Lens posted its Tamron 17-70mm F2.8 Di III A-VC RXD review and it sounds like Tamron produced another great affordable zoom lens for E-mount. You can read the full review here or you can check out the excerpts from the review below:
“this lens managed to achieve the most important task: despite a very large and very universal focal range combined with a good, fixed f/2.8 aperture fastness, it guarantees a very good image quality across the frame, no matter what focal lenght you employ. It seems the tested Tamron performs even a tad better than you would expect, and, as such, it fully deserves a very high final assessment it got.”
Pros:
- 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 astigmatism,
- silent and very quick autofocus,
- efficient image stabilization,
- unique combination of focal range and aperture fastness.
Cons:
- 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.
