Lately, Tamron released the Tamron 28-70mm f/2.8 Di III VXD G2. Despite being popular among consumers, we weren’t overly impressed by their 28-75mm f/2.8 Di III RXD (aka G1) so let’s hope that the G2 is more convincing. Tamron is listing 5 improvements over the “G1” version. Better image quality, better close focus performance, designed body, faster AF and user-customizable functions. Sounds good – on paper – so let’s have a look.
