Confronto con Tamron 28-75mm f/2,8 III RXD e Sony 24-70mm f/2,8 GM
It may be a good lens on a Sony A7S (II) but the 42mp sensor of the Sony A7R II is clearly out of its league. The center quality is up to the task but the quality at the outer image regions leaves something to be desired. [...] the Sony FE 28-70mm f/3.5-5.6 OSS certainly feels like a well-made lens. It may be quite affordable especially when buying it as part of a camera kit but, honestly, it is not worth it, at least if you are targeting Sony's A7R series.
