5 or Sigma fp, since it has no optical stabilization. Choose it to keep weight and cost down; skip it if you need 24mm-wide framing or plan handheld video on a non-IBIS body.
