Tamron’s first E-mount lens was the 28-75mm 2.8. Compared to the 24-70mm 2.8 lenses Tamron decided to give up a bit of zoom range to realize an affordable and compact yet fast standard zoom.
This 17-28mm 2.8 shares these qualities on paper, so let us see if the optical performance can keep up with our expectations.
