Sony E PZ 16-50mm f/3.5-5.6 OSS II vs Sony FE 28-70mm f/2 GM
The bottom line
Similar coverage, different speed: the Sony FE 28-70mm f/2 GM opens to f/2 versus the Sony E PZ 16-50mm f/3.5-5.6 OSS II's f/3.5 — more light and shallower background blur. The Sony E PZ 16-50mm f/3.5-5.6 OSS II gives that up to stay lighter (109g (3.8 oz)) and cheaper ($249). It comes down to how much you value that extra brightness.
