Tamron 17-70mm f/2.8 Di III-A VC RXD Lens for FUJIFILM - Brand New review
The constructors of the Tamron 17–70 mm f/2.8 Di III-A VC RXD faced a really difficult task. Every time a producer tries to offer something unique, a product no other manufacturer features, the bar is set very high, higher than usual.
very good image quality in the frame centre across the whole focal range,, sensible image quality on the edge of the frame,, lack of any serious problems with longitudinal chromatic aberration,, slight lateral chromatic aberration in the 30-70 mm focal range,, good coma correction,, moderate...
high vignetting, felt especially keenly on both ends of the focal range,, noticeable problems with spherical aberration,, performance against bright light should have been better.
